The Siemens 3SF1114-1QV10-1BA1 is a SIRIUS mechanical safety switch in a narrow metal block housing with screw fixing. It carries two normally-closed safety contacts with positive opening action, rated for 30 V insulation voltage and 0.8 kV surge withstand. The 24 V LED indicator gives a quick visual on the AS-Interface loop status — useful when you're fault-isolating a guarded zone without breaking the seal. IP66/IP67 means the metal enclosure with cathodic dip coating handles washdown and outdoor exposure — food-and-bev or conveyor lines where hose-down cleaning is routine. The 0.1 mm repeat accuracy matters for consistent guard-door detection in cycle-dependent processes.
Substance prohibitance compliance (RoHS/REACH) is documented per the 03/01/2017 date code. The AS-Interface slave profile is 0.B.F, and the M12 pinout is fixed: Pin 1 = ASI+, Pin 3 = ASI-.
Integration
Mounts in any orientation via screw fixing; the 40 mm width and 124 mm length fit standard machine-frame brackets. The M12 plug (4-pole) connects directly to an AS-Interface network — no separate power supply needed for the switch itself, as the 24 V LED and AS-i electronics draw from the bus. Slow-action contacts with positive opening meet IEC 60947-5-1 requirements for safety circuits. Compatible optional actuators include the standard 3SE5000-0AV01, vertical-fixing 3SE5000-0AV02, transverse-fixing 3SE5000-0AV03, radius left/right (3SE5000-0AV04/0AV06), and universal 3SE5000-0AV05. The ID1 code is set to F (hex, variable 0...F) — addressable per the AS-Interface master configuration.
