WORLD-BEAM QS18LD Laser Diffuse Series Sensors Datasheet Visible Class 1 laser for diffuse sensing Narrow effective beam provides small-object detection and precise position control Crosstalk rejection algorithm protects against optical disturbance from adjacent sensors Excellent optical performance throughout sensing range, even close up 10 to 30 V dc operation, with complementary (SPDT) NPN or PNP outputs, depending on model Bright LED operating status indicators are visible from 360 Compact, rugged sealed housing, protected circuitry Mounting versatility popular 18 mm threaded barrel or side-mount Choose 2 m (6.5 ft) or 9 m (30 ft) cable or one of four QD options Models Sensing Range Spot Size at Focus Cable Output QS18VN6LD 650 nm Visible Red NPN Approximately 1 mm at 300 mm 4-wire, 2 m (6.5 ft) integral Class 1 Laser 300 mm (0.039 in at 12 in) cable QS18VP6LD PNP (12 in) The standard 2 m (6.5 ft) cable models are listed. To order the 9 m (30 ft) cable models, add the suffix W/30 to the model number (e.g., QS18VN6LD W/30). A model with a QD connector requires a mating cordset. To order the QD models: For 4-pin integral Euro-style QD, add suffix Q8 (e.g., QS18VN6LDQ8). For 4-pin integral Pico-style QD, add suffix Q7 (e.g., QS18VN6LDQ7). For 4-pin Euro-style 150 mm (6 inch) pigtail QD, add suffix Q5 (e.g., QS18VN6LDQ5). For 4-pin Pico-style 150 mm (6 inch) pigtail QD, add suffix Q (e.g., QS18VN6LDQ). WARNING: Not To Be Used for Personnel Protection Never use this device as a sensing device for personnel protection. Doing so could lead to serious injury or death. This device does not include the self-checking redundant circuitry necessary to allow its use in personnel safety applications. A sensor failure or malfunction can cause either an energized or de-energized sensor output condition.

D 118899 WORLD-BEAM QS18LD Laser Diffuse Series Sensors Description of Laser Classes Class 1 Lasers Class 1 lasers are lasers that are safe under reasonably foreseeable conditions of operation, including the use of optical instruments for intrabeam viewing. Reference IEC 60825-1:2001, Section 8.2. Class 1 Laser Characteristics: See Specifications. CAUTION: Do Not Disassemble for Repair This device contains no user-serviceable components. Do not attempt to disassemble for repair. Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. A defective unit must be returned to the manufacturer. For Safe Laser Use (Class 1 or Class 2): Do not stare at the laser. Do not point the laser at a persons eye. Mount open laser beam paths either above or below eye level, where practical. Terminate the beam emitted by the laser product at the end of its useful path.
