The H22A1 slotted optical switch is a gallium arsenide light emitting diode coupled to a silicon photodarlington in a plastic housing. The gap in the housing provides a means of interrupting the signal with opaque material, switching the output from an “ON” to an “OFF” state.

Technical Specification:

• Sensor Output: Phototransistor
• Sensor Mounting: Through Hole
• Gap Width: 15mm
• Aperture Width: 889mm
• Forward Current: 60mA
• Forward Current:60mA
• Forward Voltage:7V

Features:

• Opaque housing
• Low cost
• 35” apertures

Applications:

• DC motor position / velocity control
• Position and velocity servomechanisms
• Factory automation robots
• Numerically controlled machinery
• Computer printers and plotters
• Facsimilies
• Optoelectronic Switches
