Gas and air instruments detect, monitor or analyze gases present in an environment.

Light curtain controllers send stop signals to machines that are guarded by light curtains, photoelectric transmitters that project an array of synchronized, parallel infrared light beams to a receiver.

Eddy current proximity sensors and switches detect the proximity or presence of a target by sensing the magnetic fields generated by a reference coil.

Web tension indicators measure and report tension parameters in web or other flat-sheet production processes.

Proximity sensors, all types is a general search form for all proximity sensors and presence detection product areas

Photoelectric sensors use emitters and receivers to detect the presence, absence, or distance of target objects.

Ultrasonic proximity sensors use reflected or transmitted ultrasonic waves to detect the presence or absence of a target component.
