Rugged - flat rotary sensors for confined installation space

With its Vert-X 90E model, Contelec is launching a flat, heavy-duty non-contacting rotary sensor, which is particularly suitable for mobile applications. With a height of just 12 mm, ingress protection class IP69K and high shock and vibration resistance, the Vert-X 90E can be used in confined spaces in applications on construction and forestry machinery, concrete pumps and fire service vehicles, which make exacting demands in terms of ruggedness, stability and environmental conditions.

An important factor is that there is no direct mechanical linkage in the Vert-X 90E between the rotating axis and the actual measurement system. On the non-contacting rotary sensor, the permanent magnet is attached to the rotating object. This ensures that it is possible to make precise measurement - even with radial and axial offsets of several millimetres. In addition, axially and radially acting forces cause no wear. These features make the rotary sensor ideal for use in cases where the rotating object is outside a certain tolerance range or when physical contact between the rotary sensor and object is not possible.

The Vert-X 90E rotary sensor is based on innovative Vert-X MH-C2 technology, which enables extremely easy user setting of indexing points (e.g. zero point) and direction of rotation. This in turn allows fast, convenient installation, while permitting elegant compensation for the equipment tolerances and installation tolerances of the rotary sensor. Another significant factor is the high degree of flexibility of the Vert-X MH-C2 rotary sensor, offering the possibility of integration of different analogue and digital interfaces.
