Honeywell Wireless Non-Contact Switch (WLS Non-Contact Series)


Honeywell’s Limitless™ product line uses the latest commercial off-the-shelf wireless technology. The Limitless™ WLS Series is especially beneficial for remote monitoring applications where wiring or wire maintenance is not physically possible or economically feasible.

Honeywell is expanding the Limitless™ product line with its industrial Wireless Non-Contact Switch that provides non-contact presence/absence detection of a variety of different magnet styles and magnetic actuators installed on the end-users’ product, machine, equipment, etc. The Limitless™ WLS Non-Contact Switch’s design features an industrial grade reed switch. Customers can choose how the reed switch is oriented within the switch’s plastic head, i.e., either top- or side-sensing. Combining this greater flexibility with proven harsh-duty packaging can result in increased efficiencies and improved safety for industrial machines, equipment, OEMs, and operators.
