What are the key features of TST-113-02-F-D?
- 26-position dual-row shrouded header on 0.100 inch (2.54 mm) pitch delivering 26 signal paths in a 1.6 inch body length
- Phosphor bronze contacts with gold flash over nickel (50 microinch minimum) mating surface for reliable low-resistance connection
- Tin-over-nickel solder termination with nickel barrier prevents tin whisker migration and ensures robust through-hole solder joints
What is TST-113-02-F-D used for?
The TST-113-02-F-D is used in industrial automation panels, embedded control systems, and laboratory test fixtures requiring 26-signal board-to-cable harness connections on the standard 0.100 inch pitch. The polarizing shroud eliminates reversed-insertion errors in field wiring environments where technicians connect cables without visual access to polarity markers. Phosphor bronze contacts provide the spring-force consistency needed for stable electrical performance in vibrating machinery and temperature-cycling industrial enclosures.

Frequently Asked Questions
What contact material and mating finish are used in the TST-113-02-F-D, and why does that choice matter for contact reliability?
The TST-113-02-F-D uses phosphor bronze contacts with a gold flash over nickel mating finish, where the nickel layer is at least 50 microinches thick. Phosphor bronze delivers the consistent spring force needed to maintain low contact resistance across the connector's rated mating cycles, while the gold flash layer prevents oxidation that would increase resistance over time.
For a 26-signal industrial cable harness, how does the shroud on TST-113-02-F-D improve field wiring reliability compared to an open pin header?
The TST-113-02-F-D shroud surrounds all 26 contacts on the 0.100 inch (2.54 mm) pitch dual-row pattern and includes a polarizing key that allows mating only in the correct orientation. This prevents reversed-polarity wiring errors that could damage powered electronics, and the shroud also protects the contacts from physical damage when cables are disconnected and reconnected in tight enclosures or during equipment maintenance.
Why is the tin-over-nickel termination finish on the TST-113-02-F-D recommended for through-hole solder joints in industrial environments?
The tin-over-nickel termination on the TST-113-02-F-D includes a nickel barrier layer that blocks tin diffusion into the phosphor bronze contact base, which prevents the base-metal embrittlement and solder-joint cracking that can occur after repeated thermal cycling between -40°C and 85°C. This makes the solder joints more durable in industrial motor drives, automation controllers, and power supply boards subject to wide temperature swings.
