Fiber optic attenuators are devices that reduce signal power in fiber optic links by inducing a fixed or variable loss. They are used to control the power level of optical signals at the outputs of light sources and electrical-to-optical (E/O) converters. They are also used to test the linearity and dynamic range of photo sensors and photo detectors

RF attenuators are circuits that reduce the power level of a signal by a certain amount (gain), with little or no reflection. They reduce the output signal with respect to the input and measure the power reduction in decibels (dB).  

Variable reluctance linear position sensors and switches are noncontact devices that use variable reluctance based technology, and whose output signal represents the distance between an object and a reference point

RF waveguide attenuators are used to reduce the power level of a signal by a certain amount (gain), with little or no reflections. The output signal is reduced with respect to the input

Variable transmissions are used in industrial applications to alter the speed of an output shaft

Linear variable differential transformer (LVDT) and rotary variable differential transformer (RVDT) signal conditioners are devices that translate the linear or rotary movement of a ferromagnetic armature into an AC voltage that is proportional to the armature position

DC motors are most commonly used in variable speed and torque applications. They include brushless and gear motors, as well as servomotors

Linear variable differential transformer (LVDT) linear position sensors have a series of inductors in a hollow cylindrical shaft and a solid cylindrical core. These devices produce an electrical output proportional to the position of the core

Resistors are electrical components that oppose the flow of either direct or alternating current. They are used to protect, operate, or control circuits.

PIN diodes are three-layer semiconductor diodes consisting of an intrinsic layer separating heavily doped P and N layers. The charge stored in the intrinsic layer in conjunction with other diode parameters determines the resistance of the diode at RF and microwave frequencies.

Resistors and potentiometers are passive electronic components that oppose the flow of either alternating current (AC) or direct current (DC). 

Adjustable speed drives alter the speed of a driven shaft to a speed selected by an operator.

Linear position sensors, all types, is a general search form for all linear position / displacement detection product areas.

Motor speed controllers are electronic devices that control motor speed. They carry specifications for drive type, product classification, electrical ratings, and operating parameters.

Stepper motors use a magnetic field to move a rotor in small angular steps or fractions of steps. They provide precise positioning and ease of use, especially in low acceleration or static load applications.
