It provides two digital inputs for the safety circuit and communicates over the AS-i bus, eliminating the need for a separate safety relay in many panel layouts. Rated for -25 to +70 °C ambient operation, the adapter mounts directly to the front of the panel — the fastening method is front mounting, so it sits on the enclosure door or sub-panel rather than on a DIN rail. The AS-i FK terminal connection type uses the standard AS-Interface flat cable piercing technique, which simplifies wiring: the adapter clamps onto the AS-i profile cable without stripping or screw terminals. Dimensions are 52 mm deep, 30 mm wide, and 61 mm high — a compact footprint that fits into tight door cutouts. The part is RoHS-compliant with a substance prohibition date of 05/28/2009, indicating it meets the EU RoHS directive. The reference code according to IEC 81346-2 is S, which classifies it as a control/signaling device in system documentation.","metaTitle":"Siemens 3SF5402-1AA01 AS-Interface F-adapter, 2 DI, IP20, fr","metaDescription":"Siemens 3SF5402-1AA01 AS-Interface F-adapter for EMERGENCY-OFF control device SIRIUS 3SB3. 2 digital inputs, IP20, front mounting, -25...+70 °C.
