Applications
The HTSS-120-01-LM-DV is used in industrial control backplanes, mil-spec electronics, and high-reliability embedded systems where 40-position cable-to-board connections must function continuously at temperatures up to 125°C. Its large 2.15 inch body accommodates dual-row dual-column signal and power routing in equipment such as motor drive controllers, railway signaling systems, and avionics test fixtures. Engineers select this terminal strip for applications combining high pin count with cable mate flexibility while maintaining connector integrity under mechanical stress and thermal cycling.

Frequently Asked Questions
What is the body length and contact pitch of HTSS-120-01-LM-DV, and how many signal connections does it support?
HTSS-120-01-LM-DV has a body length of 2.15 inches with a 0.100 inch (2.54 mm) contact pitch, providing 40 positions in a dual-row rectangular arrangement. This supports up to 40 independent signal or power connections in a single connector, consolidating wiring from cable assemblies and reducing board-side connector count in high-pin-count industrial applications rated to 125°C.
How does the high-temperature rating of HTSS-120-01-LM-DV expand its usability compared to standard 85°C rated terminal strips?
Standard 0.100 inch terminal strips rated to 85°C can warp or lose contact retention force in applications with sustained ambient temperatures from 100°C to 125°C. The HTSS-120-01-LM-DV's high-temperature housing maintains its 2.15 inch body geometry and mating force specification across the full -55°C to 125°C range, preventing intermittent contacts in automotive ECUs, industrial ovens, and avionics bays that regularly exceed 85°C operating limits.
Which cable assembly configurations mate with HTSS-120-01-LM-DV for a complete 40-position cable-to-board solution?
SAMTEC HTSD and HTSC series cable connectors on 0.100 inch pitch mate directly with HTSS-120-01-LM-DV, available in ribbon cable and discrete 28 AWG to 22 AWG wire configurations. Each contact position is rated at up to 3 A, giving the full 40-position interface a combined capacity of up to 120 A distributed across signal and power contacts at a working voltage of 250 V in mixed signal and low-power supply applications.
In what ways does the polarized shroud of HTSS-120-01-LM-DV reduce assembly defects in manufacturing environments?
The shroud keying on HTSS-120-01-LM-DV prevents the mating cable connector from being inserted in reverse or offset by one row across the 40-position array. This eliminates a common source of board damage from reversed power or differential signal pairs, which is critical in automated assembly lines processing hundreds of cable harness installations per shift. The shroud also physically protects the 40 male contacts from bent-pin damage during connector shipping and pre-assembly handling.
