C&K Components has upgraded its KMT0 Series of ultra-miniature tactile switches to provide IP68-rated sealing. The industry’s only ultra-miniature tactile switch with an IP68-rated sealing, the KMT0 Series is completely sealed and stays fully functional under water for a minimum of 5 hours at a depth of 2 meters. In addition, the KMT0 Series is fully resistant to the most stringent conformal polymer coatings and features a lifespan of more than 300,000 electrical and mechanical cycles.
The footprint of only 3.0mm x 2.6mm with a height of 0.63mm or 0.65mm, the IP sealing and the extended life cycle make the RoHS-compliant and halogen-free KMT0 switches a viable solution for handheld and portable electronic device applications. They are integrated i.e. in consumer electronics and medical devices, such as hearing aids, mobile phones, MP3 accessories and Bluetooth headsets. All devices of the KTM0 Series feature a maximum power rating of 0.5VA and a minimum/maximum voltage of 20mV – 32Vdc with a minimum/maximum current rating of 1mA – 50mA. The operating temperature ranges from -40°C to +85°C.
