Proximity Sensor able to detect the presence of nearby objects without any physical contact.
A proximity sensor often emits an electromagnetic field or a beam of electromagnetic radiation (infrared, for instance), and looks for changes in the field or return signal. The object being sensed is often referred to as the proximity sensor's target. Different proximity sensor targets demand different sensors. For example, a capacitive photoelectric sensor might be suitable for a plastic target; an inductive proximity sensor always requires a metal target.
The maximum distance that this sensor can detect is defined "nominal range". Some sensors have adjustments of the nominal range or means to report a graduated detection distance.
Proximity sensors have high reliability and long functional life.
Proximity sensors used in machine vibration monitoring to measure the variation in distance between a shaft and its support bearing. This is common in large steam turbines, compressors, and motors that use sleeve-type bearings.

1. Cooling Fan:
Cooling fans and blowers essential to systems that produce a significant amount of heat like computers and other electronic components. Cooling fans come in all shapes and sizes as well as voltage, airflow, and case size. Some weather resistant and can stand up against the elements.
Different Fans for Different Systems
Axial fans: designed to work with systems that have low back pressure and require less noise.
Blowers: designed to work with systems that have high impedance (i.e. back pressure). Blowers produce a more concentrated airflow in a system. As a result, they tend to generate a significant amount of noise.

1. Load Cell
Load Cell transducer converts input mechanical force into electrical output signal. Load Cells commonly known as Load Transducers or Load Sensors.
Types of load cell & Application-
Compression load cells recognized as the benchmark for high capacity column load cells.
• Truck and railroad scales
• Tank and silo weighing
• Ultra-high capacity industrial scales
Single Ended Load Cell:
Single point load cells used for general measurement and weighing, Retail scales, Dynamic weighing machinery, Industrial bench and floor scales, On-board vehicle weighing equipment.
Shear Beam Load Cell:
Shear beam load cells ideally suit all industrial weighing scale and general measurement applications
S-Type Load Cell:
S-type load cells is ideally suited for process weighing and general measurement applications such as tensile testing machines
Hydraulic Load Cell:
The piston is placed in a thin elastic diaphragm. The piston doesn't actually come in contact with the load cell. Mechanical stops are placed to prevent over strain of the diaphragm when the loads exceed certain limit. The load cell is completely filled with oil. When the load is applied on the piston, the movement of the piston and the diaphragm arrangement result in an increase of oil pressure which in turn produces a change in the pressure on a bourdon tube connected with the load cells
Pneumatic load cells:
The load cell is designed to automatically regulate the balancing pressure. Air pressure is applied to one end of the diaphragm and it escapes through the nozzle placed at the bottom of the load cell. A pressure gauge is attached with the load cell to measure the pressure inside the cell. The deflection of the diaphragm affects the airflow through the nozzle as well as the pressure inside the chamber.
Strain gauge load cells:
These are the most common, there are other types of load cells as well. In industrial applications, hydraulic (or hydrostatic) is probably the second most common, and these are utilized to eliminate some problems with strain gauge load cell devices. As an example, a hydraulic load cell is immune to transient voltages (lightning) so might be a more effective device in outdoor environments.

