Cylindrical angled metal sensor with M12 connector

Sick

Sick VTE18-3N8340 Photoelectric proximity sensor NPN

SKU CH-XQD4-E3FWC

Cylindrical photoelectric proximity sensor with NPN dark-switching output, 10 mm to 700 mm sensing range, IP67-rated metal housing, and M12 connector for 10–30 V DC supply

  • NPN output integrates with sinking-input PLCs
  • Sensing up to 700 mm covers close and mid-range detection
  • Infrared LED with 2.8° beam reduces false triggers
  • IP67 brass housing withstands wash-down and impact
  • 10–30 V DC supply fits standard industrial power rails

Industrial sensing range

The Sick VTE18-3N8340 is a cylindrical photoelectric proximity sensor with an angled light emission designed for industrial automation. Its NPN dark-switching output and M12 4-pin connector suit PLC inputs and machine-control cabinets. The brass nickel-plated metal housing and IP67 enclosure rating allow installation in harsh environments. It operates reliably from –25 °C to +70 °C.

700 mm practical detection

The sensor detects objects from 10 mm up to 700 mm using an infrared LED with a 2.8° dispersion angle. A potentiometer provides manual adjustment of the switching threshold for different target reflectivity. Maximum specified range reaches 800 mm under ideal conditions, but reliable operation should be planned within the 700 mm rating. Response time is 2 ms for high-speed sorting or counting tasks.

10–30 V DC supply limits

The unit requires a 10 V DC to 30 V DC supply with ripple below 10 % and draws no more than 30 mA. Voltage outside this window or excessive ripple will cause erratic switching or damage. The M12 connector pins must match the NPN sinking wiring expected by the controller. UL file NMFT2.E175606 confirms compliance for North American panel builds.

Questions about this item

Will the VTE18-3N8340's NPN output and 10–30 V DC supply work with my existing 24 V PLC input module?

Yes, the sensor provides an NPN switching output and operates from 10 V DC to 30 V DC, matching a typical 24 V PLC input.

How can I verify the VTE18-3N8340 is detecting correctly after mounting?

Turn the potentiometer until the output switches at the desired distance within the 10 mm to 700 mm sensing range, then confirm the dark-switching action when the beam is interrupted.

Does the VTE18-3N8340 include the M12 cable or must I order it separately?

The sensor has a 4-pin M12 male connector; the mating cable is not included and must be purchased separately.
