Photoelectric Fork Sensor Panasonic PM-K25-C3 K-type, bright/dark switching, 5–24 V DC

Panasonic PM-K25-C3 is a K-type photoelectric fork sensor designed for reliable non-contact object detection in industrial automation. Housed in a fork-style body, this sensor detects interruptions or presence of objects passing through its sensing gap. It supports both bright-on and dark-on switching modes and accepts a wide supply range of 5–24 V DC, making it suitable for integration into conveyor systems, pick-and-place stations, and positioning tasks.

Advantages

The fork design ensures precise alignment and repeatable detection of small or narrow targets without mechanical contact. Dual switching modes (bright/dark) allow flexible configuration to suit different object colors and surface finishes. The broad operating voltage range provides compatibility with various machine control systems and reduces the need for additional power conversion. Compact construction simplifies installation in space-constrained locations.

Suitable for

• Conveyor object counting and presence detection
• Position sensing for pick-and-place or robotic end-effectors
• Detecting flat, thin, or transparent parts that pass through a fork
• Integration into machine vision or quality control trigger systems

Key specifications

• Sensing type: fork-style photoelectric sensor (through-beam configuration)
• Switching modes: light-on (bright) and dark-on (dark) selectable
• Supply voltage: 5–24 V DC
• Output type: discrete switching output suitable for PLC or controller inputs
• Mounting: fork housing for object passage through sensing gap
• Detection method: non-contact optical interruption

How to use

Mount the sensor so the object to be detected reliably passes through the sensing gap. Select the appropriate switching mode (bright or dark) according to the object's contrast and surface properties, and connect the sensor to the control system using the specified DC supply range. Adjust alignment to center the target within the fork for consistent detection. Verify switching behavior with representative parts and adjust wiring and mounting as needed to prevent false triggers from ambient light or nearby reflective surfaces.
