Compact, SMD sensor packaging on tape and reel accommodates many OEMs’ automated pick-and-place PCB manufacturing and wave soldering processes, simplifying production, and helping to reduce production costs for the OEM. While an SMD sensor is vastly popular for high volume OEM users, other applications may require different features and packaging. That is why it is always important to work closely with the sensor provider when determining the right sensor for an application. Access to and assistance from sensor experts and application engineers is critical to making the right choices. Sensor construction consists of a planar capacitor with a second polymer layer to protect the sensor against moisture, dirt, dust, oils, common environmental chemicals, and other hazards. Additionally, the near linear voltage output provides instrumentation-quality performance.
