Photoelectric Fork Sensor Panasonic PM-R65-P, R-Type, light-on/dark-on, 5–24 V DC

Panasonic PM-R65-P is an R-type photoelectric fork sensor designed for through-beam detection in compact automation and packaging applications. The sensor supports both light-on and dark-on modes and operates from a 5–24 V DC supply. Its single-piece fork housing enables reliable presence detection, counting, edge detection and small-part positioning where a stable, narrow sensing area is required.

Advantages

The PM-R65-P offers a compact fork form factor that simplifies installation in confined spaces and on conveyor lines. Dual-mode sensing (light-on/dark-on) increases flexibility for different target types and backgrounds without hardware changes. A wide supply voltage range (5–24 V DC) makes the sensor compatible with common control systems. The through-beam optical layout provides precise detection of small or thin objects with consistent repeatability.

Suitable for

• Counting small parts on conveyor belts
• Presence/absence control in packaging lines
• Edge detection for flat materials and labels
• Positioning and verification of thin or translucent items

Key specifications

• Sensing type: fork (through-beam) photoelectric sensor
• Sensing modes: light-on and dark-on selectable
• Supply voltage: 5–24 V DC
• Output type: switching output compatible with DC control circuits
• Mounting: fork-style housing for insertion around targets
• Application focus: precise detection of small, thin or flat objects

How to use

Install the sensor so the object to be detected passes through the fork opening and aligns with the optical axis. Connect the power supply within the specified 5–24 V DC range and wire the switching output to the control input of the machine or PLC according to the control wiring standards you use. Select light-on or dark-on mode depending on whether detection should occur when the beam is interrupted or when the beam is received. Adjust mounting position and alignment to ensure the target reliably intersects the beam for consistent switching behavior.

Recommendations

For stable long-term performance, keep the optical surfaces clean and avoid stray ambient light entering the fork. Use mechanical guides or fixtures to maintain consistent target position when detecting very small or flexible parts. Verify switching behavior after installation and periodically during operation to account for vibration or process changes.
