Photoelectric Proximity Sensor NPN
The Sick VTE18-3N8412 is a cylindrical photoelectric proximity sensor with an NPN switching output. It operates on a 10 V DC to 30 V DC supply voltage and uses an infrared LED light source. The housing is made of nickel-plated brass and plastic with an IP67 enclosure rating for harsh environments.
Suited for dark-switching detection up to 700 mm
This sensor suits automation tasks requiring dark-switching detection within a 10 mm to 700 mm sensing range. A 2.8° angle of dispersion provides a focused beam. Builders needing a PNP output, a longer range beyond 800 mm, or a different connection type than the fixed 2 m PVC cable should look elsewhere.
Stable response under continuous industrial use
With a 2 ms response time and a power consumption of 30 mA, the unit maintains consistent switching performance during sustained operation. The IP67 rating protects internal electronics from dust and water ingress across an ambient temperature span of –25 °C to +70 °C. A metal housing resists mechanical stress and vibration over long shifts.

Questions about this item
What DC voltage supply must I already have to power the VTE18-3N8412 sensor?
The sensor operates on a 10 V DC to 30 V DC supply with a maximum ripple of 10 %. Ensure your power source stays within this range.
Will the NPN dark-switching output work with my existing PLC input card?
The sensor provides an NPN dark-switching output. It will work with a PLC input that sinks current when the output pulls low, provided the card accepts 10 V to 30 V logic levels.
How can I verify the VTE18-3N8412 is detecting correctly after wiring it?
With power applied, place a target within the 10 mm to 700 mm sensing range. The output should change state when the infrared beam is interrupted; adjust the potentiometer if needed.
