Frequently Asked Questions
What is the contact pitch and row configuration of the TST-104-04-S-D connector?
The TST-104-04-S-D features a 0.100 inch (2.54 mm) contact pitch in a dual-row arrangement providing 8 total positions (4 positions per row), making it a standard footprint compatible with a wide range of 0.100 inch pitch mating receptacles and IDC cable connectors.
How does the shroud on TST-104-04-S-D prevent assembly errors on a PCB?
The integrated polarizing shroud surrounds all 8 pins and includes a keying feature that physically blocks misaligned or reversed mating of the receptacle, reducing the risk of incorrect connections in production environments and ensuring consistent 2-row alignment every time.
What current and voltage ratings does a typical SAMTEC TST-series shrouded header support?
SAMTEC TST-series shrouded headers are typically rated for up to 3 A per contact and 250 V AC/DC working voltage, making them suitable for power and signal distribution applications in industrial and embedded systems operating within standard PCB assembly environments.
In which PCB assembly scenarios is TST-104-04-S-D preferred over surface-mount connectors?
The through-hole termination of TST-104-04-S-D provides superior mechanical strength compared to surface-mount alternatives, making it the preferred choice in applications subject to repeated mating cycles, vibration, or cable pull forces, such as robotics controllers, motor drive boards, and field-replaceable module interfaces.
