Pilz PSENme 4.2 User Manual
Installation and Operating Instructions
Plastic encased safety interlocking switch
Type
Intended use
The plastic encased safety switches PSEN me4 with separate actuator are suitable for the mounting on safety
guards. They are designated to trigger switching operations in control circuits.
Function
If the safety guard is opened the contact(s) with forced disconnection will break the safety control circuit (safety
contacts get opened).
Improper installation or manipulation of the safety switch renders the personal protection function useless and can
cause serious injury or accidental death.
In order to maintain the maximum level of safety, always order and use actuators together with the correct safety
switches.

Installation
Installation by trained and qualified personnel only!
To mount the switch gear 2 screws M5 shall be used.
Actuator PSEN me4AS:
The user shall make sure that the actuator is form-fit mounted. The actuator mounting should not be solvable with
simple tools. For a tamperproof mounting use one-way screws of M 4X8 size.
The switch and the actuator shall be aligned during installation in such a way that even after multiple actuations of
the safety guard no lateral forces affect the actuator head.
The mounting position is any desired but shall support inspection and replacement if necessary by qualified
personnel. Choose such a mounting position that no foreign parts seep into the opening of the actuating device.
The rated degree of protection (IP-Code) of the switch applies only with closed cover lid and when an at least
evenly matched cable gland with adequate cable is used.
The switches shall not be used as mechanical end stop.
