FAQ No. FAQ02655

Primary Contents


Will a Photomicrosensor be damaged if the power supply is connected backwards or the output is short-circuited?


Yes, there is a possibility of malfunction from connecting the power supply backwards or shorting the output because the Photomicrosensor has no built-in reverse polarity protection circuit for the power supply or short-circuit protection circuit for the output. Care must be taken to avoid connection mistakes.
