Through-beam photoelectric sensor PNP
The Sick VS/VE18-3F3112 is a cylindrical through-beam photoelectric sensor with a PNP switching output. It operates on a 10 V DC to 30 V DC supply voltage and offers a maximum sensing range of 0 m to 20 m. The unit is designed for industrial automation tasks requiring reliable object detection.
M18 threaded housing with cable connection
Installation uses the standard M18 x 1 thread for secure mounting in a matching cut-out. The sensor comes with a pre-wired 2 m PVC cable, 3.1 mm in diameter, removing the need for a separate connector. Ensure the supply voltage stays within the 10 V to 30 V DC range and the load does not exceed 100 mA to avoid triggering the built-in circuit protection.
14 m sensing range with infrared LED
The effective sensing range reaches 14 m using an infrared LED with a 2.8° dispersion angle. At that distance the light spot grows to approximately 700 mm diameter. This range determines whether the sensor suits the application; longer distances require a different model.

Questions about this item
How do I confirm the sensor is detecting correctly after wiring it?
The sensor has a 250 Hz switching frequency and 2 ms response time. When an object breaks the infrared beam between sender and receiver, the PNP output switches high within 2 ms, which you can verify with a multimeter or PLC input LED.
What comes in the box and what must I supply separately?
The unit includes the through-beam sensor with a 2 m, 3-wire PVC cable (Ø 3.1 mm, 0.14 mm² conductors). You must provide a 10–30 V DC power supply and a mounting bracket for the M18 × 1 threaded housing.
Which sensing range figure should I use when choosing this model?
Use the 14 m sensing range for reliable detection; the 20 m maximum is the absolute limit under ideal conditions. The infrared LED produces a 700 mm spot at 14 m with a 2.8° dispersion angle.
