What are the key features of TSM-124-05-TM-SH-A?
- 24-position dual-row 0.100" (2.54 mm) pitch SMT terminal strip with horizontal mating direction for space-constrained enclosure designs
- Shielded metal housing provides EMI attenuation and grounding for noise-sensitive analog or mixed-signal board connections
- Tin-plated contacts offer a cost-effective solution for applications requiring fewer than 50 mating cycles at signal currents up to 1 A per contact
What is TSM-124-05-TM-SH-A used for?
The TSM-124-05-TM-SH-A is suited for industrial automation panels, embedded controllers, and audio or analog instrumentation boards that need 24-pin shielded horizontal cable connections via SMT assembly. Its horizontal mating direction facilitates flat cable routing parallel to the PCB within shallow enclosures where vertical clearance is limited. The shielded housing also makes it a practical choice for mixed-signal designs where adjacent switching regulators or digital buses could otherwise inject noise into sensitive analog signal lines.

Frequently Asked Questions
How does the TM (tin-plated) contact finish on the TSM-124-05-TM-SH-A compare to a gold-plated version for a 24-pin interface?
The TM designation on the TSM-124-05-TM-SH-A indicates tin-plated contacts, which have a slightly higher initial contact resistance than gold-plated contacts but are adequate for signal levels above 100 mV and fewer than 50 mating cycles. Tin plating reduces the per-unit connector cost, making it preferable for high-volume production of consumer and industrial equipment where gold is not needed for signal integrity. For applications requiring very low contact resistance below 10 mΩ or more than 100 mating cycles, the gold-plated TSM-124-05-G-SH-A variant would be more appropriate.
In which applications does the SH shielded housing on the TSM-124-05-TM-SH-A provide a measurable benefit?
The shielded housing on the TSM-124-05-TM-SH-A is most beneficial in mixed-signal PCB designs where digital switching at 10 MHz or faster could couple noise into adjacent analog signal lines through the 24-pin connector. The metal shield provides a grounded barrier that attenuates electromagnetic interference, helping maintain signal fidelity in audio amplifier boards, sensor signal conditioning modules, and data acquisition front-ends. The shield grounds to the PCB via SMT tabs, creating a continuous low-impedance EMI return path at the 0.100" (2.54 mm) pitch footprint.
What cable types and AWG conductors are compatible with the TSM-124-05-TM-SH-A 24-position terminal strip?
The TSM-124-05-TM-SH-A is designed to accept 24-conductor flat ribbon cables or discrete wire housings on the 0.100" (2.54 mm) pitch, typically terminating 26 AWG or 28 AWG conductors. At 26 AWG, each contact can carry approximately 1 A of signal current, which covers most logic-level and low-power analog applications at 3.3 V, 5 V, or 12 V. The horizontal single-row mating interface allows the cable to exit parallel to the PCB surface, simplifying routing through side-panel cable entry points in rack-mount enclosures.
