The H22L series are slotted switches designed for multipurpose non contact sensing. The consist of a GaAs LED and silicon LOGIC OUTPUT sensor packaged in an injection molded housing , facing each other across a 3mm gap. The output is either inverting on non inverting, with a choice of totem- pole or open collector configuration for TTL/CMOS compatibility.
