FAQs
SMS4R3 is a front mount panel receptacle with a compact 25 mm length and 21.2 mm width designed for standard panel cutouts. Ensure the mating surface is clean, flat, and within the panel tolerance to maintain a consistent seal and alignment. Use proper crimp tooling for four contacts and verify crimp integrity for each conductor to prevent intermittent connections in dynamic industrial environments.
SMS4R3 features four crimp contacts, a push-pull coupling, and an IP40 rating with a temperature range of -40 °C to 105 °C. The plastic shell provides UL94 V0 flame resistance, RoHS and REACH compliance. These specs translate to reliable operation in controlled industrial environments and safer material usage across the product lifecycle.
Ideal for manufacturing automation, automotive machinery, and industrial control panels, the SMS4R3 supports 4-position connectivity in compact spaces. Its front-mount receptacle design and 4-crimp configuration streamline harnessing for cabinets, machine frames, and equipment enclosures, improving installation speed and field serviceability without compromising signal integrity.
SMS4R3 carries UL94 V0 flame rating and complies with RoHS and REACH directives. These certifications help ensure material safety and environmental compliance, simplifying procurement for regulated industries and reducing audit risk when assembling certified control panels and machinery.
The push-pull mating and four-crimp contacts enable rapid mating and demating, decreasing maintenance turnaround and downtime during field servicing. Its compact footprint preserves enclosure space, while the robust IP40 and high-temperature range reduce failure risk. Over a typical lifecycle, this translates to lower maintenance costs, faster production changes, and a stronger overall ROI for automation projects.
