Electronic device for sensitive handle MS 333
 


The circuit MS 33 is sensitive to the capacitance variations and has the purpose to detect the presence of people when the contact between the handle (electrode) and the human body takes place. The MS 33 switches a relay. The main characteristic of the MS 33 is the faculty of holding under control the capacitance drift.

supply voltage:  +12Vcc DC (max 25 mA)  
minimum working voltage: +9Vcc
