The QS18 Adjustable Convergent Diffuse Sensor is a full-featured sensor in a miniature package. It provides control of the location of the peak excess gain, enabling economical detection of targets and stable rejection of background objects. Models are available with a visible red LED sensing beam. This adjustable convergent diffuse sensor is able to detect objects of relatively low reflectivity, while ignoring other objects in the background (beyond the cutoff point). The convergent point and peak excess gain location distance is mechanically adjustable, using the 5-turn adjustment screw on the sensor top. Backgrounds and background objects must always be placed beyond the maximum detection distance. 1. Green: Power Indicator 2. Amber: Light Sensed Indicator (Flashes for Low Gain Conditions) 3.

The adjustable convergent diffuse sensing mode is a hybrid concept that combines: - Intensity-based diffuse sensing - Convergent optics, which provide a concentrated light intensity signal at a user-set distance - Mechanically adjustable receiver lens, which allows the user to set up a reliable detection in many cost-sensitive applications This sensing mode provides a cost-effective sensor solution in some applications where a full background suppression sensor is too costly. The sensor uses a single photo detector, which receives light when the combination of lens position and target distance fall within the sensing range of the sensor. If the amplitude of the received light exceeds the detection page 4 of 13 © Banner Engineering Corp. All rights reserved. www.bannerengineering.com 18-Aug-25 QS18CV20 Mechanically Adjustable Convergent Diffuse Sensors Features threshold, the output turns ON. Targets beyond the maximum sensing distance, or targets with extremely low reflectivity result in the output remaining OFF. At the convergent optical distance of 20 mm nominally, the peak excess gain exceeds 100 times the detection threshold, so very dark targets can be reliably detected. The peak excess gain location can be moved between approximately 10 mm to 30 mm by adjusting the lens position with the Lens Adjuster. Due to the finite size of the photodetector, and the ability to move the receiver lens, the excess gain off a 90% white card target can be reduced to < 1 at convenient distances of 50 mm to 150 mm allowing the sensor to ignore background objects. ## Specifications Supply Voltage 10 V DC to 30 V DC (10% maximum ripple) at less than 25 mA, exclusive of load Sensing Beam Visible red LED, 633 nm Supply Protection Circuitry Protected against reverse polarity and transient voltages Output Configuration Current sourcing (PNP) or current sinking (NPN), depending on model.

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. In diffuse sensing modes, light operate is active when the target is present and dark operate is active when the target is absent. © Banner Engineering Corp.

When an object approaches from the side, the most reliable sensing usually occurs when the line of approach is parallel to the sensing axis. 1. Check the application parameters, such as target reflectivity and sensor-to-target distance, evaluate the background conditions, and compare them with the excess gain graph in "Figure: Excess Gain at Limits of Lens Adjuster Positions" on page 7. 2. Turn the lens adjuster fully counterclockwise. - This maximizes peak excess gain, minimizes hysteresis, and minimizes the influence of the background beyond 30 mm. 3. Present the target at the desired sensing range, and verify stable detection of the target (amber LED is on). 4. If the amber LED is off, turn the lens adjuster clockwise to increase the detection range until the target is detected (amber LED is on). 5. Remove the target, and verify that the background is not detected (amber LED is off). 6. If the background is detected (the amber LED is on or flashes), turn the lens adjuster counter-clockwise until the amber LED is off when no target is present. 7. Present the target at the desired sensing range, and verify that the amber LED turns on. 8. If the amber LED remains off, turn the lens adjuster clockwise to increase the detection range. 9. Remove the target. - If the amber LED turns off, the sensor is ready for use in the application. - If the amber LED remains on or flashes, the influence from the background is too strong. Evaluate the use of an adjustable field background suppression sensor instead of an adjustable diffuse convergent sensor. ## Sensing Reliability For the highest sensitivity, position the target at or near the distance of maximum excess gain. See "Figure: Excess Gain at Limits of Lens Adjuster Positions" on page 7. The maximum excess gain for the sensor is between 10 mm and 30 mm, depending on the lens adjuster setting. Sensing at or near this distance makes the maximum use of the sensor’s available sensing power. The background must be placed beyond the maximum sensing distance. Note that the reflectivity of the background surface also may affect the maximum sensing distance. © Banner Engineering Corp.
