Barrera fotoeléctrica de horquilla Panasonic PM-L25-P, 5–24 V DC, conmutación por luz/oscuridad

Panasonic PM-L25-P is a fork-type photoelectric sensor designed for non-contact presence detection and object sensing in automation applications. Built to operate from 5 to 24 V DC, the compact fork body provides precise alignment and stable detection of small parts, edges, labels and thin materials. The sensor supports both light-operate and dark-operate modes, allowing flexible integration into systems that require either detection when the beam is interrupted or when the beam is present.

Advantages

The fork design ensures consistent optical alignment and reduces setup time compared with separate emitter/receiver pairs. Wide operating supply range (5–24 V DC) simplifies wiring and compatibility with common control systems. Support for both light- and dark-operate modes allows adaptation to different application logic without additional hardware. Compact dimensions and reliable non-contact sensing help minimize wear and maintenance in high-cycle processes.

Suitable for

• Detection of small components on assembly lines
• Edge and label sensing on web or strip materials
• Presence/absence checks in packaging machines
• High-speed part counting and positioning tasks

Key specifications

• Sensor type: fork-type photoelectric sensor
• Supply voltage: 5–24 V DC
• Operation modes: light-operate and dark-operate selectable
• Detection method: through-beam interruption inside fork
• Form factor: compact fork for precise alignment of small objects

How to use

Install the sensor so the target passes through the fork opening and interrupts the optical path or allows the beam, depending on the chosen mode. Connect power supply within the specified 5–24 V DC range and configure the output logic to match light- or dark-operate behavior. Position the sensor at a stable mounting location with secure fastening to maintain alignment, and adjust the installation to ensure consistent object transit through the sensing aperture.

Recommendations

For reliable detection, keep the fork opening free of debris and ensure the target fully passes the sensing area. Use appropriate cable routing and shielding if operating near strong electromagnetic sources. Verify mode selection and test with representative parts at production speed to confirm stable switching before full-scale deployment.
