Frequently Asked Questions
Why is the shrouded design of TST-113-03-G-D preferred over open-frame headers in field-wiring applications?
The shroud on TST-113-03-G-D mechanically keys the mating connector to prevent mis-insertion, which is critical in field-wiring applications where technicians may assemble connectors without visual guidance. The housing walls also protect the 26 male contacts from physical damage and accidental shorts during cable handling, improving reliability compared to open-frame 0.100" headers.
What is the contact material and finish specification of TST-113-03-G-D and how does it influence connector longevity?
TST-113-03-G-D uses phosphor bronze contacts plated with 10 microinch gold over 50 microinch nickel. Gold plating provides low contact resistance below 20 milliohms and resistance to oxidation, while the nickel barrier prevents copper diffusion. This finish supports 500 or more mating cycles, making it appropriate for test fixtures and frequently disconnected I/O interfaces.
What ribbon cable or socket housing families mate with TST-113-03-G-D to form a complete 26-pin interconnect assembly?
TST-113-03-G-D mates with standard 0.100" pitch IDC ribbon cable connectors such as SAMTEC IDSS or IDSD series, as well as crimp-style discrete wire housings on a 2.54 mm grid. The dual-row 26-pin configuration accommodates a standard 26-conductor flat ribbon cable, enabling quick-disconnect wiring for sensor arrays, relay boards, or control signal interfaces with up to 26 independent channels.
