Key Features
- 44 positions on 0.100 inch (2.54 mm) pitch providing high-density wire-to-board connectivity in a compact footprint
- High-temperature rated shrouded housing protecting contacts from debris, accidental shorts, and mis-mating
- Dual-voltage (DV) configuration enabling use in mixed-voltage wire harness applications on the same connector
- Polarized shroud design for foolproof, keyed mating with compatible cable assemblies and IDC connectors
- Cable-mate design compatible with standard 0.100 inch pitch ribbon cable and discrete wire harnesses
Applications
The HTSS-122-01-LM-DV is used in industrial control panels, robotics, test fixtures, and embedded computing boards that require high-density wire-to-board connections with protection against accidental mis-mating. Its 44-position, 0.100 inch pitch layout and dual-voltage capability make it suitable for applications routing multiple voltage rails and signals in a single harness connector. The high-temperature shroud allows use in industrial environments where elevated ambient temperatures, vibration, or contaminants are present.

Frequently Asked Questions
How does the 44-position dual-voltage configuration of the HTSS-122-01-LM-DV benefit mixed-signal cable harness designs?
The HTSS-122-01-LM-DV provides 44 positions on a 0.100 inch (2.54 mm) pitch in a dual-voltage configuration, allowing a single connector to carry multiple voltage rails and signal lines within one polarized harness. This eliminates the need for multiple separate connectors when routing both power and control signals, reducing harness complexity, connector count, and assembly time on industrial PCBs. The dual-voltage design also enables physical separation of high- and low-voltage circuits within the 44-pin field for improved isolation.
What mechanical protection does the high-temperature shroud of the HTSS-122-01-LM-DV offer during field installation and operation?
The shrouded housing of the HTSS-122-01-LM-DV encases all 44 contact positions, preventing accidental short circuits from tools, wire ends, or conductive debris during installation and operation. The shroud also provides a polarization key so the mating cable connector can only be inserted in the correct orientation, preventing reverse-polarity damage to voltage-sensitive circuits. In high-temperature environments, the housing material maintains dimensional stability and contact alignment above the 70°C limits typical of standard connectors.
Which wire gauges and cable types are compatible with the SAMTEC HTSS-122-01-LM-DV mating cable connectors?
The HTSS-122-01-LM-DV is designed as a cable mate for standard 0.100 inch (2.54 mm) pitch IDC ribbon cables and discrete wire harness assemblies, typically using 26 AWG to 28 AWG wire that fits the 0.100 inch contact spacing. SAMTEC offers compatible female IDC housings and crimp-terminated discrete wire connectors in the HTS series that mate directly with the HTSS-122 terminal strip. For applications requiring 22 AWG to 24 AWG heavier wire, designers should verify current rating and insulation displacement compatibility with the selected cable mate.
When should a designer choose the HTSS-122-01-LM-DV over a standard unshrouded 0.100-inch terminal strip for a 44-pin interface?
The shrouded HTSS-122-01-LM-DV is the better choice when the 44-pin interface will be mated and unmated in the field by technicians rather than only in controlled factory assembly, since the shroud and polarization key prevent dangerous mis-wiring. Unshrouded strips provide lower profile and easier access for PCB-level test probing but offer no mechanical protection or polarity enforcement. In industrial controllers, motor drives, and safety-critical embedded systems where wiring errors can damage 3.3 V or 5 V circuits, the shrouded connector is the safer and more serviceable choice.
