Barrera de horquilla Panasonic PM-L25-C3 forma L, 5-24 V DC, conmutacion clara y oscura

The Panasonic PM-L25-C3 is an L-type photoelectric fork sensor designed for reliable object detection in automation and handling equipment. Built to operate from 5 to 24 V DC, this fork sensor supports both light-on and dark-on switching modes for flexible integration into conveyor systems, pick-and-place stations and labeling or edge-detection tasks. The fork shape enables through-beam style sensing of small parts, labels, or material edges without mechanical contact.

Advantages

This fork sensor offers a compact L-type design that simplifies mounting in limited spaces and around guides. Its dual switching modes (light-on and dark-on) allow selection of the detection behavior that best fits the application and ambient conditions. The electrical operating range of 5–24 V DC provides compatibility with common industrial power supplies and control systems. The through-beam fork configuration ensures precise detection of thin or small targets and reduces false triggers from surrounding material.

Suitable for

• Edge detection on webs, films and sheets
• Label presence and gap detection on packaging lines
• Small-part detection on conveyor belts and feeders
• Pick-and-place verification in assembly machinery

Key specifications

• Sensor type: L-shaped photoelectric fork (through-beam fork)
• Supply voltage: 5–24 V DC
• Switching modes: light-on (light-operate) and dark-on (dark-operate)
• Detection method: optical through-beam for precise edge and small object sensing
• Mounting: fork-style housing for insertion of target between emitter and receiver

How to use

Install the sensor so that the target passes cleanly through the fork opening between the emitter and receiver. Secure the fork housing to a fixed bracket or machine frame aligned with the conveyor or guide path. Wire the sensor to the control system following the manufacturer’s wiring conventions for supply and switching outputs, and select the desired switching mode (light-on or dark-on) based on whether detection should occur when the beam is received or interrupted. Adjust mechanical alignment to ensure consistent target placement through the sensing gap and test with representative parts to confirm stable switching behavior.

Recommendations

Position the fork close enough to the target path to minimize stray light and reflection effects, and keep the sensing gap free of dust and debris. Choose dark-on switching for reliable detection of opaque parts and light-on switching when detecting transparent or low-contrast targets. Verify cable connections and use appropriate shielding and cable routing to reduce electrical noise in industrial environments.
