Type 2 safety light curtain CSA90-T0311DN2

multibeamthrough-beamIP65

1. **Naming Rule**
CSA series general-purpose area light curtain.
Coding Structure: `CSA + Pitch - T03 + Quantity + D + □1/2`

- CSA: Fixed series code for area light curtain
- Pitch: 10/20/30/40/50/60/70/80/90mm optical axis pitch
- T03: Fixed sensing range of 0.1~3m
- Quantity: Optical axis number
- D: Complete set (emitter + receiver)
- □: Output type, N=NPN, P=PNP
- 1/2: Cable version option
‑ Example: CSA10-T0308D N1/2, CSA20-T0304D P1/2

2. **Available Part Numbers**
Full series with 9 types of optical axis pitches: 10mm,20mm,30mm,40mm,50mm,60mm,70mm,80mm,90mm.
Optical axis quantity ranges from 2 to192; corresponding protected height:60~2500mm.
Two output versions: Switching light curtain (NPN/PNP transistor open collector output) and 485 communication light curtain.
3. **Detection Principle**
Infrared through-beam area light curtain, adopts infrared 850nm light source. Minimum detectable object: ≥Φ15mm opaque object. Features small blind zone, the same detection height supports more installation space. Custom sunlight-resistant and IP67 models are available.
4. **Sensing Range**
Sensing distance: 0.1~3m for switching output type; 0.1~3m or 0.1~10m for RS485 version.
Response time: ≤20ms (varies by optical axis quantity).
Protected height: 60~2500mm, optical axes from 2 to192.
Connection: M12 connector.
5. **Main Model Versions**
Two variants: Switching quantity light curtain / RS485 light curtain.
Power supply: DC24V (ripple(P-P) ≤10%).
Output: NPN or PNP transistor open collector output, load current 6. **Key Features**
‑ Multiple optical axis pitch options:10/20/30/40/50/60/70/80/90mm for flexible selection.
‑ Small blind zone, saving installation space. Custom anti-sunlight and IP67 models available.
‑ Protection circuit: Output short-circuit protection, reverse power connection protection.
‑ Indicator lights: For synchronous wire type, green LED lights on for both emitter and receiver under normal status. For RS485 synchronous type, green LED on for normal state; red LED lights up for alarm and flashes for failure.
‑ Enclosure: Aluminum alloy housing; filter: PMMA; end cap: ABS; IP65 protection grade.
‑ Strong environmental adaptability: Operating temperature -15~55℃, storage temperature -25~70℃ (no icing & condensation). Operating/storage humidity: 35~85%RH (non-condensing).
‑ Ambient light resistance: Max 3000W incandescent lamp, 10000lx sunlight, incident angle ≤5°.
‑ Reliability: Insulation resistance20MΩ (DC500V); Withstand voltage: AC1000V 50/60Hz for 1min; Anti-vibration & anti-shock capability.
7. **Operation Mode**
Light-on normally closed / Dark-on normally open. RS485 version supports Light-on normally closed / Dark-on normally open.
8. **Output Options**
Switching version: NPN or PNP open collector output.
RS485 version: RS485 communication output.
