Sick WTV4-3N1341 Photoelectric Sensor NPN 15-50mm 10-30V DC 2m Cable

SKU CH-R3DC-SVT16

Miniature photoelectric proximity sensor with background suppression detects objects at 15-50 mm using visible red PinPoint LED and NPN output

  • Miniature 16 mm x 39.5 mm housing fits tight spaces
  • Background suppression ignores shiny or film-wrapped surfaces
  • PinPoint LED gives sharp 10 mm spot at 40 mm
  • NPN output switches in under 0.5 ms at 1000 Hz
  • IP67 and IP66 ratings withstand wash-down and dust

Miniature Photoelectric Sensor

The Sick WTV4-3N1341 is a rectangular background-suppression sensor that detects objects from 15 mm to 50 mm using a visible red PinPoint LED. Its 16 mm by 39.5 mm by 12 mm ABS housing fits tight machine spaces and carries IP67 and IP66 enclosure ratings. The NPN light-switching output suits PLC inputs in packaging, assembly and material-handling lines.

Thermals noise and power draw

The unit draws 20 mA from a 10 V DC to 30 V DC supply with ripple below 5 Vpp and operates from –40 °C to +60 °C without a fan. Solid-state switching produces no acoustic noise and the response time stays under 0.5 ms at 1,000 Hz switching frequency. Circuit protection covers reverse polarity, short-circuit and transient over-voltage conditions.

Bundled cable and adjustment

A 2 m PVC cable with 0.14 mm² conductors and 3.4 mm outer diameter is permanently attached, eliminating separate connector purchases. The five-turn potentiometer provides repeatable background-suppression tuning for uneven or film-wrapped targets. V-optics shape the 10 mm light spot at 40 mm distance to improve detection reliability on shiny surfaces.

Questions about this item

How do I install the WTV4-3N1341 sensor and which wiring step is often missed?

Mount the 16 mm x 39.5 mm x 12 mm ABS housing, connect the brown wire to 10-30 V DC, blue to 0 V, and black to the load for NPN light-switching output; the step often missed is confirming the load does not exceed 100 mA.

What maintenance will the WTV4-3N1341 need over time?

Periodically clean the PMMA optics to maintain the 650 nm PinPoint LED spot; the 2 m PVC cable and IP67/IP66 enclosure require no scheduled replacement unless physically damaged.

What limit appears first during continuous operation of the WTV4-3N1341?

The 100 mA maximum output current is the first hard limit; exceeding it triggers the built-in short-circuit protection and stops switching.
