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. PROTECTION UP TO 250 METRES.
Shorter rope spans up to 200m can be achieved by using just one switch therefore making a cost effective solution and also reducing electrical wiring runs. A Low Temperature -40C version (GLHD-FZ) is also available.
