H21LTI - OPTOLOGIC OPTICAL INTERRUPTER SWITCH

General 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.

Key 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 configuration.
  • TTL/CMOS compatible output functions  2001 Fairchild Semiconductor Corporation DS300294 5/29/01 1 OF 8 www. fairchildsemi. com.
