It mounts directly to an AS-i enclosure and handles 4 to 6 control points through an M25 cable gland. Rated IP67, the housing and the M12 connector survive washdown environments — suitable for food-and-bev or packaging lines where the enclosure sees hose spray. Fastening method is direct mounting — no DIN rail adapter needed. The M25 gland accepts cable diameters typical for AS-i trunk lines, and the M12 socket provides a standard fieldbus drop.","metaTitle":"Siemens 3SF5900-2CF AS-i Connection Element, IP67, M12","metaDescription":"Siemens 3SF5900-2CF AS-i connection element for M12 connectors, IP67, -25 to +70°C.
