New family of rotary position sensors
The Industrial division of Curtiss-Wright Corporation 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 customisation may be required.
• The NRH271 is a 3-wire, single output variant with a supply current rating of less than 12.5mA.
• The NRH272 is a 6-wire, dual-redundant output variant with a supply current rating of less than 25mA. The dual-die sensor has two separately powered input supply and output channels for full electrical redundancy.
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 20deg to 360deg in 1deg increments. Two power supply options are available (5V and 9-30V). Factory-programmable electronics can be set to one of two analogue 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.
