DC motors are most commonly used in variable speed and torque applications.

Industrial liquid handling pumps are classified in many different ways, and are distinguished by the media pumped and the fluid motive mechanism (dynamic or displacement).

Solid state relays (SSR) or semiconductor relays are semiconductor devices that can be used in place of mechanical relays to switch electricity to a load in many applications.

Lamps are light sources that emit incoherent light for illumination.

Light-emitting diodes (LED) are PN junction devices that give off light radiation when biased in the forward direction.

Temperature instruments use contact or noncontact methods to measure temperature.

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