APS vs PCAP: Five great reasons to switch your sensors

By Stefano Rosato | 16 August 2024

When it comes to the world of sensor technology, we like to think that we know our stuff. And while the principles that are central to pressure sensors have been around for some time, we’re certainly seeing a new interest in the latest advancements in the field.

It makes sense, as the latest in Advanced Pressure Sensors have a number of advantages over the traditional PCAP (Projected Capacitive) technology and our customers are always keen to explore ways to make their products and projects more effective, flexible and with a reduced development time. Industrial sectors, of course, have some very specific challenges to address, so we are frequently tasked with finding solutions that will not degrade over time and perform under the most extreme conditions. So, here are the top five reasons we recommend they make the switch to APS: 

1. Creates New Material Options

PCAP technology is primarily limited to glass or acrylic materials, but the new breed of pressure sensors can be integrated into a world of interesting materials – think metal, wood, plastic, and even stones. It’s a level of flexibility that our customers love and it allows for broader application across industries, more design freedom and an enhanced user experience.

2. Greater Reliability

APS boasts an impressive lifespan and remains durable even beyond ten million uses. This is significantly higher than the typical 500,000 uses seen in mechanical and capacitive sensors. Better still, their robust anti-interference capabilities mean even greater reliability in diverse environments.

3. Superior Surface Treatment

These sensors perform superbly in the most challenging environments. They are waterproof, dustproof and oil-resistant, making them perfect for applications requiring durability and resistance in the kind of conditions where PCAP sensors may struggle. They are also ready for IPXX certification, ensuring reliability in harsh conditions.

4. Easy Assembly

The new pressure sensors eliminate the need for holes or additional holders for mounting, which, of course, simplifies the assembly process. But it also maintains the integrity of the surface material, which results in a sleek design-led finish.

5. Sensitivity

Advanced Pressure Sensors are specifically designed to detect even the slightest deformation under pressure, which means they are high on sensitivity and precision. So, when you need exact measurements and subtle touch detection, they are the clear choice over PCAP sensors, which rely on changes in capacitance through direct touch or a stylus.
