Output Voltage: 3.3V ( 3.2 ~ 3.4V ).
Power-on stabilization time: 15S(13~17S).
Blocking/Delay Time: 2S/5S(Typ. ).
ESD Characteristics: Contact Discharge/Air Discharge 2KV(Typ. ) Resistor R14 is the resistor to adjust the sensing threshold, the default value is the third gear.
R14: the larger the resistance value, the closer the sensing distance; (default 14= 93.1K ). R16 is the resistor to adjust the delay time, the default is the first gear.
R16: the larger the resistance value, the longer the delay time.
(Default R16=20K) Interface Type: (Hole spacing 2.0 / 2.54 mmx3PIN).
O: IO detection output
G: GND, power ground
V: 5V( 3.3 ~12V). Max power consumption is 15mA for normal power supply and 110uA for pulse power supply (R17 is not welded for pulse power supply and 2k is welded for normal power supply).
