26-Position Free-Hanging Receptacle Housing for AMPMODU Mod IV
The TE Connectivity AMPMODU Mod IV 87733-4 is a 26-position, dual-row receptacle housing built for free-hanging (in-line) wire-to-board or wire-to-wire harnesses. The locking ramp fastens the housing to the mating header with an audible click — it holds the pair together under vibration without needing a secondary latch. An integrated strain relief protects the crimp terminations from cable pull, which matters when this housing sits in a harness that gets handled during assembly or service. Contacts are not included — you order the AMPMODU Mod IV crimp terminals (male or female, depending on the mating header) separately and terminate them with the standard Mod IV hand tool or automatic press.
What the Locking Ramp and Strain Relief Mean for a Harness Build
The locking ramp is the primary retention mechanism on this housing — it engages with the mating header's ramp and pulls the two halves together. In a free-hanging harness, that ramp takes the axial load from cable strain before it reaches the crimp contacts. The integrated strain relief adds a secondary grip on the cable bundle, so the wire jacket, not the terminal, absorbs the pull force. For a harness that routes through a cabinet with tight bends or periodic servicing, that pair — ramp plus strain relief — keeps the terminations intact without a separate backshell or cable clamp. The housing accepts both male and female crimp contacts, which means the same shell can serve as either the receptacle or the plug side depending on which terminal you load. That flexibility simplifies inventory if you build both halves of a harness in-house.
