Description
The DEUTSCH M34-18-21PN is a 21-way HD30 receptacle connector-half kit built around the genuine HD34-18-21PN housing. It supplies pin contacts for crimp termination and normal seals for a serviceable circular connection on compatible vehicle, agricultural, off-highway and industrial wiring.
This is one connector half, not a full mating pair. The matching plug must be ordered separately. Plug/receptacle describes the housing style; pin/socket describes the contact type.

Contact Selection
- Size 20: 0460-202-20141, 20 AWG; rated up to 7.5 A per contact under the manufacturer’s specified conditions
Current ratings apply to individual contacts, not the combined connector. Conductor size, temperature, circuit loading and installation affect allowable current. The wire conductor must fit the contact and its insulation must fit the housing seal; these are separate checks.
Compatibility & Installation
Match the opposite housing style, shell size, cavity arrangement and complementary pin/socket contacts. Check keying, any modification suffix and the wire-seal requirements against the manufacturer documentation. N, T and E seal variants are not interchangeable wire-size specifications.
Crimp using tooling suitable for the supplied contacts, insert from the rear and check retention. Close unused cavities with the correct sealing blanks. Follow the HD30 assembly instructions before mating and locking the bayonet coupling. Wire, crimping tools, backshells, dust caps and the mating connector half are not included. The listed nut and lockwasher are included.
