Sick VTE18-4N2412 Photoelectric proximity sensor NPN

Sick VTE18-4N2412 Photoelectric Sensor

The Sick VTE18-4N2412 is a cylindrical photoelectric proximity sensor with an NPN switching output. It suits automation engineers and electricians who need reliable object detection at short range on conveyors or packaging lines. The sensor operates on 10 V DC to 30 V DC supply voltage and delivers a switching frequency of 250 Hz. Its metal nickel-plated brass housing meets IP67 enclosure rating for harsh industrial environments.

M18 Threaded Installation And Cable Wiring

Mounting uses the standard M18 x 1 thread with a housing length of 60.6 mm, allowing direct fit into existing brackets. A 2 m PVC cable with four wires and 0.14 mm² conductor cross-section carries power and signal connections. The potentiometer provides 270° adjustment for sensing range between 3 mm and 170 mm. Incorrect wiring of the L/D control cable reverses light/dark switching logic, which is the most common setup error.

Check Supply Voltage And Output Compatibility

Verify that your control system accepts an NPN output with a maximum load current of 100 mA before ordering. The sensor requires a DC supply between 10 V and 30 V with ripple below 10 %. Ensure the ambient operating temperature stays within –25 °C to +70 °C at the mounting location. Confirm that the 2 m cable length and radial optical axis orientation match your machine geometry.
