SICK VTE18-3E8812 NPN photoelectric proximity sensor

This SICK VTE18-3E8812 is a cylindrical, angled photoelectric proximity sensor with an NPN switching output. It detects objects using infrared LED light at a maximum sensing range of 10 mm to 800 mm and a practical range of 10 mm to 700 mm. The sensor operates on a 10 V DC to 30 V DC supply voltage with a 2 ms response time. Its IP67 enclosure rating and –25 °C to +70 °C operating temperature suit industrial environments.

Check supply voltage and output compatibility

Verify that your control system accepts an NPN light-switching output and can provide a stable 10 V DC to 30 V DC supply with ripple below 10 %. Confirm the 2 m PVC cable with 0.14 mm² conductors and 3.1 mm diameter reaches your connection point without extension. The 60.6 mm housing dimensions and angled light emission must fit the available mounting space.

Fixed cable and potentiometer adjustment simplify

The integrated 2 m PVC cable eliminates the need for a separate connector purchase and reduces potential failure points. A built-in potentiometer allows direct sensing range adjustment without external programming tools. The plastic housing and PMMA optics resist typical industrial contaminants, while the UL file NMFT2.E175606 confirms compliance for relevant safety standards.

Questions about this item

What comes in the box and do I need to buy a mounting bracket or connector separately?

The sensor ships with a 2 m PVC cable permanently attached; no separate connector is required and no bracket is included in the package.

The specs list 700 mm and 800 mm sensing ranges — which one should I use for my setup?

Use the 700 mm figure for reliable detection; the 800 mm value is the absolute maximum under ideal conditions only.

The datasheet shows a 2 ms response time — what does that mean on a fast conveyor line?

At 2 ms the sensor can resolve objects spaced roughly 2 mm apart at 1 m/s belt speed, so it suits most packaging-line rates.
