Limitless™ WLS Wireless Limit Switches
Heavy duty switch offering greater durability

Honeywell WLS Wireless Limit Switches

Honeywell Limitless™ WLS Wireless Limit Switch is a heavy duty switch from the Limitless™ Series product line, offering greater durability when used in rough applications. The Limitless™ Series combines the best of MICRO SWITCH™ Heavy Duty limit switches with the latest commercial off-the-shelf wireless technology. Honeywell's Panel-Mount Limitless™ Monitors, designed for use with wireless limit switches, can potentially monitor up to 16 wireless switches, have 10 Vdc to 30 Vdc supply with NPN Normally Open output, and a field pairing function allowing rapid configuration (add or subtract switches). Also available are wireless cable assemblies and antennas in various configurations for use with wireless switches.
