M8 & M12 SMT Connectors Amphenol LTW M8 and M12 Surface-Mount Technology (SMT) Connectors are two-piece connectors designed for printed circuit boards (PCB). These connectors can be equipped on both sides and do not have any via holes for the connection pins, helping to reduce the PCB surface area. These Amphenol LTW connectors feature an IP68 (mated) / IP65 (unmated) rating and a UL 94V-0 flammability rating. These connectors use a shield spring for further shielding function and achieve IEC 61076-2-101 and -104 compliance for the M12 and M8 series, respectively. Amphenol LTW SMT connectors are ideal for industrial automation, mass rail transit / railway, communication systems, marine, LED, and lighting applications.
