Eaton SMS4RE4TR29 Quick Mating Plastic Connector - IP30
Part Number: SMS4RE4TR29
Quick Summary
The Eaton SMS4RE4TR29 Quick Mating Plastic Connector is a compact front-mount receptacle designed for PCB-based control panels. Engineers often struggle with difficult mating cycles and unreliable connections in tight spaces, and this SMS series solution provides a robust, quick mating interface to simplify enclosure design and minimize downtime. With Push-Pull coupling, tin pre-plated PCB contacts, and a rugged plastic shell, it delivers dependable performance across -55 to 125 °C and IP30 protection. The 4-contact, 4-cavity layout fits four signals or small power paths in a slim 13.4 mm depth and 5.9 mm width footprint, reducing panel cutouts. This supports cost-effective assemblies and rapid field servicing, boosting overall uptime and operational efficiency.

FAQs
The SMS4RE4TR29 is designed as a front-mount receptacle with no backshell accessory. To install, prepare the panel cutout, align the receptacle with the opening, and secure using standard panel mounting practices for rectangular connector housings. Ensure the PCB contact side mates cleanly with the corresponding plug, then engage the Push-Pull coupling to secure the connection. This streamlines installation and reduces the need for additional hardware.
Key specs include 4 contacts with tin pre plated plating, a 4-cavity layout, Push-Pull coupling, IP30 protection, and an operating range of -55 °C to 125 °C. The receptacle is plastic-shelled, front-mount panel rated, and suitable for PCB edge connections within compact assemblies. Verify durability under intended vibration, thermal cycling, and potential exposure to REACH and UL94 V0 compliance requirements in your environment.
Yes. The SMS4RE4TR29 is ideal for compact automation panels and sensor interfaces where space is at a premium but reliable signal integrity is required. Its 4-channel layout supports multiple signals on a single connector, and front-mount panel mounting simplifies integration in densely packed control cabinets and machine housings.
The connector features IP30 protection and UL94 V0 flammability rating, with REACH compatibility as part of the environmental considerations. Tin pre-plated contacts contribute to corrosion resistance. These attributes help meet common industrial and safety standards in many regions.
By enabling quick mating with Push-Pull coupling, front-mount installation, and four-channel capability, the SMS4RE4TR29 reduces installation time and maintenance downtime. Its lightweight plastic construction and robust temperature range contribute to longer service life and fewer replacements, delivering tangible lifecycle value for automation projects.
