Cylindrical metal photoelectric sensor with angled head and M12 connector

Sick

Sick VTE18-3F2340 Photoelectric Proximity Sensor PNP

SKU CH-75J2-YNP78

Detects objects up to 200 mm using infrared light with a PNP output, IP67-rated brass housing, and M12 connector for 10–30 V DC supply

  • Detects objects up to 200 mm with infrared LED
  • Adjustable sensing range via potentiometer for flexible setup
  • PNP light-switching output integrates with standard PLCs
  • IP67 brass housing withstands dust and water jets
  • Operates from –25 °C to +70 °C in harsh environments

Industrial proximity sensor for automated detection

The Sick VTE18-3F2340 is a cylindrical photoelectric proximity sensor with a PNP switching output designed for industrial automation. It detects objects at distances from 3 mm to 170 mm using an infrared LED with a 2.8° dispersion angle. The sensor suits engineers who need reliable presence detection on conveyors or machine frames.

Low power draw and fast response in standard

The unit operates on a 10 V DC to 30 V DC supply with a maximum power consumption of 30 mA and a response time of 2 ms. Its IP67 enclosure rating protects against dust and temporary immersion while the operating temperature spans –25 °C to +70 °C. No active cooling is required and acoustic noise is negligible in normal use.

Brass housing with M12 connector for secure mounting

The sensor body uses nickel-plated brass and PMMA optics in a 75 mm cylindrical angled housing. A 4-pin M12 male connector provides a standard industrial interface for quick wiring. Light-switching mode and potentiometer adjustment are built in. Buyers needing NPN output or a different sensing range must select another model.

Questions about this item

How do I mount and wire the cylindrical VTE18-3F2340, and which step do installers often miss?

Mount the 75 mm brass nickel-plated housing, connect the 4-pin M12 male connector to a 10 V DC … 30 V DC supply, then turn the potentiometer to set the 3 mm … 170 mm sensing range; the step often missed is fine-tuning that potentiometer after power-up.

What maintenance or replacement will the VTE18-3F2340 need over time?

The IP67-rated metal and PMMA optics housing resists dust and water, so routine maintenance is limited to keeping the lens clean; the infrared LED and PNP output are solid-state with no user-replaceable parts, so the sensor itself is replaced only if it fails.

What limit appears first when the VTE18-3F2340 runs continuously in a hot environment?

The ambient operating temperature tops out at +70 °C; beyond that the 30 mA supply current and 2 ms response time can no longer be guaranteed, so thermal headroom is the first sustained-use constraint.
