About the Omron D4N-8120
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.

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.
