Omron D4B Series Roller Lever Limit Switch, 1 NC/1 NO, IP67, Metal Housing

This limit switch is a rugged industrial switch designed to detect mechanical position changes and provide reliable electrical signalling in automation environments. It features a roller-lever actuator housed in a metal enclosure and is intended for use where robust ingress protection and a wide operating temperature range are required. The product is suitable for control panels and machinery interfaces where discrete contact feedback is needed.

• Roller-lever actuator delivers precise mechanical detection and actuation
• Metal housing provides Durable protection in harsh conditions
• IP67 rating enables operation in wet and dust-prone environments
• Operates between -40°C to 80°C for wide temperature tolerance
• Slow-action contact improves stable switching for controlled circuits
• Mechanical life of 30 million operations reduces maintenance frequency

• Suitable for conveyor end-of-travel sensing in heavy industry
• Ideal for machine-tool limit detection where moisture is present
• Used with automated packaging lines requiring long-life switches
• Can be used for gate and access control position feedback
• Used for safety interlocks in electrical control cabinets

It employs M3.5 round crimp terminals for secure conductor attachment in control wiring.

Cable ingress is accommodated via an M20 conduit entry to Interface with standard industrial conduits.

It provides one normally closed and one normally open contact, allowing both break and make signalling in control circuits.
