Photoelectric Fork Sensor Panasonic PM-Y65, fork-type light barrier, 5–24 V DC, bright- and dark-switching

Panasonic PM-Y65 is a fork-type photoelectric sensor designed for reliable non-contact detection in automation and positioning tasks. The U-shaped housing forms a stable light barrier that detects small parts, labels, edges and other targets passing through the slot. The sensor accepts a supply voltage range of 5–24 V DC and supports both bright-switching (light-operate) and dark-switching (dark-operate) modes for flexible integration into control circuits.

Advantages

The fork design provides consistent alignment of emitter and receiver for repeatable detection without mechanical contact. Wide supply voltage compatibility (5–24 V DC) simplifies wiring and makes the sensor suitable for a variety of industrial control systems. The ability to select bright- or dark-switching operation allows adaptation to differing signaling logic and ambient light conditions. Compact U-shaped housing supports installation on conveyor lines, feeders and assembly stations where space is limited.

Suitable for

• Detection of small components and parts on conveyors
• Label and edge detection in packaging and printing
• Positioning and presence sensing in assembly equipment
• Counting and sorting applications with narrow targets

Key specifications

• Sensor type: fork-type photoelectric sensor (U-shaped light barrier)
• Supply voltage: 5–24 V DC
• Output behavior: selectable bright-switching (light-operate) and dark-switching (dark-operate)
• Sensing method: through-beam detection within the fork slot
• Mounting: slot/fork mounting for inline detection of passing objects

How to use

Mount the sensor so the slot is aligned with the path of the object to be detected. Connect the power supply within the rated 5–24 V DC range and wire the output according to the required control logic for bright- or dark-switching operation. Adjust the installation position to ensure the target interrupts or restores the light beam reliably as it passes through the fork. Verify correct operation by running representative parts through the sensor slot and observe the output response in the control circuit.

Recommendations

Install the sensor in a location with minimal contamination inside the fork opening; periodic cleaning of the emitter and receiver faces prevents misdetection. Use secure mechanical mounting and strain relief for wiring. When used in environments with ambient light or reflections, test both switching modes to select the most reliable output behavior for your application.
