Sick VTE18-4P8940 Photoelectric Proximity Sensor PNP

SKU CH-WXS1-CKWCT

Cylindrical photoelectric proximity sensor detects objects from 10 mm to 700 mm using infrared LED, PNP output, and M12 connector

  • Photoelectric detection up to 800 mm range
  • PNP light/dark switching selectable via control cable
  • 250 Hz switching frequency for fast response
  • IP67 enclosure rating withstands harsh environments
  • Operates from –25 °C to +70 °C

Sensing Range and Output Type

The Sick VTE18-4P8940 is a photoelectric proximity sensor with an energetic detection principle. It offers a sensing range from 10 mm to 700 mm with a maximum reach of 800 mm. The device provides a PNP switching output with selectable light or dark switching modes via an L/D control cable. This sensor suits automation tasks requiring reliable object detection within this distance.

Supply Voltage and Switching Frequency

Operation requires a 10 V DC to 30 V DC supply with a maximum 10 % ripple. Power consumption sits at 30 mA while the output handles up to 100 mA. The switching frequency reaches 250 Hz with a 2 ms response time. These electrical limits define the sensor's compatibility with control systems and its ability to detect fast-moving targets in industrial environments.

Housing Build and Connection

The cylindrical M18 x 1 housing measures 75 mm in length and uses PBT/PC plastic with a PMMA optic. An IP67 enclosure rating protects against dust and temporary immersion. A radial optical axis emits an infrared LED spot of 40 mm diameter at 800 mm. Connection is via a 4-pin M12 male connector, while a 270° potentiometer allows sensing range adjustment. The unit weighs 100 g and operates from –25 °C to +70 °C.

Questions about this item

Which sensing-range version of the VTE18-4P8940 should I choose for a 700 mm detection task?

The sensor offers a maximum sensing range of 10 mm to 800 mm and a specified sensing range of 10 mm to 700 mm, so the 700 mm figure is the reliable operating distance for consistent detection.

What does the 250 Hz switching frequency mean when the sensor is installed on a production line?

A 250 Hz switching frequency allows the sensor to detect up to 250 objects per second, with a 2 ms response time, suitable for fast automated processes.

How does the M12 4-pin connector and 10–30 V DC supply affect wiring in a standard industrial cabinet?

The sensor connects via a 4-pin M12 male connector and operates on 10 V DC to 30 V DC with PNP output, compatible with typical PLC input modules and standard industrial power supplies.
