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.
Robust JC1200 single-axis joystick has a long operating life
Curtiss-Wright Corporation today announced its Industrial division has launched the JC1200, a next-generation, cost-effective paddle joystick from the Corporation’s brand family of Penny & Giles.
By using a long-life bearing system and non-contacting Hall-effect sensing technology, the JC1200 has achieved a long operating life of 25 million cycles while providing functionality that is smooth and easy to operate.
Key features of the JC1200 include:
- An under-panel depth of 9mm, requiring minimal installation space
- A spring-loaded return-to-center or return-to-end paddle movement
- Integrated panel seal and IP67 protection – suitable for outside use
- A choice of nine colored paddle ‘Tabs’, which can be factory fitted or supplied separately and added as part of the final customer installation process
The JC1200 launches with a 5Vdc supply voltage and the option for factory-programmable electronics configured to one of two analog voltage output ranges (0.5-4.5V or 1.0-4.0V). The joystick also provides safety functionality via dual outputs, which can be set to positive or negative ramps, or a combination of both. This offers system designers the option to compare the output signals for error checking.
The JC1200 paddle joystick builds on the success of the potentiometric-based JC120 and is ideal for use in control panels and armrests found in industrial trucks, agricultural equipment and construction machinery, where cost-effective, long-life operator controls are essential.

Curtiss-Wright Corporation (NYSE: CW) today announced that its Industrial division has launched a new family of non-contact, rotary position sensors from the legacy brand of Penny & Giles. With a low-profile sensor body design and a small footprint, these fully-encapsulated, IP69K-rated sensors offer exceptional performance against water, dust, shock, vibration, and temperature. The NRH271 and NRH272 rotary position sensors are 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 wide range of options or degree of customization may be required.
All variants of the NRH271 and NRH272 rotary position sensors are contained in a 9.5mm housing and use proven, wear-free Hall-effect sensing technology to provide a long mechanical life. The electrical output spans of both models can be set to correspond to rotations of 20° to 360° in 1° increments. Two power supply options are available (5V and 9-30V). Factory-programmable electronics can be set to one of two analog voltage output ranges (0.5-4.5V or 0.2-4.8V) or one of three PWM frequencies.
Connection options are industry-standard AMP Superseal or Deutsch DT04 series connectors, or simple 18AWG flying-leads for customer termination. The sensor can also be supplied with a protective NC10 flexible conduit for the cabling.

Curtiss-Wright Corporation (NYSE: CW) today announced that its Industrial division has expanded the functionality of its R-net multi-module control system for rehab-type powerchairs, with the introduction of the R-net Gyro Module from PG Drives Technology.
The R-net Gyro Module adds an extra dimension to controlling a wheelchair by maintaining the desired drive direction irrespective of the external forces acting on the wheelchair.
Commenting for Curtiss-Wright, Senior Vice President & General Manager of the Industrial division, Kevin Rayment says: “High-speed, front-wheel-drive type wheelchairs will benefit most from the addition of the R-net Gyro Module; however the technology also offers vastly improved drive performance on rear-wheel-drive models when used with switch-type specialty controls.”
A particularly difficult issue with some fast, front-wheel-drive wheelchairs is experienced on exiting a turn when, regardless of the joystick’s position, the wheelchair can continue to turn and enter a ‘spin-out’ condition. Existing, software-based solutions have attempted to address this by slowing the wheelchair’s turning speed by a set amount, but this often results in a poor drive feel. The R-net Gyro Module offers a more reactive result by only reducing the turning speed of the wheelchair by as much as is necessary. This results in a more responsive and smoother drive feel, as the wheelchair does not need to be slowed down dramatically to maintain control.
When driving in a straight line, there may be a tendency for the wheelchair to veer to one side or the other, a condition known as fish-tailing. The Gyro Module can effectively eliminate all of these conditions. Additionally, if a wheelchair is driving across a non-level surface – e.g. a camber – the user has to make frequent steering corrections to achieve a straight line driving. This is inconvenient when using a joystick, but becomes increasingly difficult when using a switch-type controlling device such as a switch pad or head array. A further challenge in maintaining straight line driving is presented by obstacles, such as a pavement kerb, or door thresholds, particularly if they are of uneven height. The Gyro Module vastly improves control in all of these situations.
The Module includes two gyro sensors as standard. This means that if one sensor becomes defective the other maintains control. In the event of a complete gyro failure or module disconnection, the wheelchair’s drive speed is automatically limited.
The compact size of the R-net Gyro Module from PG Drives Technology means it can be easily accommodated on any wheelchair. Its ability to be mounted in one of four orientations also means fitting and setup is intuitive and simple. The R-net Gyro Module has also been designed to work with existing R-net Modules; and all Power Modules will be upgraded to support gyro functionality as standard.
Curtiss-Wright’s Industrial division is a recognized leader in the production of critical controls and assemblies for specialty vehicles, including sensors, electronic throttle controls and joysticks. Its PG Drives Technology business has almost 40 years’ experience in sophisticated mobility control systems and is one of the world’s foremost suppliers of these products.
