Be sure to tighten each screw screws for the head and switch box with the following torques: to the proper tightening torque as shown in the table. Head (four 12-mm M4 screws): 1.2 to 1.4 N·m Switch box (two 20-mm M5 screws): 2.4 to 2.7 N·m Solderless Terminals The D4A-@N with DPDT double-break incorporates solderless terminals. Operation • The operating methods, cam and dog shapes, operating frequency, and overtravel (OT) have a significant effect on the service life and accuracy of the Limit Switch. The shape of the cam should be as smooth as possible. • A marginal overtravel (OT) value should be set. The ideal value is the rated OT value x 0.7. • The actuator should not be remodeled to change the operating position. Connectors To satisfy IP67, apply sealing tape to the connector conduit. Appropriate external diameter of cables is 5.5 to 14 dia. Use OMRON’s SC-@M Series. Tighten the Connectors to a torque of 1.8 to 2.2 N·m. Maintenance and Repair Appropriate tightening The user must not maintain or repair equipment incorporating any No. Type torque D4A-N model.
