Safety position switches LS4…ZB, LS…ZB [t-head1-pg]
Moeller safety position switches have been specially designed for monitoring the position of protective guards such as doors, flaps, hoods and grilles. They meet the requirements of the German Trade Association for the testing of positively opening position switches for safety functions (GS-ET-15). These reqquirements include:
“Position switches for safety functions must be designed so that the safety function cannot be bypassed manually or with simple tools.” Simple tools are: pliers, screwdrivers, pins, nails, wire, scissors, penknives etc.
In addition to these requirements, LS...ZB position switches offer additional manipulation safety by means of an operating head which can rotate but cannot be removed.
