This Moujen category focuses on positive-opening limit switches that mechanically force the normally closed safety contact open for applications requiring direct-opening action; Moujen identifies IEC/EN 60947-5-1 positive-opening designs in this family.
This branch sits within Moujen Industrial Switches & Limit Switches > Limit Switches > Positive Opening. Select by positive-opening contact requirement, actuator type, safety-circuit design, electrical rating, environmental sealing, conduit/cable entry and mechanical travel.
In machine-control service, actuator geometry and travel are as important as the contact rating. The target should operate the switch positively without using the switch body or actuator as a mechanical stop.
Use the full Moujen series and actuator code when replacing an existing positive opening device. Housings that look similar may differ in contact action, cable entry, sealing or operating characteristics.
For a new application, document the normal target position, direction of motion, expected travel, switching load and exposure to dust, water, oil or washdown before choosing the switch.
Where positive opening is used in a guard or safety-related circuit, the complete machine-safety architecture and applicable standards must be considered; selecting a switch with a safety feature does not by itself make the machine safety function complete.
Verify positive-opening contact requirement, actuator type, safety-circuit design, electrical rating, environmental sealing, conduit/cable entry and mechanical travel.
No. Also match the switch series, contact form, electrical rating, mounting pattern, cable or conduit arrangement and environmental/safety requirements.
