  • IP67-rated plastic housing withstands –25 °C to +70 °C
  • 2 m PVC cable with 0.14 mm² conductors simplifies wiring

Sick VTF18-3E5812 Photoelectric Sensor

The Sick VTF18-3E5812 is a cylindrical photoelectric proximity sensor designed for industrial automation and machine-building applications. It detects objects using an infrared LED light source and provides an NPN switching output for direct integration with programmable logic controllers. The housing is made of plastic with PMMA optics and carries an IP67 enclosure rating for harsh environments.

NPN Switching Output and 45 mm Sensing Range

The decisive specification is the NPN light-switching output combined with a maximum sensing range of 45 mm. This output type sinks current to the negative rail, so the load must be connected between the output and the positive supply voltage. Buyers whose control systems require a PNP sourcing output or a sensing distance beyond 45 mm cannot use this sensor.

Stable Operation Across Wide Temperature Span

The sensor operates continuously from –25 °C to +70 °C with a supply voltage of 10 V DC to 30 V DC and a response time of 2 ms. Power consumption remains at 30 mA during sustained use. The 2 m PVC cable with 0.14 mm² conductors maintains signal integrity over the full temperature range without the drift that can affect shorter-burst testing.

Questions about this item

How far can the sensor actually detect an object once it is mounted in a machine?

The usable sensing range is 0 mm to 45 mm, while the absolute maximum reaches 50 mm under ideal conditions.

What does the 10 V DC to 30 V DC supply range limit in practice?

It requires a DC source within that window with no more than 10 % ripple; the sensor draws up to 30 mA.

What physical space and mounting features does the cylindrical angled housing need?

The housing measures 60.6 mm overall, uses a 2 m PVC cable of 3.1 mm diameter, and meets IP67 for dust and water protection.
