Photo Interruptor Ricoh AW020249 flat pitch 2 mm M4 mounting

Ricoh AW020249 photo interruptor with a flat 2 mm pitch and M4 mounting interface is a compact optical sensor designed to detect object presence or motion by interrupting a light beam. Its flat-pitch form factor enables close-spacing on PCBs and compact mechanical assemblies, making it suitable for position sensing, paper-feed detection and similar precision applications in printers, copiers and small electromechanical devices.

Advantages

The flat 2 mm pitch reduces required board area and supports tight component placement without compromising sensing distance. The M4-compatible mounting provides stable mechanical fixation in assemblies. The optical interrupter design offers non-contact detection for wear-free operation and consistent switching performance. Its compact envelope and straightforward interface simplify integration into constrained spaces and established paper-path or mechanical-position systems.

Suitable for

• Position sensing in printers and copiers
• Paper-feed and jam detection mechanisms
• Small electromechanical devices with limited PCB space
• Applications requiring non-contact object detection

Key specifications

• Flat pitch: 2 mm for close component placement
• Mounting interface: M4-compatible mechanical fixation
• Sensing method: optical beam interruption
• Form factor: compact, suitable for constrained assemblies
• Typical use: position and motion detection in electromechanical systems

How to use

Install the photo interruptor so the emitter and detector are aligned with the expected object path; use the M4-compatible mounting point to secure the device and adjust position to achieve the required sensing window. Route PCB traces and connectors following the device datasheet recommendations for signal and power connections, and verify alignment by observing switching behavior with representative targets. Ensure the device is mounted to minimize vibration and mechanical misalignment that could affect the optical beam.

Usage recommendations

For reliable operation, keep the optical path free of dust and debris, confirm alignment during assembly and perform functional tests under actual operating conditions. When integrating into paper-feed systems, allow for margin in sensing position to accommodate media variations; consider enclosure or shielding if ambient light could interfere with detection.
