The Hirose GT13S-1P/S-R is a retainer in the GT13 series — a secondary lock that slides into a GT13 housing after the terminals are loaded. The gray PBT body matches the standard GT13 housing material, so the assembly keeps a uniform thermal expansion coefficient across the mated pair. This retainer is specified wherever a field-serviceable harness needs a positive terminal position assurance (TPA) — common in automotive engine compartments, industrial sensor cabling, and any GT13-based wire-to-wire interconnect that sees mechanical shock.
Compatibility Check — Which Housing It Fits
The GT13S-1P/S-R is designed for use with GT13 housings. It is a single-position retainer — one terminal cavity per retainer. It mates with the corresponding GT13 housing that has the matching retainer slot.
