Cylindrical plastic photoelectric proximity sensor with M12 connector

Sick

Sick VTE18-4N8640 Photoelectric Proximity Sensor NPN

SKU CH-E3DA-4PSZF

Photoelectric proximity sensor with 10–700 mm range, NPN output and IP67 housing

  • Photoelectric sensing up to 800 mm range
  • NPN output with selectable light/dark switching mode
  • Infrared LED source with 2.8° dispersion angle
  • IP67 enclosure withstands harsh industrial environments
  • Operates reliably from –25 °C to +70 °C

Sick VTE18-4N8640 Sensor Purpose

The Sick VTE18-4N8640 is a photoelectric proximity sensor with an NPN switching output. It detects objects using infrared light emitted from an LED source within a cylindrical plastic housing. The unit operates on a 10 V DC to 30 V DC supply voltage with a power consumption of 30 mA. It is designed for industrial automation tasks requiring reliable object detection.

Suits Fixed Range Detection Not Precision

This sensor suits applications needing adjustable sensing ranges between 10 mm and 700 mm with a maximum reach of 800 mm. The 2.8° angle of dispersion provides a focused detection beam. It is not for buyers who require analogue distance measurement or colour differentiation. Users needing a PNP output configuration or a different connection interface should look at alternative models.

Simple M12 Connection With Potentiometer Adjustment

Installation uses a male M12 4-pin connector for straightforward wiring into existing control systems. Sensing distance is set via an external potentiometer while light or dark switching is selected using the L/D control cable. The IP67 enclosure rating protects against dust and water ingress during mounting. Ensure the supply voltage stays within the 10 V DC to 30 V DC range to avoid damage.

Questions about this item

What voltage supply must I already have for this sensor to operate?

You need a 10 V DC to 30 V DC power source with ripple below 10 % and at least 30 mA available for the sensor.

Will the M12 4-pin connector fit the cables I already use for older Sick sensors?

Yes, the sensor uses a standard male M12 4-pin connector compatible with existing M12 4-pin cables.

How can I verify the NPN output is switching correctly after wiring?

Apply an object within the 10 mm to 700 mm sensing range and confirm the load toggles with a response time of 2 ms.
