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 packaged into 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.
