Where It Fits — M Series Connector Family
This guide pin is designed for use with TE's M Series rectangular connectors — a family of heavy-duty, industrial-grade interconnects used in control cabinets, machinery, and power distribution. The guide pin installs into the connector housing and protrudes to engage the mating half before the contacts touch, preventing bent pins and misalignment. Packaged in Bulk. No mating cycle rating is listed for the guide pin itself — its service life is limited by the connector assembly it is installed in.
