H21LTB - OPTOLOGIC OPTICAL INTERRUPTER SWITCH
The H21L series are slotted optical switches designed for multipurpose non contact sensing.
They consist of a GaAs LED and a silicon OPTOLOGIC®.
sensor packaged in an injection molded housing and facing each other across a .124” (3.15 mm) gap.
The output is either inverting or non-inverting, with a
