Omron D4B Series Plunger Limit Switch Metal Housing 2 NC Contacts 10A Switching Current 600V IP67

Omron D4B-4A70N plunger limit switch features a metal housing designed for industrial and automation applications requiring robust mechanical position detection and reliable electrical contact signaling. With its IP67 ingress protection, it is suitable for use in challenging environments where contact with dust and water is expected.

The device incorporates two normally closed (NC) slow-action contacts rated for switching currents up to 10A and voltages up to 600V AC, designed for direct-opening safety operation. It supports switching of both resistive and inductive loads when used with appropriate fuses according to IEC standards.

Constructed to operate over a wide ambient temperature range from -40°C to 80°C, the switch ensures dependable performance in diverse industrial environments. The mechanical lifespan is rated at 10 million cycles, providing extended operational reliability.

Installation is simplified with an M20 conduit entry point and screw terminal connectors supporting conductor sizes from 0.5 mm² to 2.5 mm². The multi-directional mounting capability allows flexible mounting orientations to suit various machinery configurations.

Common industrial applications include machine safety interlocks requiring positive opening contacts, conveyor position feedback in manufacturing lines, motor control panel integration, and access guard monitoring where ingress protection is critical.

Features two normally closed (NC) slow-action contacts for safety and control. Constructed with a durable metal housing for industrial durability. IP67 rated enclosure allows temporary immersion and outdoor use. Operates within a temperature range of -40°C to 80°C.

Switching capacity rated for 600V AC and 10A current. Mechanical life rated for 10 million cycles ensuring long-term reliability. M20 conduit entry and screw terminals provide secure wiring connections. Multi-directional mounting head for versatile installation.

Ideal for machine safety interlocks, conveyor end-of-travel detection, and access-guard monitoring. Explore more high-quality Limit Switches and automation components at EnvMart for your industrial system needs.
