Industrial proximity sensing

The Sick VTE18-3E4640 is a cylindrical photoelectric proximity sensor designed for automated detection tasks. It operates on a 10 V DC to 30 V DC supply with a maximum power consumption of 30 mA. The NPN switching output uses light-switching mode and connects via a 4-pin M12 male connector. This unit suits production lines and packaging equipment requiring reliable object detection.

IP67 enclosure rating

The plastic housing with PMMA optics achieves an IP67 enclosure rating for dust and water resistance. Ambient operating and storage temperatures span –25 °C to +70 °C. Power consumption remains at or below 30 mA with a supply ripple of 10 %. The infrared LED emits a 2.8° dispersion angle for focused sensing in normal use.

Sustained detection performance

The sensor delivers a maximum sensing range of 5 mm to 400 mm and a defined sensing range of 5 mm to 350 mm. Response time is 2 ms, allowing consistent detection during continuous operation. Sensitivity is adjusted via a potentiometer. UL file NMFT2.E175606 confirms compliance for industrial control equipment.

Questions about this item

How do I connect the M12 4-pin connector and what is the supply voltage range?

Wire the M12 4-pin male connector to a 10 V DC to 30 V DC supply with ripple below 10 %, observing NPN light-switching polarity; the sensor draws up to 30 mA.

What maintenance does the VTE18-3E4640 need and which parts can wear out?

Clean the PMMA optics periodically; the potentiometer adjustment and LED light source are the only items that may require attention over time.

What limits detection distance during continuous operation at high temperature?

The sensing range is 5 mm to 350 mm; at +70 °C ambient the 2 ms response time and LED output stability become the practical limits.
