Applications
The HTSS-122-01-L-DV is designed for industrial control boards, embedded computing systems, and motor drive platforms requiring a protected 44-pin wire-to-board interface at 0.100 inch pitch with high-temperature capability. Its dual-voltage feature allows routing of multiple supply rails and signal lines through a single keyed connector, reducing harness complexity in 3.3 V, 5 V, and 12 V mixed-voltage systems. The shrouded housing and gold mating contacts make it suited for field-serviceable equipment that is frequently connected and disconnected by technicians.

Frequently Asked Questions
How does the HTSS-122-01-L-DV differ from the HTSS-122-01-LM-DV in physical configuration and application fit?
The HTSS-122-01-L-DV is a standard version of the 44-position HTSS-122 series with a single mounting orientation, while the HTSS-122-01-LM-DV adds a mid-mount or modified mounting configuration. Both use the same 0.100 inch (2.54 mm) pitch, dual-voltage layout, and 44 contact positions, so they share the same cable mate compatibility. The choice between them depends on PCB layout constraints: the L-DV fits standard vertical connector mounting while the LM-DV is used where the connector height or board-edge clearance requires an alternate mechanical profile.
What current rating and wire gauge is the HTSS-122-01-L-DV designed to handle across its 44 contacts?
SAMTEC HTSS series 0.100 inch pitch connectors with square-pin contacts are typically rated for 3 A per contact at 30 VAC/DC for signal lines, depending on the wire gauge and ambient temperature. At the standard 0.100 inch (2.54 mm) pitch with 44 positions, using 26 AWG to 28 AWG wire in the mating cable harness is typical for signal applications, while power contacts may use 22 AWG to 24 AWG wire to carry higher currents. Designers should derate contact current above 70°C ambient to prevent thermal damage to the connector housing.
Why is the high-temperature shroud of the HTSS-122-01-L-DV important for industrial control PCB applications?
Industrial control boards in motor drives, PLCs, and HVAC controllers can reach ambient temperatures of 85°C or higher near power transistors and heat sinks, which would soften or deform standard nylon connector housings rated only to 70°C. The high-temperature shroud of the HTSS-122-01-L-DV uses a glass-filled thermoplastic housing material that maintains dimensional stability and contact alignment at elevated temperatures, preventing intermittent connections caused by housing deformation. This makes it suitable for safety-critical control wiring where connection reliability must be maintained throughout a wide operating temperature range.
How does the dual-voltage configuration of the HTSS-122-01-L-DV simplify cable harness design in mixed-rail embedded systems?
The dual-voltage (DV) configuration of the HTSS-122-01-L-DV uses a divided shroud or keying arrangement that allows the 44 positions to be allocated across two voltage domains within a single connector body, preventing cross-domain mating errors during field installation. This means a single harness connector carrying both 5 V logic signals and 12 V power lines can be plugged into the HTSS-122-01-L-DV without risk of mis-routing a 12 V wire into a 3.3 V signal position. The polarized dual-voltage design reduces the number of separate connectors needed on the PCB, saving board space and reducing cable assembly labor costs.
