Applications
The S2M-138-01-L-D is designed for wiring harness assemblies requiring 76 discrete wire connections at 2.00 mm pitch, such as those found in aerospace avionics, defense electronics, and heavy industrial machinery. Its Tiger Eye contact system maintains secure electrical contact over repeated mating cycles under mechanical shock and vibration. This connector is commonly used in panel-wiring applications where field-replaceable, solder-free wire termination is required for serviceability.

Frequently Asked Questions
How does the S2M-138-01-L-D's 76-position count and 2.00 mm pitch affect wiring harness routing?
With 76 positions at a 2.00 mm pitch, the S2M-138-01-L-D accommodates a high channel count in a manageable single-row footprint. The 2.00 mm pitch supports standard 24 AWG to 28 AWG wire gauges, making harness routing practical without special micro-pitch tooling. This balance of density and wire gauge compatibility is especially valuable in aerospace and industrial control panel designs where space and wire gauge are both constrained.
For a defense avionics wiring harness, how does Tiger Eye technology in S2M-138-01-L-D improve reliability over standard single-point contacts?
Tiger Eye contacts provide a four-point contact interface compared to the single-point interface of conventional socket contacts. In a 76-position connector like the S2M-138-01-L-D, this translates to 304 contact points maintaining electrical continuity, dramatically reducing the probability of an open circuit due to fretting corrosion or vibration-induced micro-movement, which is critical in defense avionics rated for MIL-standard shock and vibration profiles.
When is S2M-138-01-L-D preferred over a comparable 76-pin IDC connector for harness builds?
The S2M-138-01-L-D is preferred over IDC alternatives when individual wires must be routed independently rather than in a flat ribbon cable, or when mixed wire gauges and colors are required for harness identification. At 2.00 mm pitch with discrete wire insertion, technicians can replace a single wire without disturbing adjacent circuits, reducing maintenance downtime and rework cost in field-deployed 76-channel systems.
