Sick

Sick VTE18-3P4640 photoelectric proximity sensor PNP

SKU CH-ABBB-Q2HZ1

M18 cylindrical photoelectric proximity sensor detects objects up to 350 mm with PNP output and IP67 protection

  • Energetic photoelectric detection up to 400 mm range
  • PNP light-switching output with 100 mA current capacity
  • 250 Hz switching frequency for rapid response cycles
  • IP67 rated plastic housing withstands –25 °C to +70 °C
  • M12 4-pin connector on 10–30 V DC supply

Cylindrical M18 photoelectric sensor

The Sick VTE18-3P4640 is an energetic photoelectric proximity sensor in a cylindrical M18 × 1 housing that measures 78 mm in length. It emits infrared light from an axial LED and detects objects from 5 mm to 350 mm with a maximum range of 400 mm. The unit weighs 100 g and uses a PBT/PC body with PMMA optics. A four-pin M12 male connector provides the electrical interface.

Suits DC control panels needing simple presence

Engineers wiring 10 V to 30 V DC systems who need a PNP light-switching output at 250 Hz will find the sensor a direct fit. The IP67 enclosure and –25 °C to +70 °C temperature span cover most indoor and sheltered outdoor installations. Buyers who require background suppression, teach-in adjustment or a complementary NPN output should look at other models.

350 mm sensing range with 400 mm maximum

At 350 mm the sensor reliably switches on diffuse targets, while the 400 mm ceiling gives extra margin for larger or more reflective objects. The 2 ms response time and 100 mA output current handle typical PLC inputs and small actuators. Beyond 350 mm detection becomes application-dependent, and the fixed 2.8° beam angle cannot be narrowed for long-range precision.

Questions about this item

Does this M18 sensor need a specific mounting bracket or can I use standard M18 hardware?

The housing uses an M18 x 1 thread diameter and is 78 mm long, so standard M18 mounting nuts and brackets will fit the cylindrical plastic body.

Will the 250 Hz switching frequency work with my existing 10–30 V DC control system?

Yes, the sensor operates on 10 V DC to 30 V DC with a PNP light-switching output rated at 100 mA, matching typical 24 V DC PLC inputs and the 250 Hz switching speed.

How can I confirm the sensor is detecting correctly after wiring the M12 connector?

When an object enters the 5 mm to 350 mm sensing range, the PNP output switches high; you can verify this by measuring the output voltage or watching the PLC input LED change state.
