Description
Penny & Giles NRH300DP & NRH305DR Non-contacting Rotary Position Sensor that offer the optimal combination of performance, safety and cost.
Features of the NRH300DP & NRH305DR Non-contacting Rotary Position Sensor:
- No-contact, Hall-effect technology
- Wear free – unlimited mechanical life
- Simple mounting, low-profile design
- Measurement angle 20-360°
- 5V or 9-30V supply options
- Single or dual redundant outputs
- Analogue output – 0.5-4.5V or 0.2-4.8V
- PWM output – 244 Hz, 500Hz or 1,000 Hz
- Fail-safe outputs
- Sealing to IP69K
- Flying leads
The NRH300DP and NRH305DR utilise proven Hall-effect sensing technology in a low-profile (8mm) housing with separate magnet for true no-contact sensing.
The electrical output span can be set to correspond to rotations of 20° to 360°, and the positional information is determined by the angle of the supplied magnet relative to the sensor body. The maximum air gap between magnet and sensor is 8mm, while concentric offsets of up to 2mm can be tolerated with minimal impact on output linearity. The magnet can be supplied in a convenient carrier, housed in a bolt, as a plug or loose.
Innovative circuit design allows the NRH300DP to be powered from a regulated 5V supply or a varying voltage in the range of 9-30V, such as a vehicle’s battery. The NRH305DR supply is limited to a regulated 5Vdc supply only but includes connections for a second supply to separately power each of the two outputs, for additional redundancy and error checking.
Furthermore, both models contain on-board diagnostic functions that mean the outputs can be put into safe, pre-defined states should an internal sensor error be detected. The versatile, factory-programmable electronics can be easily set to one of two analogue voltage output ranges or one of three PWM frequencies. In addition, the polarities of each of the analogue outputs can be independently set.
The sealed design offers exceptional levels of performance with respect to water and dust, shock, vibration and temperature, meaning the sensor is ideal for use in hostile, on- and off-highway vehicle environments.
Connection to the sensor is with simple flying leads for customer termination.
The Penny & Giles product range comprises a broad selection of joysticks, sensors and solenoids for use on commercial vehicles and industrial equipment.
The products are the legacy of the Penny & Giles company founded in 1956 and acquired by Curtiss Wright in 2002.
The present-day product range includes: linear and rotary position sensors; LVDT and RVDT transducers; joysticks; studio faders; digital panel meters; and solenoid actuators for a wide range of industrial motion control applications.
Their joystick controls are suitable for commercial vehicle applications for both on- and off-highway use. These include construction and agricultural vehicles, material handling and other specialty vehicles. They are also suitable for use with industrial equipment such as robotics. Their finger-operated joystick controllers are designed for the smooth, precise control of critical functions in a variety of industrial applications where a Human-Machine Interface (HMI) is required. They also have rugged joystick controllers are designed for the more demanding installations found within operator cabs for off-highway vehicles. A wide range of linear position sensors, tilt sensors, rotary sensors, linear displacement transducers and linear potentiometers that offer distinct advantages in reliability, stability and compactness.
