Variohm EuroSensor has increased the interfacing flexibility of its
motorsports-proven Euro-XP non-contacting angle sensor with a new 8 mm
diameter D-shaft drive option which is available with a choice of 32mm or
38mm PCD mounting.
The D-shaft with its integral magnet makes for easier installation,
particularly for throttle position sensing, without the need for a separate
coupling. With the optimal magnet to sensing-element gap maintained within
the assembly, and a choice of mounting diameters, form-fit
interchangeability with competitive models is made easy. The coupling-free
sensor is also convenient for direct connection on other motorsport position
sensing applications such as steering angle, suspension and gearbox.
The comprehensive 28 mm diameter Euro XP family, also available with Form
āUā, spring coupling or separate Puck+Magnet versions features the
motorsports industry preferred 5 VDC ratiometric output and includes a
redundant dual-track 360 degree measuring range for safety-critical use.
With two factory programmable angles from 30 to 360 degrees for both
measurement range and characteristic curve, the sensor can be configured for
a constant voltage output over pre-defined angles which is very useful for
gearbox applications. The position output covers 5% to 95% of the 5 VDC
supply voltage and being absolute, does not lose position after power loss.
The precision of the Euro XP family combines an independent linearity of +/-
0.5% of each signal range with repeatability to better than 0.2%.
The new D-shaft sensor joins the Euro XP family with completely contactless
technology and a mechanical bearing-free design with a long-life
specification in excess of 50 million movements. The fully encapsulated
sensor element ensures complete environmental protection ā rated to IP68, in
addition to IEC 60068-2-6 protection against shock and vibration.
The sensor is moulded in highly-resilient glass-filled PBT plastic with
threaded inserts and a reinforced mounting-flange with stainless steel
kidney washers that add further durability. The D-shaft material is moulded
nylon 66 and the 32mm or 38mm PCD mounting for two M4 screws includes slots
for radial adjustment. A choice of three cable exit offsets is offered and
electrical connection for the standard model is Raychem 55 cable and DR-25
sleeving at 500mm length, with connector options available on request.
