DC Universal-Object Proximity Switches
Also known as capacitive proximity switches, these remotely sense both metallic and nonmetallic objects, but their strength is in sensing materials such as plastic, ceramic, and clear targets. Sensing distance is based on the type of material being sensed. The distance listed is for mild steel. Often used with programmable logic controllers (PLCs), they produce PNP or NPN signal output. To determine the signal output of a switch you are replacing, use Testers for Proximity and Photoelectric Switches (not included).
Projecting switches, also known as non-embeddable or unshielded switches, must be mounted with the area around the sensor face free of metal. They have a longer sensing distance than flush switches with the same diameter.
Switches rated IP67 are protected from temporary submersion. Also available: If you don’t see the switch you need, please select 6693T999 and specify manufacturer and manufacturer part number.
