Product Details

Allen-Bradley Sipha S2 Non-contact Safety Switch

The Sipha S2 is a non-contact switch in a slim ABS housing with moulded-in brackets, making it extremely versatile and simple to install. It incorporates several magnetically sensitive elements, which must be triggered in a particular sequence to operate correctly. It is designed to operate with its own actuator to help prevent the switch being defeated by a simple magnet. The Sipha S1 must be connected to the Sipha control unit to provide a monitored circuit.

Coding meets the requirements of more complex applications where simple magnetically actuated switching may not be sufficient
Head & actuator are IP67 rated, which is ideal for steam cleaning or high pressure hosing down
Non-contact actuation
Magnetic coded sensing
Slim moulded ABS housing, 82x19x19mm
Must be operated with its own safety control unit
