Eaton SM20M1S18 Crimp Contact - RoHS REACH Compliant
Part Number: SM20M1S18
Quick Summary
The Eaton SM20M1S18 Crimp Contact is a male stamped connector used in industrial automation harnesses. Selecting mismatched contacts can cause intermittent signals, corrosion, and costly field service, especially in throughput-driven assembly lines. This part carries RoHS and REACH compliance to meet modern regulatory requirements and supplier sustainability programs. With a compact 28 mm length, 3.5 mm width, and 2.7 mm height, it fits tight junctions while supporting 22–20 AWG wire. Gold on the active contact and tin on the rear reduce wear and ensure long-term reliability across demanding industrial settings.

FAQs
SM20M1S18 is designed for use with Eaton Souriau SC/SM series. It comes on a reel to support automated feeding and requires compatible crimp tooling for 22-20 AWG wires. Ensure proper crimp depth and alignment to maintain the stamped and formed geometry, which minimizes mis-crimps and rework on high-volume harness builds.
Key specs include a 28 mm length, 2.7 mm height, 3.5 mm width, and 2.7 mm diameter with a 0.4 g weight. The contact size is 16 AWG, with wire range 22-20 AWG. Plating is gold on the active part and tin on the rear, and the packaging is reeled for efficient automation.
Yes. The SM20M1S18 stamped and formed contact complies with RoHS and REACH regulations, supporting regulatory procurement, sustainability programs, and reduced risk of restricted substances in controlled environments.
This contact is well-suited for industrial automation harnesses, control panels, instrumentation, and sensor interfaces that use Souriau SC/SM series connectors. Its compact form, reliable plating, and reel packaging make it ideal for high-volume assembly lines and dense panel designs.
Benefits include extended service life from gold on active surfaces and tin on the rear, reducing wear and resistance drift. Reel packaging supports faster line feeding and lower handling time, while RoHS/REACH compliance minimizes regulatory delays, delivering lower maintenance costs and improved system uptime over the product lifecycle.
