Feature: Push-Pull coupling enables rapid mating, reducing installation time and misalignment risk. Business Impact: Faster panel wiring, fewer callbacks in the field. Application: Ideal for control cabinets and equipment where speed and reliability matter. Feature: 4-position layout with straight plug and compact footprint (21.1 mm depth, 25 mm width). Business Impact: Smaller footprint in dense assemblies; easier routing in tightly packed panels. Application: Used where space is at a premium in automation lines. Feature: Crimp contact terminations with reliable electrical performance. Business Impact: Easier field terminations, lower rejection rates, and consistent signal integrity. Application: Connectors for pin and coax header configurations in boardmount applications. Feature: IP30 enclosure and plastic shell. Business Impact: Suitable for indoor factory environments with moderate exposure, reducing overall enclosure costs. Application: Panel wiring in machine controls and automation cabinets. Feature: RoHS, REACH, and UL94 V0 compliance. Business Impact: Regulatory-ready, safer product profiles that simplify procurement and CE readiness. Application: Industrial equipment requiring safety certifications and traceability. Feature: No backshell option. Business Impact: Simplified procurement and reduced accessory inventory for compact installations. Application: Quick retrofits or tight-space installations where backshells are impractical.

FAQs
SMS4P3 uses crimp contacts and a straight plug with push-pull coupling for fast mating. Ensure panel cutouts match the 25 mm width and 21.1 mm depth, secure the contact crimps per established IPC standards, and verify IP30 sealing is intact after assembly.
The assembly supports 4 contacts in a 4-position layout, operates from -55 to 125 °C, and achieves IP30 protection. It is RoHS and REACH compliant and UL94 V0 flame rated, providing safe operation in typical automation environments.
SMS4P3 offers a robust temperature range and RoHS/REACH compliance, but it carries IP30 protection. For harsher exposures, select higher IP SMS variants or add protective accessories where possible.
It meets RoHS, REACH, and UL94 V0 flammability standards, includes CE considerations, and supports general industrial compliance for European and global deployments.
SMS4P3 is a socket cable plug for pin and coax boardmount headers in a 4-position layout with a straight plug; compatible with matching SMS series components and crimp contact terminations.
