What are the key features of TST-112-05-G-D?

  • 24-position dual-row shrouded header with 0.100" (2.54 mm) pitch providing polarized, keyed mating for error-free connector insertion
  • Protective plastic shroud prevents mis-mating and shields contacts from accidental damage during board assembly and field servicing
  • Gold-plated contacts maintain low contact resistance for reliable signal transmission in industrial and embedded computing applications

What is TST-112-05-G-D used for?

The TST-112-05-G-D is suited for embedded computing boards, industrial control panels, and prototype development platforms requiring 24-pin polarized board interconnects. Its 0.100" pitch through-hole design is compatible with standard IDC ribbon cable assemblies, making it a practical choice for signal distribution between PCBs. The shrouded housing ensures correct cable orientation, reducing wiring errors in field-installed equipment.

Frequently Asked Questions

How does the shroud on the TST-112-05-G-D improve reliability compared to an unshrouded 24-pin header?

The TST-112-05-G-D includes a protective plastic shroud that aligns and keys the mating connector, preventing reverse or offset insertion across all 24 positions. This polarization feature eliminates a common source of field failures where unshrouded headers can be plugged in backwards, potentially damaging 24 signal lines or connected ICs. The shroud also protects gold-plated contacts from mechanical damage during assembly at 0.100" (2.54 mm) pitch.

Which cable assemblies are compatible with the TST-112-05-G-D 24-position header?

The TST-112-05-G-D is designed to mate with standard 24-conductor IDC ribbon cable assemblies terminating in a matching 24-position female connector on 0.100" (2.54 mm) pitch. It also accepts discrete wire housings using 22 to 28 AWG conductors, covering a wide range of current capacities up to approximately 1 A per contact. This compatibility with widely available cable assemblies reduces BOM complexity in industrial and embedded system designs.

When should an engineer choose the TST-112-05-G-D over a 0.050" pitch surface-mount alternative for a 24-signal interface?

The TST-112-05-G-D on 0.100" (2.54 mm) pitch is preferable when field serviceability is required, since technicians can easily mate and unmate the connector without precision tools. Through-hole mounting provides stronger mechanical retention than surface-mount pads, withstanding pull-out forces that can stress SMT joints on high-vibration equipment. For designs where technicians must swap ribbon cables frequently, the 0.100" pitch also accommodates standard IDC tools, reducing the risk of contact damage compared to 0.050" pitch alternatives.
