Sick VTF18-3N5712 photoelectric sensor
The Sick VTF18-3N5712 is a cylindrical photoelectric proximity sensor with an NPN dark-switching output. It detects objects up to 45 mm using an infrared LED and offers a maximum sensing range of 50 mm. The housing measures 63.6 mm and carries an IP67 enclosure rating for harsh environments.
Check supply voltage and wiring before ordering
Verify that your system provides 10 V DC to 30 V DC with ripple below 10 % and can supply roughly 30 mA. The sensor ships with a 2 m PVC cable of 3.1 mm diameter and 0.14 mm² conductors, so ensure your terminal block or connector matches. Confirm that the –25 °C to +70 °C operating window fits the installation site.
Suits automated lines needing short-range presence
Ideal for machine builders who need a compact plastic-housed sensor with a simple potentiometer adjustment and fast 2 ms response. Not for applications requiring a complementary PNP output, light-switching logic, or a longer sensing distance than 50 mm. Buyers who need a different cable length or connector type should look at other models.

Questions about this item
Does the VTF18-3N5712 come with a mounting bracket or power supply?
The sensor ships with a 2 m PVC cable attached; no bracket or separate power supply is included.
Should I choose the 45 mm or 50 mm sensing range for my application?
The 45 mm figure is the reliable sensing range; 50 mm is the absolute maximum under ideal conditions.
What does the 2 ms response time mean on a production line?
The output switches within 2 ms of a target entering the beam, allowing detection of fast-moving objects.
