⚠️ Distinction importante

1. CML720i = Measuring light curtain, no safety certification. Cannot be used for personnel safety protection; Safety light curtain series: MLC.
2. Complete system = Transmitter (T) + Récepteur (R.) paired. Transmitter alone cannot work.
3. Prise en charge 3 scanning modes: Parallel beam / Slanted beam / Cross beam, configurable via receiver.

HS Code Reference

90314990 (Optical measuring sensor / photoelectric detection device)

Guide de dépannage

1. Power ON, transmitter green LED steady ON: Normale; Clignotant: Synchronization error (transmitter-receiver out of sync, défaut de câblage)
2. Aucun signal: Check parallel installation of transmitter & receiver, operating distance ≤3.5m, no strong direct light on lens
3. Inaccurate measurement: Clean lens, verify beam mode setting, eliminate reflection interference

✅ Matching Receiver for CML720i-T05-240.A-M12 (Item No.50119370)

Model rule: CML720i-R05-240.A/xx-M12

R=Receiver; 05=5mm beam pitch; 240mm measuring height; A=Axial M12 straight connector; /xx = Interface suffix

Notes de sélection

1. Transmitter and receiver must be fully matched: 5mm beam pitch, 240mm measuring height, A-type axial M12 connector consistent with transmitter. Only receiver adds interface suffix /xx
2. Transmitter only carries power & sync lines; All measurement output and bus communication are integrated in receiver
3. Identical mechanical dimensions: W29 × D35.4 × L315 mm, supplied with 2 BT-NC mounting sliders

Cable Information

Sync cable between transmitter & receiver: M12 5-core, connects Transmitter ↔ Receiver

Receiver connects to PLC via separate bus / analog cable

Full Wiring for Slogan CML720i (4 Interface Versions)

General architecture: Receiver X1 (8-pin M12 A-coded) main port: Alimentation + IO + sync line to transmitter; Transmitter X3 fixed as 5-pin M12 A-coded.

Transmitter Model: CML720i-T05-240.A-M12 (X3: 5-pin M12)

Receiver X1【8-pin M12 A-coded】(Pin definition identical for all versions!)

✅ Receiver X1 (8-pin M12 A-coded, common for all variants)

✅ Transmitter X3 (5-pin M12 A-coded, fixed definition)

👉 Receiver X1 Pin1,Pin3,Pin6,Pin7 → Connect to Transmitter X3 Pin2,Pin3,Pin4,Pin5. Use Leuze Y-type sync cable, max length 20m.

1️⃣ CML720i-R05-240.A/PN-M12｜Profinet Version

Receiver equipped with 3 M12 connectors:

X1: 8-épingle (Pouvoir + Sync + IO, see table above)

X2: BUS IN (4-pin M12 D-coded)

X3: BUS OUT (4-pin M12 D-coded)

Profinet D-coded M12 (4-épingle):

Wiring Architecture:

DC24V supplied to receiver X1; Sync cable from X1 to transmitter; Profinet bus connects PLC/switch to X2, X3 daisy-chains next PN device; Enable terminator resistor on last station.

Supports PLC reading: Blocked beam number, height value, diagnostic status.

2️⃣ CML720i-R05-240.A/CN-M12｜CANopen Version

Récepteur: X1 (8-épingle, Pouvoir + Sync) + X2 (5-pin M12 A-coded CAN bus)

CAN bus X2 (5-pin M12 A-coded)

Câblage: X1 power & sync to transmitter; CAN H/CAN L connect to CAN bus; 120Ω terminator resistor required at both ends of bus.

3️⃣ CML720i-R05-240.A/L-M12｜IO-Link Version

Receiver only has X1 (8-pin M12 A-coded), no extra bus port. IO-Link multiplexes Pin4 (C/Q) of X1.

Broche1: 24V+

Broche3: 0V

Broche4: C/Q IO-Link communication → Directly connect to PLC IO-Link master port

Pin2/Pin5: Digital IO (Enseigner, fault output)

Pin6/7: Sync to transmitter

IO-Link master reads measured height and beam data directly, no extra bus cable required.

4️⃣ CML720i-R05-240.A/CV-M12｜Analog Version (Tension / Actuel)

Receiver also only has X1 (8-pin M12 A-coded), analog output on X1 Pin7.

Broche7: Analog OUT Analog Output

Parameter switchable: 0~10V or 4~20mA

Full scale corresponds to measuring height 0~240mm

Pin1/3: 24V Alimentation

Pin6/7: Sync signal to transmitter

Pin2/Pin5: Digital IO (Faute / Enseigner)

⚠️ Remarque: Analog output and RS485 sync share Pin7, internal auto switching. Wiring remains unchanged; voltage/current mode configured via Leuze software.

📌 General Wiring Guidelines

1. Power supply range DC18~30V, DC24V recommandé; Isolated power supply required, shield single-point grounding.
2. Sync cable (Transmitter ↔ Receiver) max length 20m; Bus cable max 40m, shielded cable mandatory.
3. Séquence de câblage: Connect shield ground first → Wire all signals → Power ON; Power OFF before disassembly.
4. IO1 default as Teach input, short to GND to trigger teach routine for zero calibration.
5. Separate signal cables from power cables to avoid interference from frequency converters.
