Sick VTF18-3F5340 Photoelectric Proximity Sensor PNP

SKU CH-87KS-7ZCPS

Photoelectric proximity sensor detects objects up to 50 mm with PNP output and IP67-rated metal housing

  • Reliable detection up to 45 mm with infrared LED
  • Adjustable sensing distance via built-in potentiometer
  • Fast 2 ms response for quick switching
  • Rugged IP67-rated brass housing withstands harsh environments
  • Wide 10–30 V DC supply fits many systems

SICK VTF18-3F5340 Proximity Sensor

The SICK VTF18-3F5340 is a photoelectric proximity sensor with a PNP switching output. It uses an infrared LED light source to detect objects within a sensing range of 0 mm to 45 mm, extending to a maximum of 50 mm. The cylindrical, angled housing measures 75 mm and is constructed from nickel-plated brass and plastic. It operates on a 10 V DC to 30 V DC supply voltage with a power consumption of 30 mA.

Installation and Common Issues

Connection is made via a male M12 4-pin connector, requiring a compatible cable or cordset. The sensor features a potentiometer for adjusting the switching threshold to suit the application. Its IP67 enclosure rating protects against dust and temporary immersion, while the metal housing withstands industrial environments. Ensure the supply voltage stays within the 10 V DC to 30 V DC range and that the 2 ms response time meets the timing requirements of the control system.

Ideal Users and Limitations

This sensor suits automation engineers and maintenance technicians needing reliable object detection in packaging, assembly or material handling equipment. The light switching mode activates the output when the beam is received. Buyers who need a dark switching mode or an NPN output type should look at alternative models. Applications requiring a sensing distance beyond 50 mm or a different housing form factor will need a different sensor class.

Questions about this item

How do I verify the sensor is detecting correctly after wiring the M12 4-pin connector?

With 10 V DC to 30 V DC applied, the PNP output switches high when an object enters the 0 mm to 45 mm sensing range; use the potentiometer to set the exact switching point and watch the target LED indicator.

What comes in the box and what must I purchase separately?

The sensor housing with integrated M12 4-pin male connector is supplied; a compatible M12 4-pin cable or field-wireable connector and a 10 V DC to 30 V DC power supply are not included.

Which sensing distance version should I choose for reliable detection up to 45 mm?

This model provides a maximum sensing range of 0 mm to 50 mm and a guaranteed operating range of 0 mm to 45 mm; select it when your application requires detection within that 45 mm window.
