"The Sipha S1 is a non-contact switch in a miniature 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. Miniature moulded ABS housing, 45x25x12mm.
