Right-angle boardmount with female contacts enables a compact footprint, reducing PCB area and enabling tighter control panels. Business impact: frees board real estate and simplifies routing in dense automation installations, supporting PCB-to-panel transitions and easier field service in industrial equipment. Application: suitable for front mount panel receptacle configurations in compact automation controllers and I/O modules. The push-pull coupling provides secure mating and vibration resistance, improving uptime in rugged environments. Business impact: lowers intermittent contact risk and minimizes maintenance cycles. Application: suitable for machinery enclosures with high vibration profiles. The 3-contact, 20.5 mm depth and 30.2 mm width deliver a compact yet robust interface for 3-way power or signal paths. Business impact: enables dense panel designs and scalable expansion in control cabinets. Application: preferred for small-form-factor PLCs and distributed I/O networks. The plastic shell and IP30 rating help manage heat and insulation in tight enclosures. Business impact: reduces enclosure heat issues and improves electrical isolation. Application: ideal for panel-mounted connectors in automated lines. RoHS and REACH compliance with UL94 V0 flammability support global regulatory alignment. Business impact: simplifies supplier qualification and risk management. Application: suitable for global manufacturing environments and regulated industries.

FAQs
SMS3SE5K9 is a front-mount receptacle with PCB 90° contacts designed for 3 cavities. It supports tight-panel layouts and straightforward mating with 3 gold-plated sockets. Its modular footprint aligns with compact automation enclosures, reducing assembly time and improving field serviceability in control panels.
The connector features three contacts with a 20.5 mm depth and 30.2 mm width, a height of 6.8 mm, and a weight around 4.5 g. It uses gold-plated female contacts, a plastic shell, IP30 protection, and a push-pull coupling mechanism suitable for PCB-to-panel applications in automation systems.
Yes. It is RoHS and REACH compliant, UL94 V0 flame-rated, and rated IP30 for protection against solid objects. Its 125 °C max operating temperature and -55 °C min enable use in diverse industrial locations, while the push-pull coupling provides reliable mating under vibration typical in machinery enclosures.
The SMS3SE5K9 carries RoHS and REACH compliance with UL94 V0 flammability. These certifications support global sourcing and regulatory adherence in industrial equipment, helping procurement meet compliance requirements without component-level redesigns.
The quick mating design reduces assembly time and lock-in maintenance, lowering field failures in vibration-prone environments. Gold-plated contacts deliver lower contact resistance over time, improving signal integrity and reducing troubleshooting costs in dense automation panels.
