Omron D4B Series Limit Switch, IP67, 10A Switching Current - D4B-4A70N

This limit switch is a metal-housed safety device designed to detect mechanical position and provide reliable contact signalling in industrial control systems. Intended for automation and electrical installations, it operates across a wide ambient temperature range and features an ingress-protected enclosure for use in challenging environments.

Features & Benefits

• Slow-action contacts with 10A rating for moderate load switching
• Two NC contacts offering certified direct-opening safety operation
• IP67 enclosure enabling temporary immersion resistance
• Mechanical life rated at 10 million cycles for long-term service
• Rated insulation voltage 600V to suit high-voltage control circuits
• M20 conduit entry and screw terminals for secure wiring

Applications

• Suitable for machine safety interlocks requiring positive opening contacts
• Ideal for conveyor end-of-travel detection in manufacturing lines
• Used with motor control panels for position feedback in industrial systems
• Can be used for access-guard monitoring where ingress protection is needed
• Suitable for installations operating between -40°C to 80°C

What Terminal connection method does it use and what wire sizes are supported?

Termination is via screw terminals

recommended conductor sizes are 0.5 to 2.5 mm².

How does the device behave electrically under inductive loads?

Contact ratings allow switching of inductive and resistive loads with specified make/break currents

use a gI/gG 10A fuse per IEC 60269 for short-circuit protection.

Which mechanical mounting orientations are possible?

The head can be rotated and the unit mounted in multiple directions to suit installation needs.
