Contact protection countermeasure for reed switch type sensor switch
z
In the case of connecting inductive load (electromagnetic relay, etc.)
z
In the case of capacitive surge generated
(when lead wire length exceeds 10 m [32.8 ft])
For stable use of reed switch type sensor switches, take the contact protection countermeasure below.
Inductive load
Surge absorption element
In the case of DC: Diode or CR, etc.
In the case of AC: CR, etc.
Diode: More than the circuit current for the forward current,
and dielectric strength of more than 10 times
the circuit voltage for the reverse direction.
C: 0.01 to 0.1
