Why Choose the IMO VK2/A0-1B Inductive Proximity Sensor?
The IMO VK2/A0-1B is a robust and reliable inductive proximity sensor designed for non-contact detection of metal objects in industrial machinery, automation systems and control applications. As part of the IMO VK series of M18 AC inductive sensors, it combines a shielded cylindrical design with a 5 mm sensing distance and normally open TRIAC output for dependable object detection.
The VK2/A0-1B operates across a wide 20–253 V AC supply range at 50 / 60 Hz and uses a two-wire AC connection with a fixed 2 m PVC cable. Its flush-mounted M18 nickel-plated brass housing provides a practical solution for machine installations where reliable proximity detection and a compact cylindrical sensor are required.
With a nominal sensing distance of 5 mm, an operating distance of up to approximately 4.05 mm and a switching frequency of 25 Hz, the VK2/A0-1B is suitable for detecting ferrous metal targets in automated machinery. Its IP67 protection rating and −25 to +70 °C operating temperature range support use in demanding industrial environments.

Reliable Non-Contact Metal Detection
Inductive proximity sensors such as the IMO VK2/A0-1B detect metallic objects without requiring physical contact. When a suitable metal target enters the sensor's detection field, the sensor switches its output, allowing machinery and automation controllers to respond to the detected position or movement.
The VK2/A0-1B uses a shielded M18 housing for flush mounting and provides a 5 mm nominal sensing distance. Its wide 20–253 V AC supply range, normally open TRIAC output and yellow output-state LED make it suitable for a broad range of industrial sensing and control applications.
Typical Applications
- Industrial machine position detection.
- Conveyor and material handling systems.
- Automated production machinery.
- Metal object presence detection.
- Machine sequencing and control systems.
- Industrial automation and OEM machine-building applications.
