What are the key features of TSM-135-04-TM-SH-A?
- 70-position dual-row surface mount design at 0.100 inch (2.54 mm) pitch with top-mount horizontal mating interface enables right-angle cable routing parallel to the PCB surface
- Shrouded housing (SH suffix) provides positive contact polarization and physical protection for 70 contacts during repeated cable mating and unmating operations
- Top-mount (TM) SMT footprint allows placement on the PCB top side with horizontal cable exit, minimizing overall assembly height in space-constrained enclosures
What is TSM-135-04-TM-SH-A used for?
The TSM-135-04-TM-SH-A is suited for industrial automation controllers, embedded single-board computers, and robotics drive modules where a 70-position 0.100 inch pitch shrouded connector routes flat or ribbon cables horizontally across the PCB. Its top-mount SMT design eliminates through-hole drilling while the shroud ensures correct orientation during repeated cable attachment in maintenance environments. PLC expansion modules and motion control cards use this connector family to interconnect I/O boards, sensor harnesses, and actuator drive cables in compact panel assemblies.

Frequently Asked Questions
How does the top-mount orientation of TSM-135-04-TM-SH-A differ from a standard vertical surface mount header for horizontal cable routing?
The top-mount (TM) orientation positions the mating opening on the top face of the connector body so cables exit horizontally parallel to the PCB at heights below 8 mm above the board, whereas a vertical SMT header exits cables perpendicular to the PCB and adds 12 mm or more of vertical height. For rack systems and flat-panel enclosures with 70-position ribbon cables and clearances under 10 mm, the top-mount design is the only viable SMT option.
What ribbon or flat cable configuration mates correctly with the 70-position TSM-135-04-TM-SH-A at 0.100 inch pitch?
TSM-135-04-TM-SH-A mates with standard 70-conductor IDC or crimp-style sockets at 0.100 inch pitch, corresponding to a 70-way flat cable approximately 3.5 inches (88.9 mm) wide at 0.050 inch conductor spacing. Both 28 AWG and 30 AWG conductors in standard flat cable are compatible, supporting signal currents up to 1 A per conductor at typical industrial control voltage levels of 5 V to 24 V DC.
For an industrial I/O expansion board requiring 64 signal lines and 6 power/ground pins, how does TSM-135-04-TM-SH-A compare to using two 36-position connectors?
A single TSM-135-04-TM-SH-A covers all 70 required positions in one connector spanning roughly 3.5 inches at 0.100 inch pitch, eliminating the PCB routing complexity and additional 3.6-inch footprint of a second 36-position connector. One connector also means one cable assembly and one mating operation, reducing field service time and the risk of a connector being accidentally omitted or swapped during 70-way signal bus maintenance.
