QS18LD Laser Diffuse Series Sensor 

## Features 

   - Visible Class 1 laser 

   - • 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 V DC 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 quick-disconnect (QD) options 

- WARNING: • Do not use this device for personnel protection • Using this device for personnel protection could result in serious injury or death. • This device does not include the self-checking redundant circuitry necessary to allow its use in personnel safety applications. A device failure or malfunction can cause either an energized (on) or de-energized (off) output condition.

Integral 2 m (6.5 ft) unterminated cable models are listed.  To order the 9 m (30 ft) PVC cable model, add the suffix "W/30" to the cabled model number. For example, QS18VN6LD W/30. Models with a quick disconnect require a mating cordset. To order the QD models: 

- To order the 4-pin M12 integral quick disconnect model, add the suffix "Q8" to the model number. For example, QS18VN6LDQ8. 

- • To order the 4-pin M8 integral quick disconnect model, add the suffix "Q7" to the model number. For example, QS18VN6LDQ7 

- To order the 150 mm (6 in) PVC cable model with a 4-pin M12 quick disconnect, add the suffix "Q5" to the model number. For example, QS18VN6LDQ5. 

- To order the 150 mm (6 in) PVC cable model with a 4-pin M8 quick disconnect, add the suffix "Q" to the model number. For example, QS18VN6LDQ.

Cabled wiring diagrams are shown. Quick disconnect wiring diagrams are functionally identical. 

In dark operate (DO) mode, the output is ON when the target returns less light to the sensor than the configured target and OFF when the sensor detects more light than the configured/taught target. 

In light operate (LO) mode, the output is ON when the target returns the same or more light to the sensor and OFF when the sensor detects less light than the configured/taught target.

QS18LD Laser Diffuse Series Sensor 

## Product Support and Maintenance 

## Clean Sensor with Compressed Air Then Isopropyl Alcohol 

Handle the sensor with care during installation and operation. Sensor windows soiled by fingerprints, dust, water, oil, etc. create stray light that may degrade the peak performance of the sensor. 

Blow dust from the sensor using filtered, compressed air. If the sensor is still dirty, gently wipe the sensor with a dry optical cloth. If the dry optical cloth does not remove all residue, use 70% isopropyl alcohol on a clean optical cloth, then dry with a clean dry optical cloth and blow with filtered, compressed air. Do not use any other chemicals for cleaning. 

## Repairs 

Contact Banner Engineering for troubleshooting of this device. Do not attempt any repairs to this Banner device; it contains no fieldreplaceable parts or components. If the device, device part, or device component is determined to be defective by a Banner Applications Engineer, they will advise you of Banner's RMA (Return Merchandise Authorization) procedure.
