What are the key features of TSM-135-02-STL-DH-A-K-TR?
- 70 positions (35 per row) on 0.100" (2.54 mm) dual-row pitch for high-density signal interfaces
- Low-profile STL insulator reduces connector standoff height for space-critical PCB designs
- Keyed (K) alignment prevents incorrect orientation during mating
- Tape and reel (TR) packaging enables automated SMT pick-and-place production
- RoHS compliant construction with gold-plated contacts for reliable low-resistance connections
What is TSM-135-02-STL-DH-A-K-TR used for?
The TSM-135-02-STL-DH-A-K-TR is suited for high-density backplane interconnects, daughter-card interfaces, and embedded computing modules where 70 signals must be routed between PCBs on a compact 0.100" grid. Its low-profile insulator is particularly valued in slim enclosures or multi-board stack assemblies where minimizing the total stack height is a design constraint.

Frequently Asked Questions
How many signal positions does the TSM-135-02-STL-DH-A-K-TR support, and how are they distributed across the rows?
The connector provides 70 total positions arranged in a dual-row (2 × 35) layout on a 0.100" (2.54 mm) pitch. This is one of the larger TSM series configurations, making it ideal for interfaces requiring 70 simultaneous signal or power connections in a single compact PCB footprint.
What does the STL insulator designation indicate about the TSM-135-02-STL-DH-A-K-TR profile height?
STL denotes a short (low-profile) insulator body, which reduces the height of the connector above the PCB surface compared to standard or high-profile variants. This is critical in slim chassis or multi-card assemblies where total board stack height must stay within a defined limit, such as a 1U enclosure.
Does the keying feature on the TSM-135-02-STL-DH-A-K-TR help prevent wiring errors on 70-pin interfaces?
Yes, the K (keyed) feature introduces a mechanical polarization that prevents the mating connector from being inserted in the wrong orientation. On a 70-pin dual-row header this is essential, since an incorrect mating could apply wrong voltages to 35 or more signal lines simultaneously, risking circuit damage.
What is the lead time and packaging format for the TSM-135-02-STL-DH-A-K-TR when ordering for volume production?
The part is supplied in tape and reel (TR) format, which is compatible with standard SMT pick-and-place equipment for automated board assembly. For volume procurement, buyers should confirm current lead times with distributors, as 70-position connectors in low-profile variants may have limited stock compared to standard 2 × 20 or smaller counts.
