Easier angle measurement in confined spaces

Confined spaces, difficult environments and price sensitivity; with a combination of these factors, angle measurement becomes a demanding undertaking. Applications requiring reliable, accurate angle measurement in harsh operational environments - such as agricultural and municipal vehicles, buses, fork lift trucks, grain mills and railway equipment - place heavy demands on suppliers of rotary encoders. The challenge is to develop innovative systems that are characterised by compact dimensions, refined design, intelligent installation capabilities, high protection rate and ruggedness. On top of this, the rotary encoders are expected to meet exacting precision and service-life requirements without being expensive.

The Vert-X 05E angle sensor, available exclusively from Variohm EuroSensor in the UK, offers value for money and, with its ultra-compact size and physical architecture, can be used in confined spaces. Potted with a high-grade, temperature-resistant epoxy resin, it is impervious to contamination. With IP68 protection and an operating temperature range of -40degC to +125degC, it copes easily with harsh environments.

In non-contacting magnetic rotary encoders, the sensor unit and magnetic actuator are physically separated. This brings a high level of resistance to shock and vibration and enables accurate measurements to be made - even with considerable axial and radial offsets between the sensor and actuator.

Features

Just 5mm high, the very slim angle sensor is unusually compact, with its measurement system only 6mm from the edge. This enables the Vert-X 05E to be used in applications with a rotation centre close to a wall.

It is easy to select the sense of rotation: the Vert-X 05E angle sensor can simply be installed either way round for clockwise or counter-clockwise angle measurements, with no need to program the angle sensor.

The non-contacting measuring principle also enables measurements to be made through non-magnetic materials (liquids or solids).

A fully redundant version of the Vert-X 05E angle sensor is also available for mission-critical or safety-related applications.
