New miniature programmable angle sensor customised to order Variohm EuroSensor’s new Euro-CMRS series miniature angle sensors offer programmable angles from 30 degrees to 360 degrees in 1-degree increments in a non-contacting and long-life Hall Effect design that includes a durable IP68-sealed aluminium housing with 18mm PCD mounting and a micro 4mm diameter 316 stainless steel D-type shaft. Output options – from an industry standard 5V DC input – cover CW or CCW direction with single or dual redundant angle measurement at ratiometric or PWM signal levels. With mechanical and electrical manufacturing flexibility designed-in, the Euro-CMRS can easily accommodate customised shaft and mounting modifications as well as customer specified and other industry standard output characteristics.

The non-contacting Hall Effect sensor technology, adapted and improved for the Euro-CMRS, has been well proven in earlier Variohm sensor models as a long-life and robust measurement technology with many years of application success in performance test and development for motorsports as well as critical angular position feedback in automotive system technologies, industrial automation, agricultural and construction machinery.

The miniature sensor is less than 20mm in length with a main body diameter of just 10.5mm. Its ‘rounded diamond’ flange, measuring just 25mm × 10.5mm × 3.5mm thick, includes two 3.2mm fixing holes on an 18mm PCD to ensure straightforward yet unobtrusive mechanical interfacing to suit space-restricted installations. A 4mm diameter D-type shaft is supported in low-friction phosphor bronze sleeved bearings for a minimal drive torque requirement of just 0.8Ncm.

Variohm’s Euro-CMRS is a part of the new miniature CMRx family of Hall Effect sensor types from the company that also includes a micro-threaded interfaced version as well as a puck and separate magnet design. All boast impressive specifications that include a working temperature range from –40degC to +125degC with short-term operation to 150degC. With encapsulated sensor electronics the vibration specification meets IEC 60068-2-6.

In terms of accuracy, the independent linearity through the three models is +/- 0.5 per cent of each signal range. Standard electrical connection is 500mm long Raychem 55 cable in three- and six-wire versions to suit single and dual channel models. While the dimensions for the new CMRx miniature sensor range are the smallest currently available, their ability for straightforward design customisation and scalability is a key factor that helps ensure the customer’s installation requirements are both matched is simplified.

Variohm EuroSensor produces the Euro-CMRx range at its ISO 9001:2015 quality-certified UK manufacturing facility along with other sensor components and measurement sub-systems for position, force, pressure, load, and temperature measurement. Also, as a distributor for other sensor component suppliers and a supply chain partner for major manufacturers, the specialist provides complete sales and application support across a comprehensive range of sensor technologies for demanding measurement applications in industry, construction, agriculture, motorsports, research and more.

Variohm EuroSensor’s application engineers are on hand to discuss customer requirements and provide technical assistance from development through to after-sales support.
