Omron Limit Switch, Industrial Control Component - D4N-1126

This limit switch is a Compact industrial device designed to detect mechanical position changes and provide electrical switching for automation and safety circuits in machinery. It is intended for indoor use where dust and water exposure is controlled and offers a choice of actuator styles and conduit/connector options to suit installation needs in production, material handling and control panels.

Features & Benefits

• IP67 protection rating for use in wet or dusty environments
• Rated for 10A thermal current and 100A conditional short‑circuit current
• Mechanical durability 15,000,000 operations for long service life
• Electrical endurance up to 500,000 operations at 3A, 250VAC for frequent switching
• Direct‑opening NC contacts to separate contacts under deposit conditions
• Snap‑action option providing fast contact operation for precise control

Applications

• Suitable for position detection on conveyor indexing mechanisms
• Ideal for safety interlock circuits on access guards and doors
• Used with hoists and lifts for end‑of‑travel sensing in control panels
• Can be used for limit sensing on stamping and forming presses
• Suitable for machine‑tool tool‑change and automated handling stations

What contact arrangements are available and how do they affect wiring?

Multiple contact forms are provided including single changeover, double NC and three‑NC configurations

selection determines Terminal assignments and whether direct‑opening NC paths are present for safety‑orientated wiring.

How should I choose the conduit or connector for panel integration?

Options include Pg13.5, G1/2, 1/2‑14 NPT, M20 and M12 connector types

choose the thread or connector type compatible with your enclosure and regional conduit standards and use recommended tightening torques.

What thermal and insulation limits should be observed during installation?

The device has a rated insulation voltage of 300V and a rated operating current in utilisation categories such as AC‑15 at 3A

ensure load currents and fuse protection follow specified ratings to avoid overload.

How does the device behave under high‑frequency operation?

Electrical durability depends on switching frequency and load

verify correct operation with the intended load and duty cycle since endurance values vary with operating conditions.

Are there lever and actuator variations for different mechanical interfaces?

A wide range of actuators is available including roller levers, plungers, roller plungers and fork levers to match different actuation geometries and force requirements.
