Omron D40ML Safety Interlock Switch, Actuator Actuator Included, Plastic, Magnet

This safety interlock switch is a sealed magnetic actuator interlock designed to monitor and secure guards and access points in industrial machines. It combines RFID-based coding with magnetic latching to provide tamper resistance and retention of guards when power is applied, operating across a controlled ambient range and suitable for use where sealed protection and electrical switching are required.

• 4 safety contacts provide dual-channel safety outputs up to 200 mA
• Magnetic actuator interlock D40ML offers high holding force
• IP67-rated enclosure resists ingress during washdown and routine cleaning
• Operates from 24 V DC supply for straightforward control integration
• LED diagnostics indicate guard open, closed or unlocked status
• Designed for operation between -25°C and 40°C ambient temperatures

• Suitable for machine guards with no rundown time requirements
• Used with dual-channel safety relays for PLe/Cat.4
• Ideal for hygienic environments when stainless steel selected
• Can be used for series connection of up to 20 switches
• Employed where tamper-resistant access control is required

The contacts are rated for switching up to 250 V AC and 24 V DC with a maximum switched current of 200 mA.

Internal LEDs show closed (green), open (amber) and solenoid unlock states for Rapid fault diagnosis.

Actuators are available as identically coded (basic) or individually coded (unique) with millions of codes to prevent unauthorised substitution.

Holding force varies by housing and duty level, with medium and heavy duty options delivering hundreds to over a thousand newtons.

Use two M5 fasteners tightened to 1.0 Nm torque, mount on non-ferrous material, and maintain face-to-face alignment for nominal holding force.
