SF2

The SF2 from Sensirion is a filter cap for use with SHT2x humidity and temperature sensor. This filter cap protects SHT2x sensors against dust, water immersion as well as against contamination by particles. The cavity inside is made such that the volume between membrane and sensor is kept minimal and hence the impact on response time for humidity measurements is reduced to a minimum. The filter cap SF2 is available in black colour with a white filter membrane and made of a single piece of Polybutylene Terephthalate (PBT) with a filter membrane welded on it. SF2 filter cap is designed to be mounted after soldering by clipping the four pins into openings in the PCB. Together with the sensor it provides a compact entity which may serve as an adaptor to the device housing. Adding adhesive for seal to PCB and using an O-ring, it serves for a waterproof mounting solution.
