FAQs
SMS3R3 is a front mount panel receptacle designed for compact control panels. It uses a panel-mount approach with a 25 mm depth, 16.2 mm width, and 15.2 mm height, making it compatible with common DIN-rail backed enclosures and standard cutouts. The design supports crimp contacts and a push-pull mating scheme, while noting that no backshell accessory is provided. Users should confirm panel cutout tolerances and ensure crimp tooling aligns with the 3-position, 3-cavity layout for reliable installation.
SMS3R3 features three crimp contacts in a 3-cavity configuration with a 25 mm depth and IP40 protection. The operating temperature range spans from -40 °C to 105 °C, and the shell is plastic. Safety and compliance are reinforced by UL94 V0 flame rating and RoHS/REACH adherence. Its front-mount panel receptacle design is optimized for robust, vibration-tolerant connections in automation equipment.
Best suited for factory automation, control panels, and machine housings where a compact, quick-mating connector is advantageous. With a 3-position layout and push-pull coupling, it supports efficient maintenance in environments requiring reliable crimp terminations and smoke/fire safety. Its IP40 rating and RoHS/REACH compliance make it a dependable choice for general industrial, packaging, and material handling applications.
SMS3R3 meets UL94 V0 flame resistance, IP40 enclosure protection, and RoHS/REACH compliance, aligning with common industrial and automotive sourcing requirements. This reduces regulatory risk during procurement and supports safer, more compliant installations in machinery, control panels, and equipment enclosures. If additional certifications are required (e.g., SIL or CE in specific programs), verify project scope and supplier documentation for traceability.
By enabling quick mating with a push-pull mechanism and reliable crimp terminations, SMS3R3 reduces assembly time and field service visits, lowering labor costs and downtime. Its compact footprint simplifies inventory management and panel design, contributing to faster deployment and easier upgrades. The robust environmental specs also minimize replacement cycles in demanding industrial environments.
