What are the key features of TST-104-04-T-D?
- 8-position dual-row configuration on 0.100" (2.54 mm) pitch providing 4 contacts per row in a compact shrouded PCB header body
- Full polarizing shroud prevents mismating with cable-side connectors during assembly and field servicing of wire harnesses
- Through-hole termination ensures robust mechanical retention and solder joint reliability in vibration-prone industrial and embedded applications
- Compatible with standard 0.100" pitch IDC ribbon cable assemblies enabling low-cost and high-volume wire-to-board connections
What is TST-104-04-T-D used for?
TST-104-04-T-D is a standard choice for wire-to-board connections in embedded control boards, industrial I/O panels, and development systems where 8 signals must be routed reliably between a PCB and an external cable harness. Its shrouded 0.100" pitch header mates with common IDC ribbon cable assemblies used in robotics controllers, PLC expansion modules, and sensor interface boards. The through-hole construction provides the mechanical robustness needed for connectors subject to repeated cable mating cycles in test fixtures and field-serviceable equipment.

Frequently Asked Questions
How many signal positions does TST-104-04-T-D provide and how are they arranged?
TST-104-04-T-D is an 8-position shrouded PCB header arranged in 2 rows of 4 contacts on a 0.100" (2.54 mm) pitch, providing a compact dual-row footprint that mates with standard IDC ribbon cable connectors and discrete wire housings in the same pitch family.
What benefit does the shroud on TST-104-04-T-D provide compared to unshrouded pin headers?
The full shroud around all 8 contacts provides a mechanical polarizing key that prevents cable-side connectors from being inserted backwards or offset, reducing mismating and potential damage to adjacent components during harness assembly and field maintenance operations.
In which industrial or embedded applications is TST-104-04-T-D a typical board-to-cable solution?
TST-104-04-T-D is widely used in PLC expansion modules, robotics sensor interfaces, UART/SPI programming headers, and 8-channel I/O harness connections where 8 signals at 0.100" pitch need to transfer reliably between a PCB and an external cable without risk of connector mis-orientation.
What current rating per contact should be assumed when selecting TST-104-04-T-D for mixed power and signal wiring?
Standard 0.100" pitch through-hole headers in the Samtec TST series are rated at approximately 3 A per contact on signal pins, so for a mixed power-and-signal harness the designer should verify that power contacts do not exceed this limit while keeping total connector body temperature within the 105°C housing rating.
