OMRON D4N Series Limit Switch, Roller Lever

The OMRON D4N Series Limit Switch with Roller Lever is a robust and versatile safety component designed for reliable operation in demanding industrial environments. It incorporates a critical fail-safe mechanism that automatically opens the contacts in the event of a return spring fracture or contact welding, ensuring operational safety and helping to prevent machine hazards.

Its design offers exceptional flexibility for installation, as the roller lever actuating head can be mounted in four separate directions. This allows for easy integration into various machine designs and simplifies alignment with the actuating cam or target. The switch body is constructed from a heat and impact-resistant plastic resin and is sealed to IP65, providing protection against dust ingress and water jets from any direction, making it suitable for use in harsh or washdown conditions.

Conforming to major international safety standards including VDE 0660, VDE 0113, IEC-337-1, IEC-204-1, and EN 50047, this limit switch meets rigorous requirements for safety-related applications. It features a versatile contact configuration of 1 Normally Open (1NO) and 1 Normally Closed (1NC), allowing it to be used in a wide array of control circuits for functions such as position sensing, end-of-travel detection, and safety interlocking.

With a maximum operating force of just 5N, the roller lever ensures sensitive and precise actuation, while the electrical contacts are rated for a maximum of 10A at 240V AC or 2.5A at 250V DC, accommodating both common control voltages. As a key part of the proven OMRON D4N Series, this switch represents a reliable choice for engineers seeking a durable, safety-compliant, and flexible limit switch solution for automated systems and machinery.
