SICK VTE18-4N8140 Photoelectric proximity sensor NPN

SKU CH-M8HR-CWN8C

Photoelectric proximity sensor detects objects from 10 mm to 700 mm with infrared LED, NPN output and IP67-rated metal housing

  • Detects objects up to 800 mm away
  • Infrared LED with narrow 2.8° dispersion angle
  • Adjustable sensing distance via potentiometer
  • IP67-rated metal housing for harsh environments
  • Operates reliably from –25 °C to +70 °C

Industrial proximity sensor

The Sick VTE18-4N8140 is a cylindrical photoelectric proximity sensor designed for industrial automation tasks that require non-contact object detection. It operates on a 10 V DC to 30 V DC supply and provides an NPN switching output with selectable light or dark switching via a control cable. The metal brass nickel-plated housing meets IP67 enclosure rating for harsh environments.

Sustained operation stability

The sensor maintains consistent detection across its 10 mm to 700 mm sensing range with a 2.8° angle of dispersion and a 2 ms response time. Power consumption stays at 30 mA with supply ripple limited to 10 %, ensuring stable performance during continuous duty cycles. The infrared LED light source and PMMA optics resist degradation across the –25 °C to +70 °C operating temperature range.

800 mm maximum sensing reach

The decisive specification is the 800 mm maximum sensing range, which defines the furthest distance at which the sensor can reliably detect a target under ideal conditions. Applications needing longer reach or a different output type such as PNP will require an alternative sensor model.

Questions about this item

How much heat or power does the VTE18-4N8140 draw when running continuously?

It consumes 30 mA from a 10–30 V DC supply with a 2 ms response time, and operates from –25 °C to +70 °C.

What power supply and connector must I already have to use this sensor?

You need a 10–30 V DC source and a 4-pin M12 male connector to match the sensor’s connection type.

Will the VTE18-4N8140 work alongside older 24 V DC control gear I’m keeping?

Yes, its 10–30 V DC supply range and NPN light/dark switching output are compatible with typical 24 V DC systems.
