Industrial photoelectric sensor
The Sick VTF18-3P5340 is a cylindrical photoelectric proximity sensor with an angled light emission design. It uses an infrared LED source and a potentiometer for adjustment. The sensor provides a PNP dark-switching output through a male M12 four-pin connector. It suits automation tasks requiring non-contact object detection within short range.
Thermals noise and power
The unit operates on a 10 to 30 V DC supply with a maximum ripple of 10 percent and a power consumption of 30 mA. Its metal brass nickel-plated housing with plastic components meets IP67 enclosure rating for dust and water protection. The operating temperature spans from minus 25 to plus 70 degrees Celsius. No audible noise is generated by the solid-state electronics.
Sustained load behaviour
The sensor delivers a consistent response time of 2 ms across the defined sensing range of up to 45 mm and a maximum range of 50 mm. The optics use PMMA plastic material. The UL file number NMFT2.E175606 confirms compliance for industrial environments. It is not suited for applications needing longer detection distances or alternative output types.

Questions about this item
How do I wire the M12 4-pin connector so the PNP output works with my 10 V DC to 30 V DC supply?
Connect pin 1 to positive supply, pin 3 to negative, and take the switched load from pin 4; pin 2 is unused on this dark-switching model.
What part of the sensor is most likely to need cleaning or replacement after extended use?
The PMMA plastic optics window should be inspected regularly; dust or scratches on it reduce the 45 mm sensing range before any electronic fault appears.
At what ambient temperature does the sensor stop meeting its IP67 rating during continuous operation?
The enclosure rating holds across the full –25 °C to +70 °C operating range; temperature alone does not degrade the IP67 seal.
