Key Features
- 14-position dual-row 0.100" (2.54 mm) pitch SMT terminal strip with dual-height (DH) body option for varying mating stack heights
- Keyed (K) connector design prevents mis-insertion and reverse mating in multi-connector PCB environments with similar-sized connectors
- Tape-and-reel (TR) packaging enables high-volume automated pick-and-place assembly for production efficiency without manual loading
Applications
The TSM-107-03-SS-DH-A-K-TR is designed for board-to-board and board-to-cable applications in embedded systems, industrial automation, and test equipment where a 14-position keyed SMT connector prevents mis-mating during field installation or maintenance. Its dual-height body accommodates different mating connector stack heights, allowing flexible stacking configurations in chassis-constrained designs. The tape-and-reel format supports high-volume PCB assembly lines, making it a practical choice for consumer electronics and IoT device production runs.

Frequently Asked Questions
How does the keying feature (K) on the TSM-107-03-SS-DH-A-K-TR prevent field wiring errors during maintenance?
The TSM-107-03-SS-DH-A-K-TR's K keying option adds a physical polarization feature to the 14-position 0.100" (2.54 mm) pitch body that mechanically prevents a mating connector from being inserted in the wrong orientation or into an adjacent identical connector. This is particularly valuable in industrial panels where 4 or more similar-looking 14-pin connectors are mounted close together on the same PCB, eliminating wiring swap errors that could damage downstream circuits.
What does dual-height (DH) mean for the TSM-107-03-SS-DH-A-K-TR, and which stacking configurations benefit from this option?
The dual-height designation in the TSM-107-03-SS-DH-A-K-TR indicates the connector body has an extended insulator height compared to standard-height TSM variants, typically adding 2 mm to 4 mm to accommodate a larger air gap between mated PCBs. This extra height is beneficial in board-stacking applications where clearance is needed for tall components—such as capacitors or ferrite beads—on the lower board that would otherwise prevent the two PCBs from mating at standard stack height.
When is the TSM-107-03-SS-DH-A-K-TR a cost-effective alternative to board-to-board connectors with dedicated housing systems?
The TSM-107-03-SS-DH-A-K-TR is a lower-cost alternative to proprietary board-to-board connector systems when the design needs only 14 positions at 0.100" pitch and can accept a non-latching connection, since the TSM series relies on solder retention and contact friction rather than a dedicated locking housing. Using a standard 2.54 mm pitch SMT strip avoids the MOQ commitments and limited second-source options associated with proprietary mezzanine connector families.
