SICK VTF18-4P1312 photoelectric proximity sensor
The SICK VTF18-4P1312 is a cylindrical photoelectric proximity sensor with an angled light emission. It operates on a 10 V DC to 30 V DC supply and provides a PNP switching output. The sensor is intended for industrial automation tasks where reliable object detection is required. Its metal brass nickel-plated housing and IP67 enclosure rating suit harsh environments.
Sensing range and electrical limits
The sensor detects objects from 3 mm up to a maximum of 100 mm using infrared LED light. A potentiometer allows adjustment of the sensing range up to 90 mm. The response time is 2 ms and power consumption is 30 mA with a 10 % ripple tolerance. Connection is via a 2 m PVC cable with 0.14 mm² conductor cross-section and 5 mm diameter.
Upgrade from basic limit switches
This sensor replaces mechanical limit switches in applications needing non-contact detection and faster switching. The jump is worthwhile when dust, vibration or moisture cause mechanical contacts to fail, or when wear-free operation reduces maintenance. It is not suited for applications requiring detection beyond 100 mm or for environments exceeding the –25 °C to +70 °C operating temperature range.

Questions about this item
How do I choose between the 3 mm to 90 mm sensing range and the 3 mm to 100 mm maximum range for my application?
Use the 3 mm to 90 mm range for reliable detection; the 3 mm to 100 mm figure is the absolute maximum under ideal conditions.
What does the 2 ms response time mean when the sensor is installed on a production line?
The output switches within 2 ms of a target entering or leaving the beam, allowing detection of fast-moving objects.
What does the PNP switching output with 10 V DC to 30 V DC supply voltage cap in practice?
It delivers a high-side signal up to the supply rail, limited to 30 mA current draw and a 2 ms switching speed.
