GLHD

IDEM GLHD Guardian Line Heavy Duty Rope Switch.

IDEM's GLHD Heavy Duty Safety Rope Pull Switch is designed to protect long conveyor lengths. The die-cast housings are extremely robust and survive indoor or outdoor use including washdown (IP67 rating).

Lengths over 2Km can be achieved with less than 20 switches.

A bi-colour LED ensures switch status can be seen easily from a distance. They have 4NC 2NO contacts to ensure flexibility with all modern control applications and optional Explosion Proof contact blocks are available.
