APPLICATION:
Coded Non Contact switches are designed to interlock hinged, sliding or removable guard doors. They are specifically advantageous when:
a) poor guard alignment exists
b) anti-tamper is required
c) high hygiene requirements exist e.g. food industry hose down
d) a long mechanical life is required (no moving or touching parts).
When used in combination with a Dual Channel Safety Relay or Control Device, Coded Non-Contact Switches can be used to provide protection up to Category 4 and PLe to ISO13849-1.
