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

Safety relays and control modules differ from conventional relays in that they have force-guided or positive-driven contacts

High voltage relays are used to transfer power for high voltage and high frequency applications. They are heavily insulated and consist of strong materials to increase contact life

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

Specialty relays and accessories are specialty or proprietary products and accessories related to relays

Electrical current sensors measure AC and/or DC current levels. They receive current inputs and provide outputs as analog voltage signals, analog current levels, switches, or audible signals.

Electrical charge sensors measure electrical charge.

Flow controllers monitor and maintain proper humidity levels in environmental test applications, or in other areas such as food storage or electronic room regulation.

Frequency sensors measure the frequency of an electric signal.

Electrical resistance and conductance sensors measure the resistance or conductance of an electrical component or system.

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

Specialty materials includes specialty or proprietary materials that are not part of other areas.

Antennas are structures or devices used to collect or radiate electromagnetic waves

Gas flow switches and liquid flow switches, velocity, are used to measure the flow or quantity of a moving fluid in terms of velocity, such as feet per minute.

Mass liquid flow switches and mass gas flow switches are devices used for measuring the flow or quantity of a moving liquid or gas in terms of a unit of mass per unit time, such as pounds per minute. These devices may be sensors with electrical output or may be stand-alone instruments with local displays and controls.
