SICK VL18-3E3440 photoelectric sensor

The SICK VL18-3E3440 is a cylindrical photoelectric retro-reflective sensor with an angled light emission design. It operates on a 10 V DC to 30 V DC supply voltage and provides an NPN switching output with light switching mode. The housing uses nickel-plated brass and plastic with an IP67 enclosure rating for industrial environments.

Suits 3.7 m range detection with visible red LED

This sensor suits applications needing a maximum sensing range of 0.05 m to 3.7 m using a visible red LED with a 2.8° dispersion angle. A potentiometer allows range adjustment. Builders who need a different output type, connection format, or longer range than 3.7 m should look at other models.

M12 4-pin connector decides fit

The single specification that decides fit is the male M12 4-pin connection type. Your wiring harness must match this exact connector to install the sensor. Verify the pinout and cable availability before purchase.

Questions about this item

How can I verify the Sick VL18-3E3440 sensor is working correctly after installation?

Apply 10 V DC to 30 V DC supply voltage, align the visible red LED beam with the reflector, and confirm the NPN output switches within 2 ms when the beam is interrupted.

What comes in the box with the Sick VL18-3E3440 and what must I purchase separately?

The sensor housing with M12 4-pin male connector is included; a compatible M12 cable, reflector, and 10 V DC to 30 V DC power supply must be bought separately.

Which sensing range version of the VL18-3E3440 should I choose for my application?

This model offers a maximum sensing range of 0.05 m to 3.7 m and a standard range of 0.05 m to 3 m; select based on the required detection distance.
