Overview
The FQ-SDU20 is an Omron FQ2 series sensor controller with a single NPN output, powered at 26.4 V and rated for 0°C to 50°C ambient. It mounts on a DIN rail and is in active production.
Selection considerations
Compared to the ZS-HLDC11, the FQ-SDU20 shares the same 26.4 V supply and DIN rail mount but lacks an integrated display. Choose the ZS-HLDC11 when on-unit readout is needed; the FQ-SDU20 fits where display is handled externally or not required.
