Leading Manufacturer of Safety Interlock Switches and Machine Guard Safety Switch Devices for Automation and Process Safety

Non-Contact Safety Switch Gate Bolts

The GBN Gate Bolt range for non-contact switches are equipped with a mechanical bolt and a handle, eliminating the need for costly in-house engineering.

The GBN-3 gate bolt features instant unlocking from inside the guarded area, which is held by springs only. When re-start is required, deliberate re-closing is necessary and the instant rear escape release mechanism allows operators to quickly exit the hazardous area. This feature eliminates the need for tools or keys to allow for instant rear escape in case of emergency.

With over 30mm (1 1/4″) adjustability, the handle bracket and switch bracket mounting holes are slotted to compensate for varying door gaps. The stainless steel guide provides up to 10,000N holding force, ensuring the safety switch remains correctly aligned and preventing accidental closure.

Overall, the GBN Gate Bolt range offers reliable and precise interlocking for safety applications in various industries.

Suitable for Non-Contact Switch Types:

SPR, SMR, SMR-H, LPR, LMR, SPC, SMC, SMC-H, LPC, LMC, LPF, SPF, LPZ, LMZ
