Application selection
Conveyor passage detection, Carton presence monitoring, Packaging-line object detection. Suitability must be confirmed using the actual target and machine conditions.
- Select reflector size together with working distance; the 6.5 m typical limit is not a guaranteed range.
- Verify the exact 200 mm cable + M8 snap-in, 4-pin male connection and retention style.
- Test the polarized optical system with the actual target and background.
- This sensor record does not imply an included reflector.
Installation and commissioning
Qualified personnel should install and wire the sensor with the machine in a safe, de-energized condition. Verify the exact label, supply voltage, connector pin assignment and PLC input before energizing. Test both target-present and target-absent states at the required production speed.
Maintenance and ordering
Inspect mounting, connector condition and the sensing surface regularly. Clean using an appropriate non-damaging method and repeat the functional test. This device is not a personnel-protection safety sensor. Specify the exact model and manufacturer part number when ordering; price, stock, lead time and included accessories require a separate quotation.
