It mounts directly to the front of the actuator, so the panel cutout and mounting hole pattern are driven by the actuator, not the adapter — no extra DIN-rail space needed. The adapter provides two digital inputs for the E-stop contacts and communicates over the AS-Interface bus, making it a drop-in component for a SIRIUS 3SB3 emergency-stop station. The adapter is safety-related (Safety-Related = 2). It provides two digital inputs for E-stop contacts and no outputs. ## Compliance documentation RoHS compliance date is noted as 05/28/2009, indicating the part meets the EU RoHS directive since that date. No UL or CSA listing is recorded in the evidence; the primary approvals are CE and the AS-Interface certification implied by the product designation. The reference code according to IEC 81346-2 is S, which classifies it as a switching/signaling device in a standardized panel labeling scheme.","metaTitle":"Siemens 3SF5402-1AA04 AS-Interface F-adapter, 2 inputs, IP20","metaDescription":"Siemens 3SF5402-1AA04 AS-Interface F-adapter for emergency-stop mushroom actuator, 2 digital inputs, spring-loaded terminals, IP20, -25 to +70°C.
