About the Omron D4N-9B31

The actuator geometry, contact action and cable-entry arrangement distinguish variants in this family. A matching housing appearance alone does not establish that two switches can replace each other.

What is the D4N-9B31 used for?

Mechanical position or travel detection in machinery. Any use in a safety function requires the exact manufacturer ratings and application validation.

Lifecycle and successor

To be confirmed.

Before you order

What to photograph or confirm so the right unit is quoted.

Match the complete part number and actuator type. Confirm operating direction, travel, force, mounting dimensions and mechanical clearance. Check normally-open/normally-closed contact counts and switch action against the circuit. Confirm conduit size, connector or cable length and the required environmental rating. For safety-related applications, verify the exact model documentation and the complete circuit design before selection.
