Product details

Auxiliary contact block for J7 contactors

The Omron J73K-B-40 is a side-mount auxiliary contact block designed for the J7 series of contactors. It adds additional N.O. or N.C. switching capacity for signal feedback or control logic without taking up extra DIN rail space.

This block clips directly onto the side of an Omron J7 contactor, sharing the same mounting footprint. The contact configuration is determined by the specific variant — the J73K-B-40 adds a set of auxiliary contacts that switch independently of the main contactor poles.

Availability and price are confirmed at quote time through independent distribution.

Frequently asked questions

Is J73K-B-40 compatible with Omron J7 series contactors?

Yes, the J73K-B-40 is designed as a side-mount auxiliary contact block specifically for the Omron J7 series contactors.

What are the differences between J73K-B-40 and J73K-B-41?

The J73K-B-40 and J73K-B-41 are both auxiliary contact blocks for the J7 series, differing in contact configuration — one provides a normally-open set, the other a normally-closed set, or a different pole count. Verify the specific contact arrangement against your control circuit requirements.
