Frequently Asked Questions
What are the pitch and position count of the TST-102-05-T-D, and which mating connectors are compatible?
The TST-102-05-T-D is a 4-position dual-row header with 2.54 mm (0.100 inch) pitch. It mates with standard 0.1 inch pitch IDC socket housings and discrete wire connectors, providing a secure 4-pin interface for embedded and industrial applications.
How does the shroud on TST-102-05-T-D improve assembly reliability?
The polarized shroud on the TST-102-05-T-D physically prevents a mating connector from being inserted upside-down or offset by 1 row, eliminating mis-mating errors in production. This is particularly valuable in high-volume automated cable assembly where a 2.54 mm pitch 4-pin connector must be inserted correctly every time.
What current rating does each contact in the TST-102-05-T-D support?
Each contact in the TST-102-05-T-D is rated at up to 3A, allowing the 4-position header to carry both signal lines and low-power supply rails on a single connector. This makes it suitable for sensor modules and small actuator interfaces that draw under 3A per pin.
In what scenarios would TST-102-05-T-D be chosen over a non-shrouded header?
TST-102-05-T-D is preferred in field-serviceable equipment and prototyping boards where inexperienced users might accidentally reverse a connector. The shroud adds less than 3 mm to overall connector height while eliminating the possibility of reverse insertion that could damage a 3.3 V or 5 V powered circuit.
