What are the key features of TSM-142-03-SS-DV-P-TR?
- 84-position dual-row 2x42 layout at 0.100" (2.54 mm) pitch provides broad signal coverage for backplane and multi-bus PCB interconnect designs
- Dual-voltage (DV) contact configuration supports mixed-voltage board designs, accommodating both 3.3 V and 5 V signal levels on a single connector
- Polarization (P) feature prevents reverse mating of the 84-pin connector, eliminating pin reversal faults during assembly and field maintenance
What is TSM-142-03-SS-DV-P-TR used for?
The TSM-142-03-SS-DV-P-TR is designed for high-density backplane connector, system bus, and expansion card applications in industrial computers, PLC systems, and communications equipment where 84 positions at 0.100" pitch are required. Its dual-voltage capability and polarization key make it well-suited for mixed 3.3 V / 5 V digital systems and production-line installations requiring fail-safe, keyed mating across all 84 signal and power lines.

Frequently Asked Questions
What is the total pin count and contact pitch of TSM-142-03-SS-DV-P-TR for backplane connector designs?
The TSM-142-03-SS-DV-P-TR provides 84 total positions in a dual-row 2x42 configuration at 0.100" (2.54 mm) pitch. This standard pitch makes it compatible with a wide range of backplane and through-hole mating headers while providing 84 independent signal or power lines for bus interconnect applications.
What does dual-voltage (DV) mean in TSM-142-03-SS-DV-P-TR and which mixed-voltage systems benefit from it?
The dual-voltage (DV) designation in TSM-142-03-SS-DV-P-TR indicates that the connector supports two different voltage domains—typically 3.3 V and 5 V—within the same 84-position housing. This benefits mixed-logic industrial PCBs, legacy PLC expansion cards, and embedded systems that transition between older 5 V TTL logic and modern 3.3 V CMOS logic on a single board interconnect.
How does the polarization feature of TSM-142-03-SS-DV-P-TR reduce field maintenance errors compared to unpolarized 84-pin connectors?
The polarization (P) key in TSM-142-03-SS-DV-P-TR physically blocks incorrect 180-degree insertion across all 84 pins, preventing catastrophic reverse-polarity events during field board swaps. In industrial systems with 42 dual-row positions of mixed power and signal lines, a single misalignment could damage multiple ICs, making this keying feature essential for maintenance-intensive deployments.
