Non-contacting SRH76x series features two independent, electrically-isolated outputs and is ideal for use in the harshest on- and off-highway vehicle environments.
Curtiss-Wright’s Industrial Division announces the launch of the SRH76x to join the extensive range of Penny & Giles Hall-effect rotary sensors. The SRH76x rotary sensor is designed with non-contacting, Hall-effect technology, offering long-life, and high performance measurement with two independent and electrically-isolated outputs. The sensors are contained in a zinc-aluminum alloy body with engineered polymer bearings and fully sealed electronics. The SRH76x range has been developed to meet the requirements of heavy-duty, industrial position-sensing with a robust, mechanical design offering exceptional levels of performance; ideal for use in hostile on- and off-highway vehicle environments.
The sensor shaft assembly is mechanically isolated from the fully sealed electronics via a solid metal bulkhead. This offers the advantage of a >20 million operations shaft seal and bearing life together with best in class IP68(2M) and IP69K sealing. This innovative design results in improved sensor integrity, exceptional reliability and optimized cost of ownership.
The SRH76x range of sensors provide a choice of working angle from 20° to 360° providing optimized 12-bit resolution and full-scale output signal over the working angle for maximum output sensitivity and resolution.
The SRH76x operates directly from 12 or 24Vdc battery systems with internal circuitry providing transient protection to ISO7637 test pulse 1-5. This combined with a selectable range of voltage, current or digital PWM outputs, offers designers the optimal combination of performance, safety and cost for ease of system integration.
In addition to the data above, the SRH76x rotary position sensors also feature:
- Dual redundancy for safety-rated systems ISO11452, IEC61508
- Industry standard M12 connector interface, M6 mounting holes
- 100V/m EMC immunity
- <+/-0.4% Linearity
- <1mV rms output noise
- Operating temperature from -40°C to +85°C (SAE J1455)
- 2KG shaft load capability
- 2500g shock / impact resistance
- >20 million operations of 150° sweep
- MTTFd >150 years
