With a diminutive 10 mm diameter housing, M8 threaded mounting and a 3.175 mm diameter flatted shaft,
Variohm EuroSensor’s new Euro-CMRT series Hall Effect angle sensors extend its recently launched CMRx
range of miniature programmable non-contacting sensors. The durable and robust CMRT series has an IP68
rating and is particularly aimed at long life, high duty-cycle precision angle measurement tasks where space
is at a real premium or where its design flexibility allows straightforward mechanical and electrical adaptation
to exactly match the customer’s requirements.
A choice of single or dual redundant output, with CW or CCW
direction, includes ratiometric or PWM signal levels from an industry standard 5 VDC 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 motorsports, industrial automation, 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 will facilitate mounting in the smallest spaces as well as
allow 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, long life – in excess of 50 million
movements – is specified. A vibration rating that meets IEC 600068-2-6 and temperature range
from -40° C to +125° C, with short term operation to 150° C, further ensures performance for the
most demanding environments.
The Euro-CMRT complements the new 18 mm 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% of each signal range,
and programmable angles from 30⁰ to 360⁰ in 1⁰ increments. Electrical connection for the 3-wire
single-channel and 6-wire dual-channel versions is 500 mm long Raychem 55 cable with
connectors and other options on request. Across the new CMRx micro sensor range, whilst 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 leading 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-contacting 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
