Key Features
- 70-position dual-row (2×35) Tiger Eye socket with 2.00 mm pitch provides independent contact wiping for reliable discrete wire-to-board connections at 3 A per pin
- High-reliability Tiger Eye contact design delivers multiple wipe points per pin, reducing contact resistance and maintaining connection integrity in vibration-prone environments up to +125°C
- Crimp-style discrete wire termination accommodates a range of wire gauges and simplifies cable harness assembly in industrial, military, and aerospace applications
Applications
The S2M-135-01-L-D is used in custom cable harnesses for industrial machinery, defense electronics, and aerospace systems where a robust 70-position discrete wire socket must maintain reliable electrical contact under vibration and thermal cycling. Its 2.00 mm pitch and Tiger Eye contacts provide high contact force and multiple wipe points, ensuring low and stable contact resistance below 10 mΩ for power and signal conductors up to 3 A each. The dual-row format consolidates 70 wire connections into a compact mated footprint, simplifying harness routing in tight enclosures.

Frequently Asked Questions
What contact current rating and pitch does the S2M-135-01-L-D Tiger Eye socket support for wire harness assemblies?
The S2M-135-01-L-D features a 2.00 mm pitch and is rated at 3 A per contact, providing a total capacity of up to 210 A across all 70 positions when fully loaded. The Tiger Eye contact geometry delivers multiple independent wipe points per pin, maintaining contact resistance below 10 mΩ even after repeated mating cycles in demanding industrial and aerospace cable harness applications.
How does the Tiger Eye contact design in S2M-135-01-L-D improve reliability compared to standard stamped socket contacts?
Tiger Eye contacts use a dual-beam independent spring design that creates at least 2 independent contact wipe points per pin rather than a single beam. Each wipe point independently scrubs the mating pin during insertion, reducing the risk of intermittent connections caused by oxide build-up, particulate contamination, or mechanical tolerances. This is especially important in military and aerospace harnesses rated to withstand vibration levels exceeding 20 g and temperature cycles from -55°C to +125°C.
For a 70-position mixed power-and-signal cable harness, how does S2M-135-01-L-D compare to two separate 35-position connectors?
Using a single 70-position S2M-135-01-L-D instead of two 35-position connectors reduces the number of harness mating events from 2 to 1 per cable installation, cutting assembly time and eliminating one mechanical interface that could loosen over time. The unified 2.00 mm pitch dual-row housing also occupies less panel real estate than two separate connectors with their individual mounting hardware, which is advantageous in cabinet-mounted industrial control systems where DIN rail space is limited to within 50 mm of adjacent components.
