Applications
The S2M-128-01-L-D is used in custom cable harness assemblies for industrial robotics, defense electronics, medical equipment, and embedded computing systems requiring 56 individually routed wires at a 2.00 mm pitch. Its Tiger Eye contact system provides positive retention and reliable engagement in vibration-prone environments such as motor drives and vehicle control modules. The discrete wire socket style enables field-configurable harnesses where each of the 56 signal positions can be wired independently to match system topology.

Frequently Asked Questions
How many positions does the S2M-128-01-L-D provide and how are they arranged within the connector body?
The S2M-128-01-L-D is a 56-position connector organized in a dual-row layout with 28 contacts per row on a 2.00 mm pitch. This configuration accommodates up to 56 individually crimped discrete wires, making it suitable for complex cable harness assemblies in industrial automation, embedded computing, and defense systems where independent signal routing is required for each conductor.
What makes SAMTEC's Tiger Eye system on the S2M-128-01-L-D suited for high-reliability applications?
The Tiger Eye contact system uses a dual-beam contact design that applies increased normal force on the mating pin, maintaining low contact resistance even after thousands of mating cycles or exposure to vibration. For a 56-position socket at 2.00 mm pitch, this reliability is critical in applications like flight control harnesses, industrial robot cabling, and medical device interconnects where intermittent connections are unacceptable.
How does the discrete wire termination style of the S2M-128-01-L-D compare to mass-displacement ribbon cable connectors?
The S2M-128-01-L-D's discrete wire termination accepts individually crimped conductors in each of its 56 positions, allowing engineers to select wire gauge, insulation material, and routing path independently for every signal. This is distinct from mass-displacement IDC connectors that lock all conductors into a fixed flat-cable geometry at 1.27 mm or 2.54 mm pitch, limiting routing flexibility in harnesses traversing complex mechanical assemblies.
What wire gauges and cable types are compatible with the S2M-128-01-L-D's discrete wire crimp contacts?
SAMTEC discrete wire sockets at 2.00 mm pitch such as the S2M-128-01-L-D are typically compatible with 22 AWG to 28 AWG wire gauges when using the corresponding SAMTEC crimp contacts rated for that pitch. Suitable wire types include standard PVC-insulated hookup wire, PTFE-insulated aerospace wire, and silicone-jacketed conductors, enabling the 56-position harness to meet temperature ratings from -40°C to +105°C or higher depending on insulation selection.
