What are the key features of TSM-142-04-TM-DV-P-TR?
- 84-position dual-row SMT terminal strip at 0.100 inch (2.54 mm) pitch supporting high-count signal and power interconnects on standard grid PCB layouts
- TM (top mount) surface mount style with DV dual-row configuration and P polarization key preventing incorrect mating orientation during assembly or field service
- Tape-and-reel (TR) packaging with 0.100 inch industry-standard pitch enabling compatibility with legacy through-hole footprints converted to surface mount designs
What is TSM-142-04-TM-DV-P-TR used for?
The TSM-142-04-TM-DV-P-TR is used in industrial control boards, PLC expansion modules, and embedded computing systems where 84 signals on a 0.100 inch grid must be routed between a baseboard and a pluggable daughtercard. The polarized dual-row design ensures correct connector orientation in field-replaceable module applications, making it well-suited for power distribution and mixed signal backplane interfaces.

Frequently Asked Questions
How many positions and at what pitch does the TSM-142-04-TM-DV-P-TR provide connectivity?
The TSM-142-04-TM-DV-P-TR provides 84 positions in a dual-row layout at 0.100 inch (2.54 mm) pitch, yielding 42 positions per row. This standard 0.100 inch grid is compatible with a wide range of legacy PCB layouts and mating headers, making it straightforward to source matching connectors and design compliant footprints in standard PCB CAD libraries.
For a PLC expansion module requiring field-replaceable daughterboards, how does the P polarization option on the TSM-142-04-TM-DV-P-TR reduce assembly errors?
The P polarization key physically prevents the 84-position dual-row connector from being inserted in the wrong orientation, eliminating the risk of connecting power pins to signal pins or reversing a 42-pin data bus in field service. In a PLC environment where technicians may replace modules without schematic reference, this mechanical keying reduces the risk of board damage from reversed connections across all 84 positions.
Is the TSM-142-04-TM-DV-P-TR compatible with legacy through-hole 0.100 inch headers, and what does that mean for board redesign?
Yes, the 0.100 inch (2.54 mm) pitch of the TSM-142-04-TM-DV-P-TR matches the industry-standard through-hole 0.100 inch grid, so it can mate with existing through-hole headers using the same 84-position dual-row footprint pitch. Engineers redesigning boards from through-hole to surface mount can keep the same mating header and only update the connector land pattern, avoiding the need to reroute the 84-pin signal bus or redesign the mating daughtercard.