Bearing is a device that is used to enable rotational or linear movement, while reducing friction and handling stress.
Types of Bearings
Ball Thrust Bearings:
These kinds of bearings are designed to handle almost exclusively thrust loads in low-speed low-weight applications. Bar stools, for example, make use of ball thrust bearings to support the seat.
Roller Thrust Bearings:
Roller thrust bearings, handle thrust loads. The difference lies in the amount of weight the bearing can handle: roller thrust bearings can support significantly larger amounts of thrust load, and are therefore found in car transmissions, where they are used to support helical gears. Gear support in general is a common application for roller thrust bearings.
Tapered Roller Bearings:
This style of bearing designed to handle large radial and thrust loads—as a result of their load versatility, they found in car hubs due to the extreme amount of both radial and thrust loads that car wheels expected to carry.
Ball bearings used in most applications that involve moving parts. Some of these applications have specific features and requirements:
• Hard drive bearings used to be highly spherical, and were said to be the best spherical manufactured shapes, but this is no longer true, and more and more are being replaced with fluid bearings.
• Aerospace bearings used in many applications on commercial, private and military aircraft including pulleys, gearboxes and jet engine shafts. Materials include M50 tool steel (AMS6491), Carbon chrome steel (AMS6444), the corrosion resistant AMS5930, 440C stainless steel, silicon nitride (ceramic) and titanium carbide-coated 440C.
. Motor –
An electric motor is an electric machine that converts electrical energy into mechanical energy.
Stepper motors consist of a doubly salient structure (teeth on both the rotor and stator) and are used primarily in applications requiring precise position control which cannot justify the cost of expensive position feedback sensors
Brushed DC Motor
DC motors typically consist of a rotating armature coil inside of a stationary magnetic field which is generated by either a permanent magnet or a stationary electromagnet connected in series or parallel with the armature coil (the series connection often being referred to as a Universal Motor).
Brushless DC Motor (BLDC) Although the name implies a DC motor, it is actually an AC motor. Concentrated coil windings on the stator work in conjunction with surface mounted magnets on the rotor to generate a nearly uniform flux density in the airgap. This permits the stator coils to be driven by a constant DC voltage (hence the name brushless DC), which is simply switched from one stator coil to the next. This process (referred to as COMMUTATION) must be electronically synchronized to the rotor angular position, and results in an AC voltage waveform which resembles a trapezoidal shape. Since there are no brushes or commutator, the BLDC motor does not exhibit the arcing problems associated with a brushed DC motor.
AC Induction Motor (ACIM)
AC Induction Motors were the electric workhorse of the industrial revolution. The rotor consists either of multiphase windings, or the more popular copper or aluminum bars arranged in a structure that resembles a squirrel cage. Essentially a rotating transformer, currents are "induced" in the rotor conductors (secondary) from the stator coils (primary). The absence of permanent magnets makes AC induction motors extremely rugged and robust. Sinusoidal flux density is created in the airgap which is generated by sinusoidally distributed multi-phase stator windings. Field Oriented Control (FOC) is often employed to control these motors, which requires precise knowledge of the rotor angular position. However, due to the damping action provided by the moving rotor conductors, AC induction motors are also capable of simply running open loop from a multi-phase AC supply.

A battery is a device that converts stored chemical energy to electrical energy. Batteries are commonly used as energy sources in many household and industrial applications.
There are two types of batteries: primary batteries (disposable batteries), which are designed to be used once and discarded, and secondary batteries (rechargeable batteries), which are designed to be recharged and used multiple times. Batteries come in many sizes, from miniature cells used in hearing aids and wristwatches to room-size battery banks that serve as backup power supplies in telephone exchanges and computer data centers.

An encoder is a device, circuit, transducer, software program, algorithm or person that converts information from one format or code to another, for the purposes of standardization, speed, secrecy, security, or compressions.
A rotary encoder, also called a shaft encoder, is an electro-mechanical device that converts the angular position or motion of a shaft or axle to an analog or digital code.
A linear encoder similarly converts linear position to an electronic signal.

• Hybrid Coupler
• Power Tapper
1.POWER SPILLTER=. Power dividers (also power splitters and, when used in reverse, power combiners) and directional couplers are passive devices used in the field of radio technology. They couple a defined amount of the electromagnetic power in a transmission line to a port enabling the signal to be used in another circuit. An essential feature of directional couplers is that they only couple power flowing in one direction. Power entering the output port is coupled to the isolated port but not to the coupled port.
2. Hybrid Coupler=A hybrid coupler is a passive device used in radio and telecommunications. It is a type of directional coupler where the input power is equally divided between two output ports. Since it is a special case of directional coupler, it is discussed in Power dividers and directional couplers.
3. Attenuator=An attenuator is an electronic device that reduces the power of a signal without appreciably distorting its waveform.
An attenuator is effectively the opposite of an amplifier, though the two work by different methods. While an amplifier provides gain, an attenuator provides loss, or gain less than 1.
Attenuators are usually passive devices made from simple voltage divider networks. Switching between different resistances forms adjustable stepped attenuators and continuously adjustable ones using potentiometers. For higher frequencies precisely matched low VSWR resistance networks are used.
4. Terminator (electrical), a resistor at the end of a transmission line to prevent signal reflection
5. RF CONNECTOR=A coaxial RF connector is an electrical connector designed to work at radio frequencies in the multi-megahertz range. RF connectors are typically used with coaxial cables and are designed to maintain the shielding that the coaxial design offers.
