Omron D4n Series Limit Switch, Roller Lever Actuator, IP67 - D4N-4172

This limit switch is a Compact electromechanical device designed to detect position changes and actuate control circuits in industrial systems. Housed in a plastic enclosure with ingress protection to IP67, it is intended for indoor automation and machinery applications where a robust, sealed switchhead and mechanical actuation are required.

Features & Benefits

• Snap-action contacts provide fast switching and clear signal transitions
• Rated for 10A switching current to handle standard control loads
• Operates between −30°C to 70°C for wide ambient tolerance
• Mechanical life of 15 million cycles for extended duty operation
• Plastic housing with IP67 protects internals from dust and water ingress

Applications

• Suitable for conveyor end-of-travel detection in manufacturing lines
• Ideal for actuator limit detection in packaging machines
• Used with hoist positioning and lift auxiliary sensing
• Can be used for machine safety interlocks where sealed heads are needed
• Suitable for metal-stamping press position feedback systems

What contact arrangement does it provide for control circuits?

It provides one normally open and one normally closed contact in a snap-action configuration enabling a single changeover function.

What electrical voltages can be switched with this device?

It is rated for switching at 240V AC and up to 250V DC within the specified current limits.

Are connector or conduit options available for quicker installation?

The unit accepts M20 conduit entry and compatible connectors as supplied for secure cable routing.

What operating forces and durability considerations should installers note?

The actuator requires an operating force of around 5 N and is designed for high‑cycle mechanical durability under specified operating conditions.
