UL 508, CSA C22-2nr.14, CEI EN 60947-5-1, EN 292, EN 418, EN 1088, EN 60204, EN 60947-5-1, IEC 204, IEC 337-1, IEC 947-5-1, NFC 63-140, VDE0113, VDE 0660, BG-GS-ET-15
Positive Break Contacts are in compliance with standards: CEI EN60947-5-1, EN 60947-5-1, IEC 947-5-1, VDE0660-206
Protection Class: IP65 (according to IEC529)
Door Operating Radius:
4 Degree to OPEN the Normally Closed Contact (maximum)
8 Degree to CLOSE the Normally Open Contact (maximum)
Switch is in the normal position when the door is closed



  1. Connect Safety Circuits to the normally closed contact (11 - 12 or 21 - 22). The normally closed contact is closed when the door is closed. These contacts open when the door rotates more than 4 degrees. The normally open contacts are open when the door is closed and are closed when the door is opened more than 8 degrees. Normally open contacts are for indicating circuits - they are not to be used in the safety circuit.
  2. Mount the switch using tamper-resistant fasteners (not supplied). Always use washers under the switch mounting fasteners to prevent the fasteners from pulling through the switch mounting holes.
  3. The head of the switch can be rotated in 4 x 90 degree steps allowing 4 different positions. To rotate the head; remove the 4 head attachment screws, rotate the head into the proper position and reinsert the head attachment screws. Head screw tightening torque = 7 inch lb. (0.8 Nm)
  4. Do not use the switch as a mechanical stop.
  5. The switch uses the rotating hinge pin of the door to activate the switch. Attach the switch at the door swing center line. Extend the door hinge pin into the hinge operated safety switch operating tube and allow the door hinge pin to rotate the operating tube.
  6. Once the switch - door hinge pin assembly is properly aligned and positioned, temporarily fix the hinge pin to the operating tube using the M4 set screw provided. Check for proper operation including the operating point for the normally closed safety contact. Once proper operation is verified, drill a hole through the hinge pin / operating tube assembly and permanently lock the hinge pin into the operating tube using the roll pin provided.
  7. Verify proper safety switch operation before placing the machine in service.
