Photocell Light Barrier Panasonic PM-T45-P T-type, bright/dark switching, 5–24 V DC, 1 pc

Panasonic PM-T45-P is a T-type photocell light barrier engineered for reliable optical detection in industrial and automation environments. The sensor detects objects and presence using a light beam and supports selectable bright-on and dark-on switching modes. Designed to operate from 5 to 24 V DC, this single-unit photocell is compact and suitable for inline mounting where straightforward object sensing or simple counting is required.

Advantages

The T-type design enables easier alignment and installation in tight spaces while the selectable bright/dark switching provides flexible integration with different control systems. Wide supply voltage compatibility ensures operation with a variety of DC power sources. The device’s single-output format simplifies wiring and replacement in conveyor monitoring, door control, and basic automation circuits.

Suitable for

• Object detection on conveyors and production lines
• Presence sensing for automated doors and gates
• Basic counting and position sensing tasks
• Integration into machine control and safety interlocks (non-safety-rated)

Key specifications

• Operating voltage range: 5–24 V DC
• Switching modes: bright-on (light operates output) and dark-on (absence of light operates output)
• Form factor: T-type photocell light barrier for compact mounting
• Output: single switching output suitable for discrete control inputs

How to use

Mount the photocell so the sensing axis aligns with the target area or reflector according to the T-type form factor. Connect the device to a compatible DC supply within the 5–24 V DC range and wire the single switching output to the control input of a PLC, relay, or other switching device. Select bright-on or dark-on mode depending on whether the application requires output activation when the beam is present or interrupted. Verify alignment and sensitivity on installation, then test operation under representative conditions to ensure reliable detection.

Recommendations

Ensure the photocell and its target path are kept free from dust and obstructions to maintain consistent optical performance. Use appropriate mounting brackets or fixtures to prevent vibration-induced misalignment. Match switching mode to your control logic and confirm voltage compatibility before connecting.
