What are the key features of TST-112-03-L-D?
- 24-position dual-row shrouded header at 0.100 inch (2.54 mm) pitch with 1.5 inch body length for standard 24-pin IDC ribbon cable compatibility
- Phosphor bronze contacts with 10 microinch gold over 50 microinch nickel mating finish deliver reliable low-resistance connections and good spring retention
- Shrouded low-profile (L) housing provides mechanical polarization and pin protection while minimizing vertical clearance above the PCB
What is TST-112-03-L-D used for?
The TST-112-03-L-D is suited for industrial automation controllers, embedded computing I/O boards, and sensor interface modules that require a compact 24-pin shrouded header with low vertical clearance. Its low-profile shroud design is beneficial in enclosures with tight lid-to-board spacing, while the standard 0.100 inch pitch enables direct mating with off-the-shelf 24-pin IDC cable assemblies. The phosphor bronze contact material provides reliable spring force for consistent electrical contact across thousands of mating cycles.

Frequently Asked Questions
What contact material and plating specification does the TST-112-03-L-D use, and why does it matter?
The TST-112-03-L-D uses phosphor bronze contacts plated with 10 microinches of gold over 50 microinches of nickel on the mating surface. Phosphor bronze provides higher spring force than brass, maintaining reliable contact pressure after repeated mating cycles, while the gold plating keeps contact resistance below 20 milliohms and resists corrosion in humid industrial environments.
What advantage does the low-profile shroud of TST-112-03-L-D offer in compact enclosure designs?
The low-profile (L) shrouded housing of the TST-112-03-L-D reduces the connector's overall height above the PCB compared to standard-height shrouded headers, allowing installation in enclosures with vertical clearance as low as 8.5 mm. This makes it a practical choice for panel-mount industrial controllers, HMI boards, and embedded systems where board-to-lid spacing is constrained.
Can the TST-112-03-L-D mate with standard 24-conductor ribbon cable assemblies?
Yes, the TST-112-03-L-D is fully compatible with standard 24-conductor IDC ribbon cable assemblies terminated with 0.100 inch pitch dual-row sockets. Its 1.5 inch body length and rectangular pin pattern conform to industry standard 24-pin IDC header dimensions, allowing drop-in replacement with any compliant cable assembly in automation, data acquisition, or embedded I/O applications.
