Sick VTF18-3E1112 NPN proximity sensor
The Sick VTF18-3E1112 is a cylindrical photoelectric proximity sensor with background blanking and an NPN switching output. It operates on a 10 V DC to 30 V DC supply and provides a sensing range of 3 mm to 90 mm with a focused infrared LED spot. The sensor is suited for industrial automation tasks requiring reliable object detection at short distances.
Check supply voltage and output compatibility
Verify that your control system accepts an NPN light-switching output rated at 100 mA maximum and a 10 V DC to 30 V DC supply with ripple below 10 %. Ensure the M18 x 1 thread matches the mounting hole and that the 2 m PVC cable with 0.14 mm² conductors can be routed to the termination point. The IP67 enclosure rating and –25 °C to +70 °C operating range suit harsh environments.
Ideal for short-range presence detection
This sensor suits machine builders who need a compact metal-housed device with focused optics for precise detection up to 90 mm. It is not for applications requiring adjustable sensing distance, PNP output logic, or connectorised wiring. Buyers needing longer range, teach-in adjustment, or a different output type should consider other sensor families.

Questions about this item
Does the sensor come with a mounting bracket or do I need to buy one separately?
The sensor has an M18 x 1 threaded metal housing for direct mounting; no bracket is included in the box.
The sensing range shows 3 mm to 100 mm maximum and 3 mm to 90 mm standard — which figure should I design for?
Design for the 3 mm to 90 mm sensing range; the 100 mm maximum applies only under ideal conditions with a bright background.
The response time is 2 ms and switching frequency 250 Hz — what does that mean for a conveyor moving at speed?
At 250 Hz the sensor can reliably detect objects passing every 4 ms, so it suits conveyors with object spacing above that interval.
