Product Overview

Auxiliary contact blocks like the Omron J73KN-B-01A snap directly onto industrial control contactors to expand switching capabilities, enabling feedback signaling, interlocking logic, and status monitoring in motor control circuits. These supplementary poles provide secondary electrical pathways that switch synchronously with the main contactor coil.

Exact pricing, availability and lead time are confirmed per enquiry through an RFQ.
