- Operates on 10–30 V DC with 2 ms response time
Industrial detection sensor
The Sick VTE18-3N4940 is a cylindrical photoelectric proximity sensor designed for automated industrial detection tasks. Its NPN dark-switching output and M12 connector suit PLC input modules in packaging, material-handling and assembly equipment.
Sustained operation profile
The sensor draws a maximum of 30 mA from a 10 V DC to 30 V DC supply with 10 % ripple tolerance. An IP67 enclosure and an operating range of –25 °C to +70 °C allow continuous duty in wash-down zones and unheated factories without thermal derating.
Decisive sensing range
The adjustable potentiometer sets a usable detection window from 5 mm to 350 mm using an infrared LED with a 2.8° dispersion angle. Applications requiring longer range or a different output logic will need another device.

Questions about this item
How much power does the VTE18-3N4940 sensor draw during continuous operation?
The sensor consumes a maximum of 30 mA from a 10 V DC to 30 V DC supply with ripple up to 10 %.
Which connector and voltage supply must already be available to install this sensor?
A male M12 4-pin connector and a 10 V DC to 30 V DC power source are required for connection.
Will the IP67-rated housing survive the same temperature range as my existing IP67 equipment?
Yes, the sensor operates from –25 °C to +70 °C, matching the typical industrial IP67 temperature specification.
