Description

KP and K-SS Series tongue operated safety interlock switches are designed to fit to the leading edge of sliding, hinged or lift off machine guards to provide positively operated switching contacts and provide a tamper resistant, not easily defeatable key mechanism. They will provide a robust position interlock detection for moving guards.

Depending upon the risk assessment for the application, they can be used independently to provide positively operated contacts to EN60947-5-1 or they can be used in combination with any dual channel safety monitoring relays to provide up to Category 4 PLe ISO13849-1 or SIL3 EN62061. They offer a choice of various actuators to aid installation and maintain durability.

The switch is rigidly mounted to the frame of the guard or machine. The actuator is fitted to the moving part (frame) of the guard and is aligned to the switch entry aperture. The actuator profile is designed to match a cam mechanism within the switch head and provides a positively operated, not easily defeatable interlock switch. When the actuator is inserted into the switch thesafety contacts close and allow the machine start circuit to be enabled. When the actuator is withdrawn from the switch the safety contacts are positively opened and the machine circuit is broken. KP Series switches use high specification plastic housings and are sealed to NEMA 6 (IP67) and provide long term protection against moisture ingress.

K-SS Series switches have a rugged 316 stainless steel body and have been designed to cope with the rigorous applications of the food processing, pharmaceutical, packaging and petrochemical industries. They have IP69K enclosure protection and can be pressure hosed with detergent at high pressure and temperature.
