What are the key features of TST-104-05-S-D?
- 8-position dual-row shrouded header at 2.54 mm (0.100 inch) pitch with 5 mm post length provides secure polarized cable-to-board connections with contact protection
- Shrouded housing blocks accidental contact shorting and forces correct mating orientation, eliminating reversed-connector assembly errors in 8-signal harnesses
- Through-hole (S) mounting with dual-row (D) layout delivers strong board retention suitable for applications with mechanical vibration or frequent cable mating cycles
What is TST-104-05-S-D used for?
The TST-104-05-S-D is used in control boards, sensor interface modules, and prototyping platforms that require a compact 8-signal wire-to-board connection with positive polarization. Its 2.54 mm pitch is compatible with standard IDC ribbon cables and discrete wire housings, making it easy to integrate into both machine-built and hand-wired harnesses. The shrouded design is particularly valuable in field-service scenarios where technicians must connect and disconnect cable assemblies without reference markings.

Frequently Asked Questions
What does the '05' suffix in TST-104-05-S-D specify about the connector's physical dimensions?
The '05' designates a 5 mm post length above the PCB surface. This 5 mm standoff determines the minimum housing depth of the mating cable connector and ensures adequate wire-to-board clearance for AWG 28 or AWG 26 ribbon cables connected to the 8-position header.
How does the shrouded housing on the TST-104-05-S-D reduce wiring errors in multi-connector PCB assemblies?
The shroud creates a keyed outer wall that only accepts the mating housing in one orientation, preventing the 180° pin-reversal that would cross-connect 8 signals. In sensor arrays or motor-drive boards where reversing even 1 pin can damage a 3.3 V logic input, this mechanical polarization is a critical fault-prevention feature.
What current rating can each pin in the TST-104-05-S-D typically handle for mixed power-and-signal harnesses?
At standard 2.54 mm pitch through-hole headers in the TST series, each contact typically supports 1 A at a 30°C temperature rise above ambient, with a maximum 3 A per pin for low-duty-cycle power connections on larger gauge wire. For an 8-position connector, this allows allocating 2 pins to 5 V power at 2 A total while keeping 6 pins for 3.3 V logic signals.
How does TST-104-05-S-D compare to an open, unshrouded header for PCB real-estate and signal protection?
The TST shrouded header occupies slightly more PCB area than an unshrouded 8-position header — approximately 10.16 mm × 10.16 mm versus 10.16 mm × 7.62 mm — but the shroud walls prevent adjacent metal objects from shorting the 8 exposed pins during cable installation, which is critical in field-service environments.
