    Waterproof Connector

To meet the growing demand for small waterproof connectors for on-board railway equipment, SOURIAU has developed the SMS IP connector. The latter combines compactness and safety: IP 67 sealing, operating voltage up to 500 V and compliance with the most demanding fire and smoke standards such as R23 / HL23 rating under CEN/TS45-545 and an I3F2 rating in accordance with NF F 16-101/16-102. It is intended for on-board applications such as lighting, door controls, detectors, air conditioning programs, the SMS cabs etc. The connector, intended for the growing need for small on-board connectors on trains, has the advantage of being designed to meet railway standards. Whilst other solutions this size on the market are limited to 230 V, this connector allows voltages of up to 500 V to be used, thanks to generous air gaps and creepage distances. Despite its very compact design, the contacts are protected, allowing connectors to be handled in complete safety. The design rules applied are in accordance with the NF F 61-030 standard. The connector can be used in trains running in severe climatic conditions and is tested under temperatures ranging from -50 to +100 °C. It can withstand shock and vibration in accordance with the EN 61-373 class 2 standard. In its IP 67 version, the connector has pre-fitted grommets to ensure wire-to-wire sealing. It is also available in an IP40 version, without grommets. The stainless steel coupling system is robust and secure, and allows connectors to be fitted side by side without any difficulty. Creepage clearance distances are also respected even when they are packaged tightly together. SMS IP can be used in four ways: extending cable runs, connecting to enclosures, through bulkheads or bracket mounted. It requires the same standard 1.6 mm contacts and associated crimp tooling as the company’s other product families: VGE1, SMS, 838, UTS UT0. This simplifies the process of training and procurement and encourages supply chain optimization.
