Product description

The PB501/ PB511/ PB521 photoelectric beam sensors have
an infrared transmitter (Tx) and receiver (Rx). They are
designed to be "AND gated". An alarm is initiated only when
two stacked beams are simultaneously interrupted. If one
beam is interrupted (eg, by an insect or a leaf) it does not
initiate an alarm. Four beam frequency channels are available
to prevent cross talk when using multiple units.
