Miniature rotary sensors are sealed to IP68

Paul Boughton
Contelec says that its miniaturised rotary sensors make no concessions in terms of performance compared with their larger high-end counterparts, irrespective of whether these are wire, cermet or conductive plastic-based potentiometers or contactless and non-contacting rotary sensors. The company now claims to have a complete family of angle sensors that combine ultra-compact dimensions, ruggedness, precision, resolution and modularity in a single system.
The impressive offering includes miniature rotary sensors with body diameters down to as little as 9mm, absolute and incremental versions with a measurement range of up to 360 degrees and sensors with specific output characteristics and switching functions. In addition, there are non-contacting mini angle sensors available in which the permanent magnets are attached by the customer to the rotating object. This dispenses with the need for mechanical coupling between the customer's axis and the measurement system, ensuring that no wear is caused by axial or radial forces. Miniature rotary sensors with up to 14-bit resolution and ingress protection class IP68 demonstrate that there are hardly any limits to miniaturisation.
