H21L Series OPTOLOGIC Optical Interrupter Switch
Features
■ Low cost ■ 0.035" apertures ■ Black plastic opaque housing ■ Mounting tabs on housing ■ Choice of inverter or buffer output functions ■ Choice of open-collector or totem-pole output
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 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.
