Curtiss-Wright's Industrial division launched a new non-contact, rotary position sensor under its Penny & Giles brand. Using wear-free Hall-effect sensing technology, the NRH300DP replaces the NRH280DP for new applications.
The NRH300DP non-contact rotary position sensor, from Penny & Giles (a unit of Curtiss-Wright's Industrial division). Image source: Curtiss-WrightWith an 8mm low-profile sensor body and a small footprint, this fully-encapsulated, IP68/IP69K-rated sensor offers, in its maker's assessment, exceptional levels of performance against water, dust, shock, vibration and temperature. The company positions the NRH300DP as ideal for use by OEMs of on- and off-highway vehicles that are 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 customization may be required.
Benefits of the new NRH300DP rotary position sensor include:
- Non-contact sensing technology for a long mechanical life
- Can be factory set to correspond to rotations of 20° to 360° in 1° increments
- Industry-standard 38 mm mounting centers allow easy replacement or upgrades
- On-board diagnostic functions permit the two outputs to be put into safe, pre-defined states should an internal sensor error be detected
The NRH300DP can be powered from a regulated 5 V supply or a varying voltage — such as a vehicle's battery — in the range of 9 V to 30 V. The factory-programmable electronics can also be easily set to one of two analog voltage output ranges (0.5 V to 4.5 V or 0.2 V to 4.8 V) or one of three pulse-width modulation (PWM) frequencies.
The new design features a number of magnet arrangement options, and includes an over-molded magnet carrier that simplifies interfacing the magnet and sensor during installation. Optional bolt, plug or loose carrier variations are also available.
