1 Measuring wheel
2 Spring-loaded mounting arm
• Measuring wheel system mounted under the conveyor belt.
• Large spring travel and pivot range of the spring arm compensates for unevenness
on measurement surface.
• Measurement of linear movements.
• Detection of position and speed directly on the running surface of the conveyor belt
using a precision measuring wheel.
3.2.3 Photoelectric retro-reflective sensor trigger (optional)

Legend
1 Photoelectric retro-reflective sensor (e.g., RAY26)
2 Reflector
• The light band emitted by the object detection photoelectric sensor is reflected back
by a reflector.
• Sender and receiver are arranged parallel to one another in the housing.
• Mounted in front of the measuring field.
• Supplies the trigger signal in systems with triggered measurement.
• The trigger signal activates the sensors and opens the internal reading gate.
• The photoelectric retro-reflective sensor trigger is available as an option.
