Description
The H21L series are slotted optical switches designed
for multipurpose non contact sensing. They consist of a
GaAs LED and a silicon OPTOLOGIC^® sensor pack-
aged 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 choice of totem-pole or
open-collector configuration for TTL/CMOS compatibility.
