Electronic counters and electronic timers are completely electronic units for performing a variety of counter or timer functions

Electromechanical counters and electromechanical timers accept inputs to operate mechanical display, such as rotating wheels or knobs

Time delay relays and solid state timers use solid state electronic devices to provide a time delay

Specialty timers are specialty or proprietary products related to timers and timing devices

Electromechanical relays are devices that complete or interrupt a circuit by physically moving electrical contacts into contact with each other

Tool turrets are indexing tool holders for lathes, transfer machines, and other machine tools. They allow equipment to carry multiple cutting tools at one time and mount individual tools in the correct sequence.

Relay sockets are devices that accept relays, electromechanical switches in which the variation of current in one electric circuit controls the flow of electricity in another circuit

Test equipment and instrument repair services test and repair industrial equipment and instruments. They specialize in the test and repair of acoustic and vibration equipment, electrical and electronic test equipment, laboratory equipment and instruments, inspection instruments or non-destructive testing (NDT) equipment, or specialty testing equipment and instruments.

Industrial keyboards are peripheral hardware devices that include alphanumeric keys, electromechanical buttons, or sensors that users press to interface with a computer.  

Counter and timer boards are computer cards that perform digital counting and/or timing functions

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

Mechanical timers are used to actuate devices at the end of a specified time period. They do not require electrical power and can be stored for long periods of time

Specialty IC timing devices are specialty or proprietary products related to IC timing devices.

Electrical and electromechanical assembly services provide board-level assembly, chassis and rack panel wiring, and front panel assembly. Typically, suppliers provide the complete turnkey production of electronic and electromechanical finished products from procurement through final assembly with testing and burn-in, if required

IC phase-locked loops (PLL) are closed-loop frequency controls that are based on the phase difference between the input signal and the output signal of a controlled oscillator.
