SICK VTE18-4N8940 photoelectric sensor
The SICK VTE18-4N8940 is a cylindrical photoelectric proximity sensor that uses an infrared LED to detect objects. It provides an NPN switching output with selectable light or dark switching via an L/D control cable. The housing is rated IP67 and operates from –25 °C to +70 °C.
Suited for short-range presence detection
This sensor suits applications that need reliable detection between 10 mm and 700 mm with a 2.8° angle of dispersion. A potentiometer allows sensitivity adjustment. Buyers who need longer sensing distances, analogue output, or a different output type should look at alternative models.
Integrates into 10–30 V DC control systems
The unit connects through a 4-pin M12 male connector and draws up to 30 mA from a 10 V DC to 30 V DC supply. Its plastic housing and PMMA optics keep weight low while maintaining the IP67 enclosure rating. A response time of 2 ms supports fast switching in automated sequences.

Questions about this item
What supply voltage must my system provide for the VTE18-4N8940 to operate?
The sensor requires a DC supply between 10 V and 30 V with no more than 10 % ripple.
Will the M12 4-pin connector on this sensor mate with the M12 cables I already use on older Sick sensors?
Yes, the VTE18-4N8940 uses a standard M12 4-pin male connector compatible with existing M12 cable assemblies.
How can I verify the sensor is detecting correctly after I mount it and apply power?
Turn the potentiometer until the output toggles at the desired distance up to 700 mm, then confirm the NPN signal changes state within 2 ms.
