Rotary position sensors feature small footprint

Curtiss-Wright has announced that its Industrial division has launched a family of non-contact, rotary position sensors from the 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 suitable 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 three-wire, single output variant with a supply current rating of less than 12.5mA.The NRH272 is a six-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 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 analogue voltage output ranges (0.5-4.5V or 0.2-4.8V) or one of three PWM frequencies.

Connection options include industry-standard AMP Superseal or Deutsch DT04 series connectors, or simple 18AWG flying-leads for customer termination. The sensors can also be supplied with a protective NC10 flexible conduit for the cabling.
