Audio transducers and buzzers are used in electronic equipment, toys and various warning devices as the sounding component

Piezoelectric sensors measure the electrical potential caused by applying mechanical force to a piezoelectric material. They are used in a variety of pressure-sensing applications.

Piezoelectric actuators are devices that produce a small displacement with a high force capability when voltage is applied. 

Speakers produce and transmit sounds carried by electrical or radio signals.  This product category is primarily for industrial and OEM speakers rather than those for home use.

Ultrasonic transducers send and receive waves for many types of sensing. Examples include distance, proximity, level, nondestructive evaluation, web break detection, counting, and security applications

Underwater acoustic transducers contain both transmitters and receivers and use distance and directional data for communication, mapping and navigation

Piezoelectric drivers and piezoelectric amplifiers are power sources that provide the high voltage levels needed to drive other piezoelectric devices such as actuators, motors, transducers, and sensors

Electric linear actuators have an output rod that provides linear motion via a motor driven ball screw, lead screw, or ACME screw assembly. The actuator's load is attached to the end of a screw or rod and is often unsupported

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

Electric and electromagnetic wastewater and water treatment equipment uses electrical charging and magnetic energy to treat water and wastewater

Force and load sensors covers electrical sensing devices used to measure tension, compression, and shear forces.

Electro-pneumatic transducers convert current or voltage input signals to proportional output pressures. They are used as process control elements in valves, pneumatic relays, and flow regulators for applications such as spray and damper control

Electric rotary actuators drive components rotationally via electromagnetic power. They typically have control and indexing capabilities

Magnetostrictive position sensors are non-contact linear position sensors that use the momentary interaction of two magnetic fields to produce a strain pulse that moves along a waveguide. One field is from a magnet that moves along the outside of the waveguide. The other field is from the waveguide itself.
