Feature → Business Impact → Application: The push-pull coupling enables rapid mating and repeatable insertions, reducing assembly time and misalignment risk on dense control panels used in robotics and machinery. This translates to lower labor costs and fewer field failures when wiring complex automation systems featuring 9-position connectors. Feature → Business Impact → Application: Gold-plated PCB contacts provide reliable, corrosion-resistant signal paths, improving long-term performance in harsh industrial environments. This is especially beneficial for critical control loops and high-reliability sensing networks in packaging lines and material handling. Feature → Business Impact → Application: IP30 protection protects internal contacts from dust ingress in cabinet-mounted installations, supporting compliant operation in non-hazardous environments and extending service intervals in enclosed control panels. Feature → Business Impact → Application: Operating temperature range of -55 °C to 125 °C ensures functionality across climate zones and manufacturing floors, minimizing downtime due to environmental factors in automotive, food & beverage, and process industries. Feature → Business Impact → Application: Compact 13.4 mm depth and 16 mm width with a 9-contact layout deliver a space- and weight-efficient solution for space-constrained I/O boards, enabling denser PCB designs and faster time-to-market in industrial equipment and OEM panels.

FAQs
To install the SMS9SE3K9 on a front-mount panel, align the receptacle with the panel cutout, insert the connector until firmly seated, and engage the push-pull coupling to complete the mating cycle. Ensure the panel surface is clean and the connector is oriented to avoid contact bending. Verify contact integrity with a simple continuity check after installation.
The SMS9SE3K9 is a 9-position PCB receptacle with gold-plated contacts, offering low contact resistance and high corrosion resistance. Its push-pull coupling ensures fast, repeatable mating, while the IP30 housing provides environmental protection. Combined with a compact 13.4 mm depth, it supports dense PCB layouts typical of automated control panels.
Yes. The SMS9SE3K9 complies with RoHS and REACH environmental standards and features a UL94 V0 flammability rating. This combination helps manufacturers meet regulatory requirements for electrical and electronic equipment used in industrial settings, while maintaining high safety standards for internal wiring and panel assemblies.
When integrating with other SMS series parts, verify cavity count, contact type, and mating interfaces to ensure full electrical compatibility. The SMS9SE3K9 is a 9-contact PCB receptacle with front-mount panel mounting and a push-pull coupling, so pairing with corresponding male housings and backshells (where available) should maintain IP rating and mechanical fit without forcing mismatched layouts.
The SMS9SE3K9 reduces maintenance and downtime through reliable gold-plated PCB contacts and a robust push-pull mating mechanism, which speeds assemblies and reduces mis-mating risks. Its compact footprint frees panel space, enabling denser wiring layouts and faster changeovers in high-mix manufacturing environments, delivering lower total cost of ownership over the product lifecycle.
