Push-Pull quick mating reduces mating and unmating time, directly boosting installation efficiency and worker productivity. In factory automation, this translates to shorter changeovers and less idle time when reconfiguring lines, supporting faster time-to-value for new setups. IP40 protection with UL94 V0 flame rating and RoHS/REACH compliance ensures regulatory readiness and safety across rugged environments, minimizing risk during inspections and audits. The four-position insert with crimp contacts enables a compact 4-circuit harness, reducing harness complexity and inventory while preserving signal integrity in control cabinets and robotic cells. With a compact footprint (32.9 mm length, 23.7 mm width, 8.4 mm height), it fits tight enclosures common in modern machine design, enhancing scalability for modular automation. Although backshell options are not available, the design benefits from source-compatible SMS series accessories, enabling straightforward field servicing and standardized maintenance across a plant. Operating from -40 °C to 105 °C, the connector remains reliable in temperature-variant environments typical of industrial floors and automation labs.

FAQs
SMS4PD3 is a straight plug with four crimp contacts designed for use with Souriau SMS series receptacles. It supports a four-cavity layout and does not include a backshell accessory. For best results, pair it with compatible SMS series housings and crimp tooling to ensure consistent termination, tamper-proof mating, and repeatable performance across panel installations.
The connector features four crimp contacts in a 4-cavity configuration, a plastic shell, and a push‑pull coupling with IP40 protection. It operates from -40 °C to 105 °C and carries UL94 V0 flame-rating with RoHS and REACH compliance, making it suitable for indoor factory settings and other controlled industrial environments where safety and regulatory adherence are essential.
Yes. The SMS4PD3 delivers IP40 protection, robust flame resistance (UL94 V0), and broad environmental compliance (RoHS/REACH). Its temperature range and plastic shell design are tailored for rugged automation tasks, such as control panels, robotic cells, and sensor/actuator harnesses, where reliable mating and insulation are critical under demanding conditions.
SMS4PD3 meets UL94 V0 fire safety rating, RoHS and REACH environmental standards, and IP40 ingress protection. These certifications support regulatory compliance in many manufacturing sectors, simplify audits, and help ensure safe operation in typical industrial enclosures and wiring harness assemblies.
The quick mating Push-Pull design minimizes mating time and downtime during line changes or servicing, improving throughput and reducing labor costs. The four-contact, compact form factor reduces harness weight and space requirements, while solid environmental compliance minimizes rework and warranty issues. Over multiple changeovers, these factors translate into measurable maintenance efficiency and faster ROI on automation upgrades.
