Product catalog summary
Overview: The KOBRA Tongue Operated Safety Interlock Switches, specifically the KP type, are designed for position interlock detection on moving guards. They are suitable for sliding, hinged, or lift-off machine guards and ensure safety by disconnecting safety contacts when the actuator is withdrawn. The switches feature an anti-tamper mechanism and a rotatable head for multiple actuator entry positions.
Specifications:
  • Rotatable head for 4 actuator entry positions.
  • Replaceable contact blocks with explosion-proof options.
  • Sealed to IP67 for durability against washdown solutions.
  • Standards: ISO14119, EN60947-5-1, EN60204-1, ISO13849-1, EN62061, UL508.
  • Mechanical Reliability: B10d 2.5 x 106 operations at 100mA load.
  • Safety Classification: Up to PLe and SIL3 depending on system architecture.
  • Body Material: Polyester; Head Material: Polyester or Stainless Steel 316.
  • Operating Temperature: -25°C to +80°C.
Functional Specifications:
  • Positive Break Contacts to EN60947-5-1.
  • High Functional Safety to ISO13849-1.
  • Available with 3 pole, 4 pole, or explosion-proof contact blocks.
  • Industry Standard Fitting: 52mm wide, 98mm long, 40mm fixing.
Contact Block Options: Various configurations available, including 2NC 1NO, 3NC, 3NC 1NO, 2NC 2NO, and 4NC. Gold plated contacts are available for low power circuits.
Accessories: Includes options for different actuator types and lengths, LED indicators, and padlock fittings for maintenance.
Application Example: The switch fits into the aperture during maintenance, providing multiple padlock holes. It can be used where poor alignment exists and allows manual insertion of the actuator by the operator.
Safety Operation: The system supports dual-channel wiring for enhanced safety, ensuring that power is isolated when the interlock switch is opened or the emergency stop is activated. Re-start is only possible when the guard is closed and the emergency stop is reset.
