Note: The .. in the model numbers is one of the following:
•
E =
Emitter
•
TR = Trip-Output Receiver
•
LR = Latch-Output Receiver
•
TP = Trip-Output
Emitter/Receiver
Pair
•
LP = Latch-Output
Emitter/Receiver
Pair
Pair model numbers end in 88 (for example, LS2TP30-150Q88) to indicate that both the
transmitter
and receiver
have an 8-pin connector.
