⚠️ Distinzione importante
- CML720i = Measuring light curtain, no safety certification. Cannot be used for personnel safety protection; Safety light curtain series: MLC.
- Complete system = Transmitter (T) + Ricevitore (R) paired. Transmitter alone cannot work.
- Supporta 3 scanning modes: Parallel beam / Slanted beam / Cross beam, configurable via receiver.
HS Code Reference
90314990 (Optical measuring sensor / photoelectric detection device)
Guida alla risoluzione dei problemi
- Power ON, transmitter green LED steady ON: Normale; Lampeggiante: Synchronization error (transmitter-receiver out of sync, guasto al cablaggio)
- No signal: Check parallel installation of transmitter & ricevitore, operating distance ≤3.5m, no strong direct light on lens
- Inaccurate measurement: Clean lens, verify beam mode setting, eliminate reflection interference

- Transmitter only carries power & sync lines; All measurement output and bus communication are integrated in receiver
- Identical mechanical dimensions: W29 × D35.4 × L315 mm, supplied with 2 BT-NC mounting sliders
Cable Information
Sync cable between transmitter & ricevitore: M12 5-core, connects Transmitter ↔ Receiver
Receiver connects to PLC via separate bus / analog cable

Pin1/3: 24V Power Supply
Pin6/7: Sync signal to transmitter
Pin2/Pin5: Digital IO (Colpa / Insegnare)
⚠️ Nota: Analog output and RS485 sync share Pin7, internal auto switching. Wiring remains unchanged; voltage/current mode configured via Leuze software.
📌 General Wiring Guidelines
- Power supply range DC18~30V, Consigliato 24 V CC; Isolated power supply required, shield single-point grounding.
- Sync cable (Transmitter ↔ Receiver) max length 20m; Bus cable max 40m, shielded cable mandatory.
- Sequenza di cablaggio: Connect shield ground first → Wire all signals → Power ON; Power OFF before disassembly.
- IO1 default as Teach input, short to GND to trigger teach routine for zero calibration.
- Separate signal cables from power cables to avoid interference from frequency converters.
