OGLW / ORL

The Captron OGLW and ORL series likely refer to specific types of Fork Light Barriers within their OGL series of optical sensors. Let's break down the possible differences:

OGLW - Likely indicates a Wide Beam Fork Light Barrier: Features a wider beam gap between the transmitter and receiver, allowing for the detection of larger objects or objects moving at a greater distance.

Applications:

• Detecting larger objects.
• Monitoring wider conveyor belts.
• Applications with greater object-to-sensor distances.

ORL - Likely indicates a Retroreflective Fork Light Barrier: likely utilizes a retroreflective principle. A reflector is placed opposite the transmitter, and the receiver detects the reflected light beam.

Applications:

• Space limitations prevent the use of a direct-through beam.
• Background interference is a concern.
• Reliable object detection is required in challenging environments.
