Product details

What this auxiliary contact does on the line

The Omron J73KN-B-01X is an auxiliary contact block that adds signal-feedback or interlock contacts without occupying the main power poles.

Compatibility and fit with J7KCN contactors

This block clips directly onto the front or side of compatible Omron contactors, sharing the same mounting footprint and electrical interface. The contact configuration is a standard auxiliary block; the "B" in the order code typically denotes a specific contact arrangement (e.g., 1 N.O. + 1 N.C.), though the exact pole count should be confirmed against the panel schematic.

No official successor or cross-reference part number is recorded — the J73KN-B-01X is the active order code for this auxiliary contact function.
