Omron D4n Series Limit Switch, IP67, 1 NO/1 NC Contact Configuration - D4N-8120

This limit switch provides a Compact electromechanical solution for detecting position changes in industrial systems. It is designed for external mounting where a roller lever actuator triggers a snap-action contact change, supplying reliable open/closed signalling for control circuits. The unit is suitable for installations requiring ingress protection and a defined operating temperature range.

Features & Benefits

• Roller lever actuator delivers precise mechanical actuation and repeatability
• Snap-action contacts switch quickly to reduce contact bounce and wear
• 1 NO and 1 NC contact arrangement supports common control logic
• IP67 rated enclosure enables use in dusty and water-exposed locations
• Plastic housing minimises weight while providing environmental protection
• 5N operating force allows compatibility with light mechanical linkages

Applications

• Suitable for automated conveyor end-of-travel detection
• Ideal for machine guarding interlock feedback in production lines
• Used with pneumatic actuators for position sensing in cylinders
• Can be used for limit detection on packaging machinery shafts

What temperature conditions can it withstand during operation?

It operates across a range from -30°C up to +70°C, allowing use in cold storage interfaces and warmer plant environments.

How long is the expected mechanical lifetime under normal cycling?

The mechanical endurance is rated at 15 million operations, supporting high-cycle industrial applications.

What conduit connection is provided for electrical entry?

The unit accepts an M20 conduit entry for standard cable gland or conduit fittings.
