Cylindrical angled brass sensor with 2 m PVC cable

Sick

Sick VTE18-3E8312 photoelectric proximity sensor NPN

SKU CH-Q5FS-RPDQB

Detects objects from 10 to 700 mm using infrared LED with NPN output and IP67 metal housing

  • NPN light-switching output simplifies wiring for PLC inputs
  • 10 mm to 700 mm sensing range covers close and mid-range detection
  • IP67 brass housing resists water jets and dust in harsh areas
  • 2 ms response time catches fast-moving targets reliably
  • 2 m PVC cable with 0.14 mm² conductors enables direct installation

Sick VTE18-3E8312 photoelectric sensor

The Sick VTE18-3E8312 is a cylindrical photoelectric proximity sensor with an NPN switching output. It suits automation engineers and maintenance technicians who need reliable object detection in industrial environments. The metal brass housing and IP67 rating allow installation in areas exposed to dust, coolant or temporary immersion. It operates on a 10 V DC to 30 V DC supply with a 2 m PVC cable.

Sensing range up to 700 mm

The sensor detects objects from 10 mm to 700 mm using an infrared LED with a 2.8° dispersion angle. A potentiometer provides manual adjustment of the switching threshold for the application. Light-switching mode means the output activates when the beam is reflected back to the receiver. Response time is 2 ms, suitable for medium-speed conveyors or packaging lines.

Cable connection with potentiometer adjust

The 2 m PVC cable has a 0.14 mm² conductor cross-section and 3.1 mm outer diameter, terminating in flying leads for direct wiring into terminal blocks. Brass nickel-plated housing resists mechanical impact and chemical splash. Installers must ensure the supply voltage stays within 10 V DC to 30 V DC with ripple below 10 % to avoid erratic switching. The sensor is not for applications requiring PNP output or connectorised M12 termination.

Questions about this item

What does the 10 mm to 700 mm sensing range mean when the sensor is mounted on a production line?

The sensor will reliably detect objects between 10 mm and 700 mm from its face; beyond 700 mm up to 800 mm detection is possible but not guaranteed.

How does the 10 V DC to 30 V DC supply range limit the power sources I can use?

Any DC supply between 10 V and 30 V with less than 10 % ripple and at least 30 mA capacity will power the sensor; voltages outside that range are not supported.

What clearance does the 60.6 mm cylindrical housing and 2 m PVC cable need for installation?

The metal barrel is 60.6 mm wide and the 3.1 mm diameter cable requires a bend radius that avoids kinking; allow space for the angled light exit and the potentiometer adjuster.
