Miniature programmable Hall effect angle sensor is smallest yet
With a diminutive 10mm diameter housing, M8 threaded mounting and a 3.175mm diameter flatted shaft, Variohm EuroSensor's new Euro-CMRT series Hall effect angle sensors extend the company's recently launched CMRx range of miniature programmable non-contacting sensors. The durable and robust CMRT series has an IP68 rating and is aimed at long-life, high duty-cycle precision angle measurement tasks where space is at a premium or where its design flexibility allows straightforward mechanical and electrical adaptation to match the application's requirements. A choice of single or dual redundant outputs, with CW or CCW direction, includes ratiometric or PWM signal levels from an industry-standard 5V DC input.
Variohm's Hall effect sensor technology has been adapted and improved over many angle sensor design iterations and is well-proven for use in arduous position feedback measurement applications that include industrial automation, motorsport, agricultural vehicles and construction machinery. And now the new Euro-CMRT series is available in its smallest package size to date. The M8 mounting and small envelope facilitate mounting in confined spaces, as well as allowing for custom flange adaptations for form-fit replacements for competitor products and application upgrades for existing Variohm applications.
The high-grade anodised aluminium housing supports the 316 stainless steel shaft in a durable phosphor bronze sleeve bearing, and with no sensor contact, a long life can be expected - in excess of 50 million movements. A vibration rating that meets IEC 600068-2-6 and operating temperature range from -40C to +125degC, with short-term operation to 150degC, further ensures reliable performance in demanding environments.
Performance characteristics
The Euro-CMRT complements the new 18mm PCD flange-mounting Euro-CMRS and the puck-and-magnet design of the Euro-CMRK. Thanks to their innovative and modular design, with encapsulated sensor electronics, all Euro-CMRx series products boast the same impressive environmental and electrical specifications with independent linearity to 0.5 per cent of each signal range, and programmable angles from 30 degrees to 360 degrees in 1 degree increments. Electrical connection for the three-wire single-channel and six-wire dual-channel versions is 500mm long Raychem 55 cable with connectors and other options on request. Across the new CMRx micro sensor range, while the dimensions are the smallest currently available, the modular design offers straightforward mechanical and electrical customisation. This scalability helps to ensure the customer's installation requirements are both matched and simplified.
The Euro-CMRx range is produced at Variohm's ISO 9001:2015 quality-certified UK manufacturing facility, along with many other precision sensor components and measurement sub-systems for position, force, pressure, load and temperature measurement. Variohm is also a distributor for several other sensor component suppliers, as well as a supply chain partner for major manufacturers. The specialist provides complete sales and application support across its comprehensive range of sensor technologies for demanding measurement applications in industry, construction, agriculture, motorsports, research and more.
A new datasheet is available covering the Euro-CMRT, along with complete specification details for the new Euro-CMRx range of customisable Hall effect non-contact sensor models on the Variohm EuroSensor website. Variohm EuroSensor's application engineers are on hand to discuss customer requirements and provide technical assistance from development through to after-sales support.
