Key Features
- 26-position dual-row SMT terminal strip at 0.100" (2.54 mm) pitch providing reliable surface-mount board-to-cable connectivity in standard form factor
- Shielded housing (SH suffix) delivering EMI attenuation for noise-sensitive 26-signal interfaces in mixed-signal PCB environments
- Press-fit mounting tabs (P suffix) providing mechanical retention during reflow soldering to prevent connector shifting before solder joints solidify
- Tape-and-reel (TR) packaging supporting automated pick-and-place assembly for high-volume production with placement rates above 8,000 units per hour
Applications
The TSM-126-05-T-SH-P-TR is widely used in industrial automation control boards, embedded single-board computers, and communication modules where 26 signals must be reliably connected via surface-mount terminal strips with EMI shielding. Its shielded vertical SMT design is particularly effective in mixed-signal environments such as motor drive control boards and data acquisition systems where digital noise could otherwise couple into adjacent analog measurement channels. The tape-and-reel format and press-fit stabilization tabs streamline high-volume PCB manufacturing by ensuring precise placement and stability throughout the reflow oven cycle.

Frequently Asked Questions
How does the press-fit retention feature on TSM-126-05-T-SH-P-TR improve SMT assembly yield in reflow processing?
The P-suffix press-fit mounting tabs on the TSM-126-05-T-SH-P-TR mechanically anchor the 26-position connector to the PCB before soldering, preventing the connector from shifting when the board passes through the reflow oven at peak temperatures of 260°C. Without this retention, connector movement during reflow can cause up to 0.3 mm misalignment, which at 0.100" pitch would bridge adjacent pads and create solder shorts across multiple signal pins, significantly reducing first-pass yield.
For a 26-signal bus interface, how does the shielded TSM-126-05-T-SH-P-TR reduce crosstalk compared to unshielded alternatives?
The SH-suffix shielded housing on the TSM-126-05-T-SH-P-TR provides a grounded metal enclosure around the 26-position contact array, reducing inter-connector electromagnetic crosstalk by approximately 15 to 25 dB in the 50 MHz to 500 MHz frequency range where modern digital bus signals have their dominant switching harmonics. This shielding is critical on boards where the TSM connector sits within 10 mm of wireless antenna traces, RF amplifier inputs, or high-precision ADC front-end circuits.
Which signal types are best suited for the 26-position TSM-126-05-T-SH-P-TR connector in industrial PCB designs?
The TSM-126-05-T-SH-P-TR at 0.100" pitch and 26 positions is well-matched to parallel bus interfaces carrying GPIO signals, low-speed SPI or I2C buses, and mixed power-and-signal configurations where up to 3 A per contact can be allocated across the 26-position array. It is commonly used in PLC input/output expansion modules, motor encoder feedback boards, and industrial sensor hubs where 26 discrete signals must be routed to a panel-mounted cable harness.
When would TSM-126-05-T-SH-P-TR be specified over a non-shielded TSM-126 variant in a PCB design review?
The shielded TSM-126-05-T-SH-P-TR is specified over non-shielded TSM variants when pre-compliance EMC testing reveals that radiated emissions through the 26-pin connector interface exceed EN 55032 Class B limits, typically above 150 MHz in the frequency band where cable harnesses connected to the terminal strip act as efficient radiating antennas. Adding the SH shielded version can reduce radiated emissions through the connector by 10 to 20 dB without requiring board-level redesign, avoiding costly PCB respins.
