New sensor
Curtiss-Wright’s Industrial division has launched the NRH300DP, a non-contact, rotary position sensor from its brand family of Penny & Giles.
With an 8mm low-profile sensor body and small footprint, this fully-encapsulated, IP68/IP69K-rated NRH300DP is said to offer high levels of performance against water, dust, shock, vibration and temperature.
It is suited for on- and off-highway vehicles destined for use in challenging environments, and as a cost-effective solution for medium volume applications where a select number of options or degree of customisation may be required.
Benefits of the NRH300DP include:
• Non-contact sensing technology provides a long mechanical life.
• Can be factory set to correspond to rotations of 20° to 360° in 1° increments.
• Industry-standard 38mm mounting centers – for easy replacement or upgrades.
• On-board diagnostic functions allow the two outputs to be put into safe, pre-defined states should an internal sensor error be detected.
Additonal features include an innovative circuit design allowing the sensor to be powered from a regulated 5V supply or a varying voltage – such as a vehicle’s battery – in the range of 9 to 30V. Versatile, factory-programmable electronics can also be easily set to one of two analog voltage output ranges (0.5-4.5V or 0.2-4.8V) or one of three PWM frequencies.
The NRH300DP uses proven, wear-free Hall-effect sensing technology and replaces the NRH280DP for new applications. It features a number of magnet arrangement options, and includes an over-molded magnet carrier that simplifies the interfacing of the magnet and sensor during installation. Optional bolt, plug or loose carrier variations are also available.
