small batches, or resulted in poor graphene. The proprietary technology that Paragraf
has developed is bringing the incredible capabilities of graphene out of the lab and into the commercial world. Through a highly scalable direct-deposition technique, that seamlessly integrates with semiconductor industry production workflows, the high volume fabrication of graphene-based electronic components has been made possible. This technique eliminates the need for graphene to be transferred from another substrate, mitigating the contamination and structural integrity issues that this causes. Leveraging this technique, the field-proven
Graphene Hall Effect Sensor (GHS) series now being supplied by Paragraf will present encoder manufacturers with the technology needed to revolutionise their products. It will give them the opportunity to address the demands now being set by OEMs of machine tools and other forms of industrial equipment. Featuring 2D sensor elements,
GHS sensors deliver much higher magnetic field resolutions than are possible with conventional magnetic sensor (going all the way down to sub-µTesla levels). As a result, considerably smaller changes in position can be ascertained. They are also less susceptible to the
presence of stray fields and hysteresis issues.
what this means for encoder manufacturers and oems Through designing graphene-based sensors into their designs, encoder manufacturers will gain advantages that will not only be of value to them, but can also be passed on to the OEMs they serve. These include: • By having access to more accurate sensing capabilities, the resolution levels needed will be possible using a smaller number of components. Systems will therefore be simpler to implement, reducing BoM costs whilst improving profitability without compromising accuracy levels.
FEATURE
• The insusceptibility of GHS sensors to stray fields will significantly reduce the amount of magnetic shielding needed. This will again reduce the overall expense and payload.
•. Calibration during encoder production will be much more straightforward, with less work involved – equating to lower engineering costs. After encoders have been deployed into end customers’ equipment, re-calibration will need to be carried out on a far less regular basis. This will allow production lines to keep running for longer, boosting productivity and avoiding downtime.
new possibilities The industrial sector is about to experience a step change in what can be achieved with regard to the resolutions that magnetic encoders will support. This is going to open up an array of new possibilities to encoder manufacturers – in relation to the breadth of applications that can be attended to, and tackling the costs involved in producing their devices. All this is down to the progression that has been made in graphene fabrication. The manufacturers that are quickest to adopt graphene-based magnetic sensors will be the ones that gain the biggest rewards.
