Through-beam sensor for industrial detection

The Sick VSVE18-3N3112 is a through-beam photoelectric sensor built for industrial automation tasks. It uses an infrared LED to detect objects across a sensing range of 0 m to 14 m, with a maximum reach of 20 m. The cylindrical metal housing fits an M18 x 1 thread for standard mounting. It operates on 10 V DC to 30 V DC supply voltage.

Nickel-plated brass housing with IP67 rating

The sensor body is made from nickel-plated brass and carries an IP67 enclosure rating for dust and water resistance. A 2 m PVC cable with 3-wire connection and 0.14 mm² conductor cross-section provides the electrical link. Cable diameter is 3.1 mm. Protection class III circuitry includes safeguards labelled A, B, C and D. Weight is 240 g.

NPN dark-switching output at 250 Hz

The single specification that decides fit is the NPN dark-switching output with a 100 mA maximum current and 250 Hz switching frequency. Response time is 2 ms. A test input allows the sender to be turned off by connecting TE to 0 V. Ambient operating temperature spans –25 °C to +70 °C. UL file number is NMFT2.E175606.

Questions about this item

What sensing range does the M18 through-beam sensor actually deliver in practice?

The sensor detects objects from 0 m to 14 m, with a maximum range of 20 m.

What mounting thread and clearance does the cylindrical metal housing need?

It uses an M18 x 1 thread, is 63.6 mm long, and weighs 240 g.

How do I wire the three-conductor cable and avoid the common mistake?

Connect brown to 10–30 V DC, blue to 0 V, and black to the NPN load; the dark-switching output pulls low when the beam is broken.
