(1) Confirm “+” and “–” polarity first. If the polarity is opposite, sensor cannot operate.
(2) Do not supply power voltage more than the specification. It will cause breakdown
on pickup.
(3) Shield wire (Silver) connect on minus side of power supply.
(4) In case of using any receiver such as logger with 1-
5V, connect 250Ω resistance
with it in parallel.
