Industrial photoelectric sensor for automation

The Sick VTE18-3E8340 is a cylindrical photoelectric proximity sensor with NPN switching output. It detects objects using infrared LED light across a sensing range of 10 mm to 700 mm. The metal and plastic housing achieves an IP67 enclosure rating for harsh industrial environments. This unit suits machine builders and maintenance engineers who need reliable presence detection.

Check supply voltage and connector compatibility

Verify that your control system provides 10 V DC to 30 V DC with ripple below 10 percent. The sensor draws 30 mA and connects via a male M12 4-pin connector. Ensure the switching mode matches your light-switching logic and that the 2 ms response time meets cycle-time requirements. Confirm the operating temperature range of –25 °C to +70 °C covers the installation site.

Brass nickel-plated housing with angled optics

The brass nickel-plated metal body and PMMA plastic optics resist mechanical stress and chemical exposure. An angled light-emission design allows flexible mounting in tight spaces while the 2.8° dispersion angle keeps the beam focused. A potentiometer on the housing enables quick range adjustment without tools. The IP67 rating means daily wash-downs and coolant spray will not affect operation.

Questions about this item

What comes with the VTE18-3E8340 sensor and what must I buy separately?

The sensor has a 4-pin M12 male connector built in. You will need a matching 4-pin M12 cable or plug, which is sold separately. No mounting hardware is included.

How do I choose between the 700 mm and 800 mm sensing ranges?

The 700 mm figure is the reliable sensing range under normal conditions. The 800 mm figure is the absolute maximum under ideal reflectivity; use 700 mm for consistent detection.

What does the 2 ms response time mean on a production line?

The sensor switches its NPN output within 2 ms of detecting an object, so it can reliably register parts moving at typical conveyor speeds without missing counts.
