Helpful for Model Matching:
| Sensor identity | Four-wire slot photoelectric sensor with infrared 940 nmLED source, not a magnetic reed or cylinder-groove switch. T/F/R/K/L/Y are six physical housing/mounting profiles, not different sensing principles. |
| Slot and target | 5.5 mm specification is the slot width, not external sensing reach. Minimum opaque target 0.8×1.2 mm. Confirm target passage, thickness and alignment to the optical axis; not a universal transparent-target guarantee. |
| Supply and consumption | Supply 5–24VDC±10%; consumption≤10 mA. Brown positive supply, blue 0V. Match actual PLC/controller voltage and output load separately. |
| Output current by type | N four-wireNPN output DC5–24V≤100 mA; P four-wirePNP≤50 mA. These output limits are not the 10 mA consumption. No universal 100/200 mA output for both types. |
| Two output wires | BlackLight-on andwhiteDark-on are separate outputs. NPN loads connect toward positive supply; PNP loads toward 0V per diagrams. Both usebrown+/blue 0V. Do not collapse these into a selectable two-wireNO/NC contact or promise unused-wire wiring without confirmation. |
| Cable lengths | 020=2 m;030=3 m;050=5 m cable. No connector, axial orientation, other cable length or cable-free ordering field is published. |
| Response and repeatability | Published repeatability≤0.01 mm without a complete application test protocol in this sheet. ResponseLight-on≤20 μs, Dark-on≤80 μs. Frequency≥3 kHz is the illustrated rotating-disc test value, not every installed machine cycle. |
| Environment | Operating−10 to+70°C,5–85%RH; storage−30 to+80°C,5–95%RH. PublishedIP65. Receiver ambient incandescent illumination≤1000 lux; avoid direct light into receiver. Confirm actual moisture/dust/ambient-light conditions. |
| Mounting and wiring precautions | All profiles useM3 mounting screws; hole orientation, slot depth and optical axis differ by profile. Wait 50 ms after power-on before use. Keep signal cable away from power lines and check inductive-load surge protection. No automatic compatibility with magnetic-switch brackets or sensor grooves. |
| RFQ inputs | Send full sensor code or label, profile, NPN/PNP, cable length, actual supply/output load, controller wiring, target geometry, mounting photo, quantity and destination. Confirm installation and availability through inquiry. |

No. PRSU senses an opaque target through a 5.5 mm optical slot. It has four wires, with separate blackLight-on andwhiteDark-on outputs. Match profile, target and NPN/PNP controller wiring; do not assume magnetic-groove or bracket interchangeability.
