Key Features
- 54-position dual-row surface-mount terminal strip at 0.100" (2.54 mm) pitch for board-to-board and board-to-flex high pin-count connections
- Polarization (P suffix) feature prevents incorrect mating orientation, eliminating mismate errors in field-replaceable module assemblies
- Dual-height (DH) configuration supports two distinct PCB-to-PCB mating heights in the same connector series for flexible system design
- Tape-and-reel (TR) packaging enables automated pick-and-place SMT assembly at high production volumes with minimal handling
- Surface-mount termination eliminates through-hole drilling and simplifies multi-layer PCB fabrication for compact system boards
Applications
The TSM-127-02-TM-DH-A-P-TR serves high-density board-to-board interconnect applications in industrial computing, embedded systems, and telecommunications equipment requiring 54 positions at 0.100" pitch. Its polarization feature and dual-height design make it ideal for modular backplane systems where daughter cards must be inserted in the correct orientation to prevent damage. The tape-and-reel packaging facilitates automated SMT production in high-volume consumer and industrial electronics manufacturing environments.

Frequently Asked Questions
What does the 'P' suffix mean in TSM-127-02-TM-DH-A-P-TR and how does it prevent connector damage?
The 'P' suffix in TSM-127-02-TM-DH-A-P-TR denotes a polarization or post feature that physically prevents the connector from mating in the wrong orientation. This ensures that the 54-position, 0.100" pitch terminal strip can only engage with its mating header in the correct alignment, protecting sensitive circuits from reversed pin connections that could cause immediate damage or intermittent failures.
How many positions does the TSM-127-02-TM-DH-A-P-TR provide and what does its dual-row arrangement offer?
The TSM-127-02-TM-DH-A-P-TR provides 54 positions arranged in 2 rows of 27 contacts each at 0.100" (2.54 mm) pitch. The dual-row layout at standard 0.100" pitch is compatible with a wide range of mating SHF or similar headers, and provides sufficient pin density for mixed signal, power, ground, and control line assignments typical in embedded processor expansion board designs.
What does the dual-height (DH) designation mean for TSM-127-02-TM-DH-A-P-TR board stacking?
The dual-height (DH) designation indicates that the TSM-127-02-TM-DH-A-P-TR connector body is designed to support two mating height levels, typically accommodating PCB-to-PCB spacings such as 8.5 mm and 11.0 mm within the same connector family. This flexibility allows system designers to use the same PCB footprint while selecting the appropriate mating height for different module thicknesses in modular industrial or computing platforms.
Can TSM-127-02-TM-DH-A-P-TR be used in automated SMT production lines and what packaging is provided?
Yes, the TR suffix confirms the TSM-127-02-TM-DH-A-P-TR is supplied in tape-and-reel packaging, which is fully compatible with standard SMT pick-and-place equipment. Standard reel sizes typically contain 250 to 500 pieces, supporting continuous automated assembly at production rates suitable for high-volume PCB manufacturing with minimal operator intervention and reduced placement cycle times.
