- of an integral connector increases durability because pigtails are notoriously fragile. Wires in a pigtail can become strained, frayed, eaten by rodents or crimped.
- Is EMI/EMC resistance important for your design? Radio waves of different frequencies can interrupt electronics. Automotive-grade EMI/EMC protection provides reliability in sensor performance against radio frequencies in the environment.
- Can you utilise a standardised I/O? Using industry-standard AMP termination, 32 mm mounting pitch and universal pin-out styles may help you save time and money. Standard I/Os can greatly simplify drop-in replacement because the mounting points, profile and pin-outs are similar to those of the incumbent device.
- How flexible do the sensors for your design need to be? Determine if you are working with one power setting or if the sensor should be able to work with a variety of input voltages. It could be beneficial to use position sensors that provide a wide span of operating voltages or ranges. A variety of operating ranges can provide design engineers the resolution needed in the span of travel in many common applications.
- Is your sensor manufacturer reliable? It is important to consider whether your supplier can provide the engineering, testing, quality and customisation expertise you need for your products. Additionally, it can be beneficial if the supplier knows and understands international standards, as well as manufacturing/shipping processes and policies.
Why is the Hall-effect rotary position sensor suitable for heavy duty vehicle equipment?
Foot Pedal Position Sensing
In heavy-duty vehicle equipment and other vehicles, Hall-effect rotary-position sensors may be used to replace the mechanical cable connection between the foot pedal and the engine. A mechanical cable can stretch or rust, potentially requiring regular maintenance and recalibration. Eliminating the mechanical cable can improve the engine control system response, benefitting the vehicle’s emission, improving reliability and reducing excess weight. This type of drive-by-wire system can be both safer and less expensive than cable-connected systems.
For example, a rotary-position sensor
