Product description

The SS range of electronically coded safety switches offer greater tamper resistance than standard magnetically operated switches. The units are fully encapsulated into resin filled ABS housings and have a status LED for visual indication of operation.

When the actuator is brought to the sensing part of the switch (within 8-10mm target to target) a dynamic signal is generated in the actuator and transmitted to the sensor. This signal will, along with a secondary switching system, allow the safety control relays to energise thus closing the safety contacts and opening the signal contacts.

Mounting

The SSS safety switches can approach each other from any angle.
The target on the printed face of the switch must be aligned.
Mount the switch on to the machine frame and the magnet on to the opening door.
Use the tamper proof screws provided.
Do not use the safety switch as a door stop.



Leave a minimum of 50mm between any adjacent door switch



Always try to mount the switch to non ferrous material.
Ferrous material will reduce the switching distance.

Do not mount the switch to the hinge of the door



SLIDING DOORS
EN 1088 provides some mounting suggestions, see example below.
When fixing the safety switch to a sliding door
A) ensure that when the door is opened
B) it is not easily accessible, helping prevent the system being overridden.
