Industrial proximity sensor
The Sick VTF18-3N5840 is a photoelectric proximity sensor with an NPN switching output designed for industrial automation tasks. It detects objects using infrared LED light within a cylindrical angled housing measuring 75 mm. The unit operates on a 10 V DC to 30 V DC supply voltage with a maximum power consumption of 30 mA. It suits engineers integrating presence detection into conveyor or packaging lines.
Build integration details
The sensor connects via a male M12 4-pin connector requiring a compatible cable assembly for power and signal. Its plastic housing and PMMA optics achieve an IP67 enclosure rating for dust and water resistance. The sensing range reaches up to 50 mm with a usable range of 45 mm, adjustable via an onboard potentiometer. Dark switching mode activates the output when the beam is interrupted.
Sustained operation behaviour
Response time is rated at 2 ms, allowing reliable detection in continuous cycling applications. The device maintains performance across an ambient operating temperature span of –25 °C to +70 °C. Ripple tolerance is specified at 10 % on the supply line. UL file NMFT2.E175606 confirms compliance for relevant safety standards.
