ES92B4 Photoelectric switch sensor

Description: The BY-ES92B4 (Slot Optical Switch) combines a gallium arsenide infrared emitting diode with a silicon phototransistor in a robust plastic housing. This packaging design optimizes mechanical resolution, coupling efficiency, and effectively shields against ambient light. The integrated slot allows for interruption of the signal by opaque materials such as printers, scanners, copiers, or similar devices, toggling the output from “ON” to “OFF” states.

Key Features:

• Fast response time
• High sensitivity
• Cut-off visible wavelength λp = 940nm
• Lead (Pb) free
• RoHS compliant
• EU REACH compliant

Applications:

• Mouse copiers
• Scanner switches
• Floppy disk drivers
• Non-contact switching applications
