Omron D4n Series Limit Switch, 64mm Length, IP67 - D4N-4A2G


This limit switch is a Compact industrial device designed to monitor mechanical movement and provide electrical switching in automation and control systems. It is housed in a robust metal and resin assembly with an adjustable roller lever actuator and an M20 conduit entry, offering sealed operation in applications where dust or temporary immersion may occur. It suits engineers specifying a 1 NO/1 NC slow-action switching element for standard load control.

Features & Benefits


• IP67 protection enabling temporary submersion resistance
• Switching capacity up to 10A at 240V AC for mains loads
• Slow-action contacts supporting 250V DC switching where required
• Mechanical life rated at 15 million cycles for long-term duty
• Operates across −30°C to 70°C for wide ambient range
• Direct-opening NC mechanism for safety-oriented contact separation

**Applications**


• Suitable for conveyor end-of-travel detection in factories
• Ideal for machine-tool limit detection in production cells
• Used with elevator and lift systems requiring EN conformity
• Can be used for panel interlocks in wet-environment enclosures
• Suitable for automated packaging line position sensing

What kind of actuator options are available for field adjustment?


The head accepts an adjustable roller lever with form-lock engagement and both resin and metal lever variants to set actuation angle and length.

How should wiring be protected to maintain the ingress rating?


Use recommended connectors or conduit adaptors and tighten to the specified torque

fit seal packing for M20 connections to preserve IP67.

What is the electrical endurance under resistive loads?


Electrical durability is specified for hundreds of thousands of operations depending on load, with tested values for resistive loads at rated currents.
