This Moujen category focuses on Moujen heavy-duty limit switches use rugged housings for demanding machinery. MJ-family designs are available with oil/water/dust resistance, screw terminals, field-adjustable actuator heads and multiple actuator styles.
This branch sits within Moujen Industrial Switches & Limit Switches > Limit Switches > Heavy Duty. Select by enclosure/IP rating, actuator type, 45- or 90-degree travel where applicable, contact form, electrical rating, conduit thread, mounting and positive-opening needs.
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 heavy duty 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 heavy duty 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 enclosure/IP rating, actuator type, 45- or 90-degree travel where applicable, contact form, electrical rating, conduit thread, mounting and positive-opening needs.
No. Also match the switch series, contact form, electrical rating, mounting pattern, cable or conduit arrangement and environmental/safety requirements.
