SICK VTE18-3E8640 Photoelectric Proximity Sensor NPN

SKU CH-FGFS-T32S8

Photoelectric proximity sensor detects objects from 10 mm to 700 mm with an NPN output, IP67-rated cylindrical plastic housing, and M12 connector for 10–30 V DC supply

  • Detects objects up to 800 mm away with infrared LED
  • Adjustable sensing range from 10 mm to 700 mm via potentiometer
  • Fast 2 ms response time suits high-speed automation
  • IP67-rated plastic housing withstands dust and water immersion
  • Operates on 10–30 V DC with NPN light-switching output

Industrial Detection Sensor

The SICK VTE18-3E8640 is a cylindrical photoelectric proximity sensor designed for industrial automation tasks. It operates on 10 V DC to 30 V DC supply voltage with an NPN switching output and light switching mode. The housing uses plastic construction with PMMA optics and achieves an IP67 enclosure rating for harsh environments.

Upgrade From Basic Switches

This sensor replaces mechanical limit switches or basic inductive sensors where non-contact detection at longer ranges is required. The jump is worth it when the application demands a sensing range up to 700 mm with infrared LED emission and a 2.8° dispersion angle. Potentiometer adjustment allows fine-tuning for specific target distances.

M12 Connector Constraints

The male M12 4-pin connection type dictates the cabling infrastructure needed for integration. Response time is rated at 2 ms, which sets the practical limit for high-speed detection cycles. Operating temperature spans –25 °C to +70 °C, defining the environmental envelope for reliable operation.

Questions about this item

What thread size does the cylindrical housing need for mounting?

The cylindrical housing measures 78 mm in diameter and is designed for M18 mounting threads.

How do I wire the M12 connector and set the sensing distance correctly?

Connect the 4-pin M12 plug to a 10 V DC to 30 V DC supply, then turn the potentiometer until the infrared beam detects objects between 10 mm and 700 mm.

When should I clean or replace the PMMA optics cover?

Wipe the PMMA optics whenever dust or oil reduces the 2.8° infrared beam; replace the sensor if the IP67 seal fails or the NPN output no longer switches within 2 ms.
