Omron D4n Series Limit Switch, IP67, 10A Switching Current - D4N-4A20R

This limit switch provides a Compact mechanical position-sensing solution for industrial control and safety interlocks. Designed for harsh indoor environments, it employs a roller lever actuator and snap-action contacts to detect motion or end-of-travel events while offering a sealed enclosure for dust and water resistance.

Features & Benefits

• IP67 rated sealed housing for wet-condition protection
• Snap-action contacts support 10A switching at 240V AC
• Roller lever actuator requires 6.4N operating force
• Screw terminals accept wiring up to 250V DC applications
• Multi-directional head allows flexible mounting orientations
• Mechanical life rated to 10,000,000 cycles for high duty

Applications

• Suitable for conveyor end-of-travel detection in plants
• Ideal for machine guard interlocks requiring manual reset
• used with motor control panels for position feedback
• Can be used for packaging equipment limit sensing
• Suitable for assembly-line safety monitoring and stops

What electrical load types can it handle reliably?

It is designed for standard resistive loads up to 10A at 240V AC and limited DC switching up to 250V with specified current ratings.

How does the device behave in corrosive or oily atmospheres?

The body is plastic with IP67 sealing but the head is not impervious to fine contaminants, so avoid locations where oil, metal dust, or chemicals can ingress the actuator area.

What mounting and wiring considerations are required?

It fits M4 mounting and accepts M20 conduit entries

Terminal screws should be tightened to specified torques and crimp Terminals must be no thicker than 0.5mm.

How are contact arrangements provided for safety circuits?

The unit includes a 1NO/1NC slow-action snap contact set with direct-opening NC contact geometry to support approved disconnection behaviour in safety-related circuits.

Can it be used in high-frequency cycling applications?

Rated for specified operating frequency up to 30 operations/min and defined electrical durability figures, assessment under actual conditions is advised before continuous high-rate use.
