Sick VTF18-3E5640 Photoelectric Sensor
This Sick VTF18-3E5640 is a cylindrical photoelectric proximity sensor designed for industrial detection tasks. It operates on a 10 V DC to 30 V DC supply with an NPN switching output. The housing uses plastic construction with PMMA optics and achieves an IP67 enclosure rating. It suits automation engineers needing reliable object detection in harsh environments.
Sensing Range and Output Type
The sensor offers a maximum sensing range of 0 mm to 50 mm and a defined sensing range of 0 mm to 45 mm using infrared LED light. Its NPN light-switching output connects via a male M12 4-pin connector. A potentiometer allows manual adjustment of the switching point. These parameters determine if the sensor fits the specific detection distance and wiring logic required.
Sustained Operation in Temperature Extremes
The unit maintains performance across an ambient operating temperature span of –25 °C to +70 °C with a response time of 2 ms. Power consumption is rated at 30 mA with a ripple tolerance of 10 %. The IP67 rating protects internal electronics from dust and water ingress during continuous duty. UL file NMFT2.E175606 confirms compliance for fixed installations.

Questions about this item
How far will the sensor reliably detect an object once it is mounted on the machine?
The sensor detects objects from 0 mm up to 45 mm in normal use, with a maximum range of 50 mm under ideal conditions.
What does the M12 4-pin connector limit in terms of wiring and voltage?
The M12 4-pin connector carries the 10 V DC to 30 V DC supply and the NPN switching output, limiting the circuit to that voltage range and a single switched signal.
What mounting clearance does the 78 mm cylindrical housing need?
The straight cylindrical housing measures 78 mm in length and requires a matching M18 threaded hole or bracket for secure installation.
