Frequently Asked Questions
Why are female crimp contacts installed into unused Samtec connector positions?
Unused positions in Samtec housings (such as spare pins on J6, J10, J601, and J101) are fitted with 20 AWG female crimp contacts to ensure uniform mechanical retention, prevent terminal cavity deformation, and maintain connector mating stability.
What transducer interface is integrated into this cable harness?
The harness integrates two Delphi 12110192 3-pin sealed connectors with 12089290-L terminals, specifically engineered for direct mating with industrial fluid, oil, or pneumatic pressure transducers in high-vibration environments.
What electrical quality verification standard does this assembly follow?
Every assembly is manufactured and 100% tested in accordance with IPC/WHMA-A-620 Class 2 standards, verifying point-to-point pinout mapping, contact continuity, and absence of electrical shorts before dispatch.
Overview and Application Notes
This multi-branch industrial wire harness assembly integrates a 26-pin MIL-DTL-26482 bayonet circular receptacle with high-density Samtec Mini-Mate rectangular connectors (4-pin, 8-pin, and dual 24-pin) and two sealed Delphi Metri-Pack pressure transducer interfaces. Fabricated with 20 AWG discrete conductors, multiple breakout lengths, and heat-shrink identification sleeves, it is engineered for critical digital output, analog sensor acquisition, and speed telemetry in industrial machinery and rail transit control systems.
Key Features
- Multi-Branch Architecture: Breaks out a 26-pin bayonet circular receptacle into 4 discrete Samtec housings (J10, J601, J6, J101) and 2 sealed Delphi 3-pin transducer connectors.
- Staggered Branch Geometry: Centerline-measured branch lengths spanning 9.5″, 12.0″, 14.0″, 15.0″, and 27.0″ to conform to compact enclosure routing.
- Integrated Pressure Sensing: Dedicated Delphi Metri-Pack 3-pin interfaces with sealed terminals for direct connection to fluid/air pressure transducers.
- Full Traceability & Marking: Labeled with 42 heat-shrink wire markers and a self-laminating cable jacket wrap for field service diagnostics and maintenance.
- IPC/WHMA-A-620 Class 2 Workmanship: Manufactured and 100% verified for point-to-point pinout mapping, continuity, and short circuits.
Engineering Specifications & System Integration
Designed for mission-critical industrial I/O and telemetry racks, the assembly utilizes size 20 crimp socket contacts within an MS3122E16-26S circular shell. Branch lines terminate into positive-latch Samtec IPD1-series female housings and environmentally sealed Delphi Metri-Pack connectors. In compliance with assembly notes, all unused Samtec cavity sockets are pre-loaded with size 20 female crimp contacts to ensure cavity integrity and balanced mechanical retention. Length tolerances follow standard IPC/WHMA-A-620 Class 2 specifications (+2.0″ / -0.0″ for spans under 60″), ensuring drop-in cabinet integration.
