Honeywell has expanded the Limitless WLS series of Heavy Duty Wireless Limit Switches with an eyelet-pull operating head that can be used to attach a rope, cable or chain. It also can be used on cranes as an anti-two-block (A2B) switch.

Honeywell's Limitless™ Series of limit switches is ideal for remote monitoring applications where wiring or wire maintenance is not physically possible or economically feasible. Combining this greater flexibility with proven harsh-duty packaging can result in increased efficiencies and improved safety for machines, equipment, OEMs, and operators.

• Enables presence/absence detection in remote parts of application/machinery, where wiring is an issue or not feasible
• Ability to reconfigure multiple switches easily allows for adding, subtracting or relocating Limitless™ WLS switches
• Reduces installation/maintenance costs with no wires, conduit, strain relief, clips, connectors, or connection boxes
• Eliminates issues with wire connection integrity on moving equipment
• Consumes ultra-low power to prolong battery life
