What are the key features of TST-112-04-L-D?
- 24-position dual-row shrouded header at 0.100" (2.54 mm) pitch with integrated polarization key preventing mis-mating in dense board interconnect applications
- Low-profile (L) through-hole termination optimized for compact vertical connector stacking heights without sacrificing PCB retention strength
- Dual-row (D) configuration doubling signal density versus single-row alternatives, accommodating 24 contacts within a standard 2.54 mm grid footprint
What is TST-112-04-L-D used for?
The TST-112-04-L-D is widely used in embedded computing, industrial automation, and consumer electronics for board-to-cable and board-to-board interconnects requiring polarized mating. The shrouded housing protects 24 dual-row contacts from accidental damage and ensures correct orientation during assembly and field servicing. Its 0.100" pitch and low-profile design make it suitable for compact PCB designs in data acquisition, motor control, and power distribution modules.

Frequently Asked Questions
What is the contact pitch, position count, and row configuration of the TST-112-04-L-D shrouded PCB header?
The TST-112-04-L-D is a 24-position dual-row shrouded header at 0.100" (2.54 mm) pitch, providing 12 contacts per row. The dual-row (D) design doubles the interconnect density versus a single-row 12-position header of the same PCB length, enabling simultaneous routing of 24 signals, power, and ground connections within a compact 2.54 mm grid-aligned footprint commonly used in embedded systems.
How does the shrouded housing on the TST-112-04-L-D prevent assembly errors during cable connection?
The shrouded housing of the TST-112-04-L-D encloses all 24 contact pins within a plastic frame that includes a polarization key and mechanical guide ribs. This prevents a mating IDC or ribbon cable connector from being inserted upside-down or offset by 2 positions, which would reverse signal and power assignments. The keyed shroud ensures correct pin-1 orientation every time, reducing field assembly errors in industrial control and embedded applications with 24-position cable harnesses.
What applications favor the TST-112-04-L-D low-profile variant over a standard-height shrouded header?
The low-profile (L) version of the TST-112-04-L-D reduces the above-board connector height, making it ideal for applications with tight chassis clearances or PCB stacking configurations where vertical space is limited to less than 10 mm. Typical use cases include flat-panel industrial displays, compact motor driver cards, and multi-board embedded systems where a standard-height 24-position shrouded header would obstruct adjacent components or prevent board-to-board stacking at 8 mm to 10 mm spacing.
