NRH285DR Dual Redundant Output 'No Contact' Rotary Position Sensor
Penny+Giles announces a new dual redundant output, no-contact rotary position sensor with the slimmest low profile housing, using a factory programmable Hall effect sensor system.
NRH285DR operates from a 5Vdc (±0,5) regulated supply to each independent sensor channel, and has two independent outputs, enabling full redundancy from a very slim package.
NRH285DR has a co-moulded fully encapsulated sensor system that can withstand high shock and vibration as well as operate up to +170°C, and endure high pressure wash-downs (IP69K). The sensor is activated by a separate magnet in a choice of three options.
NRH285DR is designed for applications in extreme environments where space is limited. It also allows up to ±2mm radial offset, with a permissible gap 2-7mm between the sensor and magnet. The transmissive properties between the magnet and sensor also allow operation through non-magnetic materials.
