FAQs
To install SMS4SE3K9, align the four PCB contacts with the mating receptacle, secure the front-mount panel using appropriate hardware, and engage the Push-Pull coupling to complete the connection. Ensure the installation maintains RoHS/REACH compliance and operates within the -55 °C to 125 °C range. The design’s loaded contact delivery simplifies wiring, reducing setup time and error potential during panel assembly.
SMS4SE3K9 supports four contacts with gold plating, configured as a PCB contact type, in a 4-cavity layout. It uses Push-Pull coupling and provides IP30 protection. The connector measures 13.4 mm in depth, 21.3 mm in height, and 5.9 mm in width, with a weight around 3.1 g and operating temperatures from -55 to 125 °C. This combination ensures robust performance in typical automation environments.
Yes. The SMS4SE3K9 is RoHS and REACH compliant, UL94 V0 rated for flame resistance, and rated IP30 for enclosure protection, making it suitable for many automation sensors and panel interfaces. Its wide operating temperature range and gold-plated PCB contacts provide reliable performance in challenging industrial environments and high-density assemblies.
The SMS4SE3K9 carries RoHS and REACH compliance and UL94 V0 flammability rating, supporting regulatory requirements for industrial equipment. Its IP30 rating provides enclosure protection for non-enclosed or partially protected assemblies. These certifications help meet safety and environmental standards across multiple regions.
Using SMS4SE3K9 reduces assembly time through loaded contact delivery and a compact, front-mount form factor, which saves panel space and speeds maintenance. The four gold-plated PCB contacts deliver reliable signal integrity, while the Push-Pull coupling enables quick mating. Together, these features lower downtime and improve overall equipment reliability in high-mix production lines.
