Novotechnik SP1600 and SP4000 angle sensorsVariohm EuroSensor is introducing the Novotechnik SP1600 and SP4000 angle sensors; these potentiometric devices are claimed to have exceptional price/performance ratios through high-volume manufacture that provides considerable economies of scale.

With an electrical measurement angle of around 100 degrees, the SP1600 and SP4000 angle sensors are both produced in large quantities for high-reliability automotive position feedback applications. However, their simplicity in design and highly durable construction enables them to be used in extreme environments such as agricultural machinery, construction equipment or demanding industrial machines.

Both models feature Novotechnik's well proven potentiometric sensor technology with conductive plastic resistance elements and precious metal multi-finger wipers that ensure contact even under the most arduous conditions. With high-grade and temperature-resistant moulded plastic housings, these sensors feature hollow shaft couplings and O-ring seals for protection to IP67. Each design includes an internal return spring and requires a customer-side drive shaft and support bearing arrangement.

Simple integration

While the main environmental specifications for both models are relatively similar, the mechanical design differs in terms of the orientation of the measurement angle and the built-in three-pin electrical connector. For the SP1600, the sensor housing is secured with a single oval slot, whereas the SP4000 includes two brass bushings.

The SP1600 offers a 105-degree nominal electrical angle with a 5kohm nominal resistance and up to 24V DC supply. The SP4000 has a 101-degree nominal electrical angle, a 1.2kohm resistance and up to 16V DC supply. Both high-accuracy sensors feature an absolute linearity of +/-2 per cent VDD with repeatability to within one degree.

Variohm says the SP1600 and SP4000 are designed to operate in harsh environmental conditions, close to automotive engines and gearboxes with temperature extremes and high levels of shock and vibration.

Thanks to the modular construction of the Novotechnik design, custom versions of both sensors, with different electrical angles or mechanical interfacing, are available on request.

Novotechnik has recently received a Supplier of the Yea award from a major automotive component manufacture for a throttle position sensor that has achieved 50million parts supplied with zero field failures. The new angle sensors are part of a wide range of Novotechnik contacting and non-contacting linear and angular position sensors available exclusively in the UK and Ireland from Variohm EuroSensor.
