Barreira ótica de garfo fotoeletrica Panasonic PM-L45-P-C3 tipo L, 5–24 V DC, comutação clara/escura

Panasonic PM-L45-P-C3 is an L-type photoelectric fork sensor designed for precise non-contact detection in automation and assembly environments. The compact fork profile allows the sensing beam to pass between two prongs, enabling detection of small parts, labels, edges or gaps on conveyor lines. The sensor accepts a wide DC supply range and supports both light-on and dark-on switching, offering flexible integration into existing control systems.

Advantages

The fork design provides stable, repeatable detection of thin or irregular objects without mechanical contact. Broad supply voltage compatibility ensures compatibility with PLCs and control equipment powered from 5 to 24 V DC. Selectable light/dark switching increases installation flexibility and simplifies wiring logic. The rugged housing and compact footprint make it suitable for confined machine spaces and straightforward mounting in production cells.

Suitable for

• Detection of small parts and components on conveyors
• Label presence and edge detection in packaging lines
• Part positioning and counting in assembly machines
• Web edge or gap detection in material handling

Key specifications

• Sensor type: L-type fork photoelectric sensor
• Supply voltage range: 5–24 V DC
• Switching modes: light-on and dark-on selectable
• Output type: discrete switching output suitable for digital inputs
• Detection method: through-beam/opposed fork arrangement
• Mounting: compact fork form factor for panel or bracket mounting
• Construction: industrial housing designed for production environments

How to use

Install the fork so the object to be detected passes between the prongs and interrupts or reflects the sensing beam according to the chosen mode. Connect the sensor to a DC supply within the specified 5–24 V range and wire the output to the control input or PLC following the manufacturer’s wiring conventions. Select light-on or dark-on switching based on whether detection should occur when the beam is present or interrupted. Adjust sensor alignment and secure mounting to ensure consistent detection performance during operation.

Recommendations

For reliable long-term operation, verify alignment after initial installation and after any mechanical changes to the line. Use the light/dark switching option to match the logic of your controller and minimize wiring changes. Protect the sensor from excessive dirt or direct impact and follow periodic cleaning to maintain consistent detection of small or low-contrast targets.
