Note
Note
1.
Follow wire color code for proper connection. Since there is no
overcurrent protection, improper wiring will break the sensor switch.
2.
For inductive load such as electromagnetic relay, etc., it is
recommended to use surge protective diode.
3.
Since the circuit voltage drops in proportion to the number of sensor
switches, avoid using AND (serial) connection.
4.
When using OR (parallel) connection, direct connection of sensor
switch outputs (black wires, for example) is possible. But, the
leakage current increases proportionally by the number of sensor
switches. Therefore, be cautious against load return failure.
5.
Avoid use in places where external magnetic field is strong, or near
large current such as power lines, as the sensor switch is magnetic
induction type. And, magnetic material should not be used in the
mounting portion. This may cause erratic operations.
6.
Do not apply excessive force by pulling the lead wire forcibly, or
bending it excessively.
7.
Avoid use in environment where it may be exposed to chemically
active agents or gasses, etc.
8.
For use in atmosphere where it may be exposed to water or oil,
consult your nearest KOGANEI sales office.
