What are the key features of TST-136-04-L-D?
- 72-position dual-row shrouded header on 0.100" (2.54 mm) pitch for reliable high-signal-count connections
- Polarized shroud prevents mis-mating and provides mechanical keying for reliable cable-to-board assembly
- Through-hole mounting with 0.025" square posts offers strong PCB retention suitable for industrial environments
What is TST-136-04-L-D used for?
The TST-136-04-L-D is well suited for backplane interconnects, industrial control panels, and embedded computing systems requiring a high pin count (72 positions) at the standard 0.100" pitch. Its shrouded design simplifies cable assembly and prevents incorrect insertion, making it a reliable choice for field-serviceable equipment and test jigs where correct mating orientation is critical.

Frequently Asked Questions
What is the total position count and row configuration of the TST-136-04-L-D?
The TST-136-04-L-D provides 72 positions arranged in a dual-row configuration at a 0.100" (2.54 mm) pitch, giving 36 contacts per row. This standard pitch makes it directly compatible with a wide range of 0.100" IDC ribbon cable connectors and matching receptacle housings.
How does the shrouded design of the TST-136-04-L-D help in high-volume production environments?
The polarized shroud on the TST-136-04-L-D physically prevents a 72-position ribbon cable connector from being inserted backwards or offset by 1 row, reducing assembly errors in high-volume production lines. This keying feature eliminates costly board damage and field failures, improving overall manufacturing yield significantly.
When should a designer choose the TST-136-04-L-D over an equivalent unshrouded header for a 72-position interface?
Designers should choose the TST-136-04-L-D when the application demands foolproof mating, such as field-serviceable industrial equipment or test fixtures where different technicians mate the 72-position connector repeatedly. The shroud adds approximately 2 mm to the overall height but eliminates reverse-insertion risk across all 72 pins, which is critical for protecting sensitive FPGA or DSP boards.
