Curtiss-Wright Extends Rotary Sensor Family

Christchurch, U.K. – Curtiss-Wright’s Industrial division today announced the launch of the NRH305DR, a new ‘no-contact’ rotary position sensor that extends the company’s portfolio of position sensors and offers an optimal combination of performance, safety and cost for OEMs designing vehicles and control systems.

Sharing many of the same features and benefits as the NRH300DP model launched in 2016, the new NRH305DR rotary position sensor – from the Penny & Giles brand family – enhances system performance by incorporating two completely independent power supplies and output channels for full electrical redundancy, operating from a 5Vdc regulated supply.

With an 8mm low-profile sensor body and small footprint, this fully-encapsulated, IP68/IP69K-rated sensor offers exceptional levels of performance against water, dust, shock, vibration and temperature. The separate magnet assembly that activates the sensor can have a permissible air gap between 1.5mm and 8mm (depending on magnet style) and can accommodate up to ±2mm radial offset to ease setup and installation.

Versatile, factory-programmable electronics can be easily set to one of two analog voltage output ranges or one of three PWM frequencies. Additionally, the polarities of each of the analog outputs can be independently set, with on-board diagnostic functions ensuring the outputs are put into safe, pre-defined states should an internal sensor error be detected.

Features and benefits of the NRH305DR include:

  • No-contact design and sensing technology provides wear-free operation
    • 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
    • Analog output from 0.5-4.5V or 0.2-4.8V
    • Transmissive measurements can be made through non-magnetic materials

The new NRH305DR – which replaces the company’s legacy NRH285DR rotary position sensor – uses proven, wear-free Hall-effect sensing technology. The design 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.
