The TOUCHSWITCH is a type of stainless steel sensor that has been designed to solve the problem of belt misalignment detection in zone 20 on conveyors and especially on elevators. The Touchswitch reacts to the pressure exerted on its front cover by the misaligned belt or pulley. The sensor communicates with a relay contact which triggers an alarm or stops the machine.
The sensor is easy to adjust and can be used with pressures between 2 and 5 kg. It has got a test button which allows to create an error to test the efficiency of the security system.
The Touchswitch is ATEX certified for zones 20, 21 and 22 Ex II 1D T125°C without internal cabling.
