Selection vs peers
Compared to the FL-STC15, the FQ-SDU25 runs on a 26.4 V supply rather than 24.0 V, and its controller type is Sensor, not Lighting. The FQ-SDU25 also mounts solely on DIN Rail, while the FL-STC15 accepts both Chassis Mount and DIN Rail. The FQ-SDU25 outputs PNP, whereas the ZS-LDC11 outputs NPN — a key difference for wiring compatibility with existing PLC input cards.
The FQ-SDU25 is listed as active in Omron's current catalog. Sourcing is through standard distribution channels; an RFQ confirms lead time and availability for the exact build code.
