Photoelectric Fork Sensor Panasonic PM-T45-P-C3 T-type, 5–24 V DC, light-on/dark-on

Panasonic PM-T45-P-C3 is a T-type photoelectric fork sensor engineered for precise object detection inside a fork profile. Designed for industrial automation, the sensor accepts a 5–24 V DC supply and provides selectable light-on or dark-on switching modes to suit different sensing tasks. Its compact T-shaped housing allows reliable presence, edge or label detection of small parts and supports position control in assembly lines where space and repeatability are important.

Advantages

The fork design ensures stable alignment and reliable detection of thin or small objects without requiring additional optics. Wide supply voltage range (5–24 V DC) makes it compatible with typical control systems. Switchable light-on/dark-on operation increases flexibility for varied applications and improves immunity to ambient changes. The compact form factor facilitates installation in tight spaces and on automated equipment.

Suitable for

• Presence detection of small components on conveyors
• Edge or leading/trailing detection of labels and tapes
• Position control in pick-and-place and assembly stations
• Object counting and quality control where compact sensors are required

Key specifications

• Sensor type: T-type fork photoelectric sensor
• Operating voltage: 5–24 V DC
• Switching modes: selectable light-on and dark-on
• Detection method: through-beam fork sensing suitable for thin or small objects
• Housing: compact T-profile for installation in confined spaces

How to use

Mount the sensor so that the object passes through the fork gap perpendicular to the emitter-receiver axis. Connect the supply within the specified 5–24 V DC range and set the output polarity to light-on or dark-on according to the application. Adjust the sensor alignment and secure the housing to prevent movement; verify switching behavior using test parts or a controlled run. Integrate the sensor output to your control system for counting, stopping, or position verification functions.

Recommendations

For reliable detection, keep the fork gap free of dust and debris and ensure stable mechanical alignment. When sensing very thin or reflective materials, test both switching modes and adjust sensor mounting to find the best orientation. Use appropriate mounting brackets or protective covers if the environment exposes the sensor to mechanical impact or contaminants.
