Description The Mechan SS-R Safety switches are electronic, non-contact safety switches.
Mechan’s unique electronic switching provides additional security and a single switching point leading to a more reliable and secure long term safety switching solution.
The SS-R switch is pre-wired with 5 or 10 metres of cable and has a dual colour LED and an additional volt free contact for indication, to clearly show the guard status.
The SS-R is fully encapsulated to IP67 and is suitable for use in wet , washdown or dusty areas. Its slim-line package and 10mm switching distance makes the SS-C easy to fit to most guarding systems.
With 2 x N/O and 1 x N/C contact the SS-R is ideal for use with most safety relays where category 3 or 4 performance is required for a safety application. Approvals
