Omron Door Micro Switch Plunger SPDT 500 mA IP40, -30°C to 60°C

Omron D3D-111 Door Micro Switch features a plunger actuator designed for precise and reliable switching in various industrial and automation applications. This miniature door interlock switch is ideal for usage in electrical panels, machinery safety doors, and control systems requiring assured contact function.

The switch supports a SPDT (Single Pole Double Throw) contact configuration with a contact current rating of 500 mA at 250 VAC, suitable for both micro and low power loads. Its housing with IP40 rating protects the internal mechanism against solid objects greater than 1 mm, ensuring durability in typical indoor environments.

Designed for robust performance, the switch has a mechanical lifespan of 300,000 operations, backed by a low operating force of only 2 Newtons enabling sensitive and consistent actuation.

Built with gold crossbar contacts and a gold housing material, the D3D-111 provides high contact reliability and long-term stability. Installation is simplified with quick connect through-hole terminals.

This model complies with major international safety and environmental standards, including UL, CSA, VDE, and RoHS certifications, reinforcing its suitability for global industrial markets.

Operating temperature ranges from -30°C up to +60°C, allowing reliable function in a broad array of conditions commonly found in industrial, manufacturing, and HVAC applications. Compact plunger actuator for precise mechanical activation.

SPDT contact system able to switch micro and power loads reliably. Contact rating of 0.5 A at 250 V AC for low current operations. IP40 protection degree for limited ingress protection. Wide operating temperature -30°C to 60°C for versatile environments.

High durability with 300,000 mechanical cycles. Low actuation force of 2N for sensitive performance. Gold crossbar contacts provide excellent conductivity and corrosion resistance. Quick connect through-hole terminal type for ease of wiring.

Certified by UL, CSA, VDE, and compliant with RoHS standards.

Ideal for industrial automation, electrical enclosures, door interlocks, and control panels applications. Explore more components and switches within the Electronics & Electricals category on EnvMart for your assembly and equipment needs.
