Photocell/Photoelectric Sensor Panasonic PM-K45-C3 K-type, bright/dark switching, 5–24 V DC

Panasonic PM-K45-C3 is a K-type photoelectric sensor designed for compact, reliable optical detection in industrial automation. The sensor supports both bright (light-on) and dark (dark-on) switching modes and operates from a DC supply voltage range of 5–24 V. It is intended for presence detection, counting, conveyor control and other applications where interruption or reflection of light is used to detect objects or motion.

Advantages

The sensor combines selectable bright and dark switching modes in a single compact device, and its wide DC supply range of 5–24 V allows compatibility with a variety of control systems. Its design is focused on dependable optical sensing for material handling and machine monitoring tasks, enabling consistent detection performance in standard industrial settings.

Suitable for

• Presence detection on production lines
• Counting parts or products
• Conveyor belt control and object position sensing
• Machine safety monitoring where optical interruption is required

Key specifications

• Sensor type: Photoelectric (photocell), K-type
• Switching modes: Bright (light-on) and Dark (dark-on) selectable
• Supply voltage: DC 5–24 V
• Application: Object detection, counting, conveyor control, machine monitoring

How to use

Install the Panasonic PM-K45-C3 in the line of sight of the target area according to mounting recommendations for K-type photoelectric sensors, ensuring secure mechanical fixation and correct alignment with reflector or through-beam counterpart if applicable. Connect the sensor to a compatible DC power supply within the 5–24 V range and wire output to the control input of a PLC, counter, relay or other control device. Select the required switching mode (bright or dark) following the manufacturer’s instructions and verify detection distance and sensitivity during initial setup. Perform functional tests by introducing and removing objects to confirm reliable switching behavior before commissioning.

Recommendations

Use stable mounting and proper alignment to minimize false triggers; protect the sensing face from heavy contamination and direct mechanical impact. Match wiring and supply to the specified DC range and use appropriate cable routing and shielding in electrically noisy environments. Verify mode selection and test the sensor in the actual operating environment to confirm performance.
