What are the key features of TST-136-04-H-D?
- 72-position dual-row 0.100" pitch shrouded PCB header with polarizing shroud preventing mis-mating in high-channel-count board-to-cable assemblies
- High-profile (H) contact design accommodating mating connector insertion from standard ribbon cable connectors with secure retention in industrial and embedded applications
- Dual-row layout delivering 36 contacts per row for dense signal busing within a 0.100" pitch footprint widely supported by ribbon cable and IDC connector systems
What is TST-136-04-H-D used for?
The TST-136-04-H-D is suited for board-to-cable and board-to-board signal distribution in industrial control systems, embedded computing platforms, and test equipment requiring reliable 72-pin dual-row shrouded header connections at 0.100 inch pitch. The polarizing shroud prevents reverse connector insertion during field assembly, reducing wiring errors in complex multi-connector panels. Its high-profile contact design is compatible with standard 0.100 inch pitch IDC ribbon cable connectors widely used in data acquisition and control system wiring.

Frequently Asked Questions
How does the polarizing shroud on TST-136-04-H-D protect against wiring mistakes in multi-connector field installations?
The shroud on the TST-136-04-H-D is molded with a polarization key or asymmetric cavity that physically prevents a mating 72-pin ribbon cable connector from being inserted in the reverse orientation, eliminating a common wiring error in field-installed equipment. In industrial panels with 10 or more identical connectors, shrouded headers reduce costly reverse-polarity damage to sensitive logic circuits operating at 3.3 V or 5 V supply rails.
For a 72-pin parallel data bus design, how does TST-136-04-H-D compare to using multiple smaller connectors?
Using a single TST-136-04-H-D with 72 positions at 0.100 inch pitch consolidates the entire parallel bus into one connector footprint, reducing board area compared to three separate 24-pin connectors and eliminating inter-connector synchronization risks. A single 72-pin shrouded header also simplifies cable management, reducing harness length by roughly 30% versus distributing the same signal count across multiple smaller connectors in industrial data acquisition systems.
Which ribbon cable and IDC connector systems are mechanically compatible with the TST-136-04-H-D header?
The TST-136-04-H-D is compatible with standard 0.100 inch pitch IDC (insulation displacement contact) ribbon cable connectors and mass-termination connectors designed for 72-way or wider flat cables. Cable assemblies using 36-pair flat ribbon at 28 AWG or 26 AWG wire gauge mate securely to the 72-pin high-profile contacts, supporting data rates up to 100 MHz for parallel bus interfaces in embedded control and test equipment.
What inventory and lead time considerations matter when sourcing TST-136-04-H-D for a production build?
TST-136-04-H-D is a standard SAMTEC catalog connector available through authorized distributors with typical lead times of 4 to 8 weeks for volume orders. Buyers sourcing quantities above 500 units should confirm stock levels with multiple distributors and consider ordering safety stock, as 72-pin shrouded headers in high-profile configurations may have lower distribution inventory than smaller standard 2x20 formats. SAMTEC's factory direct program also offers accelerated lead times for custom or modified versions of the 0.100 inch pitch TST series.
