Nector M Contact Lock Positioner, 3 Positions
The TE Connectivity 1-2213396-1 is a contact lock positioner from the Nector M series, a 3-position accessory that retains crimped contacts in the housing before the connector is mated. It acts as a secondary lock — the positioner slides into the housing after the contacts are inserted, pushing the contact lances into their locked position and providing a visual confirmation that each terminal is fully seated. This is a standard practice on Nector M harness assemblies where vibration or service access makes terminal retention critical. The housing is molded from black Polybutylene Terephthalate (PBT) with glass fill, a material choice that gives the positioner dimensional stability under the clamp load of the terminal lances and resists creep at the connector's rated operating temperature. The black color matches the standard Nector M housing color for visual consistency on the assembly line.
Compatible Contacts and Installation
This positioner is designed for use with Nector M crimp contacts. The 3-position layout aligns with a 3-circuit Nector M housing — the positioner indexes into the housing cavity and locks over the contact retention lances.
