Motor controllers receive supply voltages and provide signals to motor drives that are interfaced to motors. They include a power supply, amplifier, user interface, and position control circuitry.

 Tachometer generators and tachogenerators are small AC or DC generators that output a voltage in proportion to the rotational speed of a shaft. They are capable of measuring speed and direction of rotation, but not position

Circuit breakers are mechanical switching devices capable of breaking currents under specified abnormal circuit conditions

Tachometers are used to measure the velocity of a rotating object. They operate on the principle that a driven motor (i.e., a motor operated as a generator) produces a voltage that is proportional to the angular velocity of the motor shaft

Printed circuit board (PCB) fabrication services design and fabricate circuit boards. They differ from electronic manufacturing services, which populate and assemble boards. 

Printed circuit boards and materials have copper-clad surfaces for the fabrication of electronic and electrical circuitry on printed circuit boards (PCBs), printed wiring boards (PWB) and  flexible circuits. Laminates and laminated materials are used to produce rigid boards. Tapes and films are used to produce flexible circuits and membrane switches

Flexible circuits use polyimide films and other foldable substrates to meet the requirements of complex electronic manufacturing applications

Device programmers are used to program nonvolatile memory such as microcontrollers, erasable programmable read-only memory (EPROM), programmable logic devices (PLDs), programmable array logic (PAL), generic array logic (GAL) and other electrically programmable devices.

Closed circuit TV (CCTV) is used for area surveillance and remote monitoring. Some systems can record events and trigger alarms

Circuit tracers or signal tracers are used to troubleshoot circuits. They are relatively simple electrical testing instruments that enable electricians and other users to locate, trace and identify common electrical problems such as breakers, shorts

Circuit protection devices are used to protect electronic components from unwanted transients such as current and voltage surges, electrostatic discharge (ESD), lightning, spikes and other signals that can imperil the operation or damage the component

Thin film circuits and products are metallized or plated onto ceramic substrates

IC timers are semiconductor circuits that generate or set timing for electronics circuits

Electrical contacts and contact materials are soft, high-conductivity, oxidation- resistant materials that are used in circuit breakers, relays, switches, and electrical discharge machining (EDM) applications.  They often have a second phase in order to provide anti-welding and/or arc resistance

Automated test equipment (ATE) is used to monitor and control test and measurement devices, keeping human interaction at a minimum.
