The GLS-SS is general duty safety rope pull switch designed to protect long conveyor lengths up to 100m.
The Stainless Steel 316 housings are designed specifically to withstand the harsh environments found in the food and pharmaceutical industries. The fixing holes are under the cover of the switch to prevent food trap areas and will survive chemical and detergent washdown by providing all stainless steel parts and robust IP67 and IP69K sealing by ysing integral bellows and gaskets.
An easily visible bi-colour LED is available to show switch status from a distance and they have a choice of 3 pole, 4 pole or explosion proof contact blocks to ensure flexibility with all modern control applications.
Shorter rope spans up to 80m can be achieved by using just one switch therefore making a cost-effective solution and also reducing electrical wiring runs.
