Q50 series sensors feature compact, all-in-one design and require no separate controller. Near and far sensing window limits are set quickly using simple push-button or remote signal TEACH-method configuration. The analog output has the option of being set with a sensing distance centered within a 100 mm window. The sensor features Banner's patented digital signal processing algorithm3, which automatically distributes the 0 V DC to 10 V DC (or 4 mA to 20 mA) output signal over the width of the configured window. QD fitting rotates for wiring in any direction Figure 1.

The emitter circuitry and optics create a light source which is directed toward a target. The light source bounces off the target, scattering some of its light through another lens to the sensor's position-sensitive device (PSD) receiver element. The target's distance from the receiver determines the light's angle to the receiver element. This angle determines where the returned light will fall along the PSD receiver element. The position of the light on the PSD receiver element is processed through analog and digital electronics and analyzed by the microprocessor, which calculates the appropriate output value. The analog output provides either a current or voltage output, or a variable signal proportional to the target's position within the user-configured analog window limits. Programmed Sensing Window Figure 2. Using optical triangulation to determine sensing distance Installation Notes Some targets pose specific problems for sensing distances. Examples include those with a stepped plan facing the sensor, a boundary line, or rounded targets. For such applications see Figure 3 on p. 3 and Figure 4 on p. 3 for suggested mounting orientations.

The Q50 sensor operates in two modes: TEACH (or configuration mode) and Run mode. Note: All LED indicators momentarily turn OFF when the sensor changes state between Run mode and TEACH configuration. Configuration Instructions Push-Button Procedure 1. Press the Teach button until the Teach LED turns red (hold button in for about 2 seconds). This indicates the sensor is waiting for the first window limit. 2. Configure the first limit. a) Position the target for the first limit The Range LED should be green, indicating a valid target. b) Briefly press the Teach button. The first limit is configured. The Teach LED flashes red at 2 Hz to acknowledge receiving the first window limit. It is now waiting for the second limit. 3. Configure the second limit. a) Position the target for the second limit. The Range LED should be green, indicating a valid target. b) Press the Teach button again. The second limit is configured. The Teach LED will turn either amber or OFF as the sensor returns to RUN mode. Remote Configuration Configure the sensor remotely or disable/enable the push button using the gray wire. This is accomplished via the gray wire. Disabling the push button prevents unauthorized or accidental changes to the configuration settings. Connect the gray wire of the Q50 Gauging Sensor to +5 V DC to 30 V DC, with a remote configuration switch connected between them. Note: The impedance of the remote teach input is 15 kΩ. To configure, pulse the wire as illustrated in Figure 5 on p. 4. The duration of each button click or remote input pulse is defined as T, where T is: 0.04 s < T < 0.8 s. > 0.8 sec T Remote T each Window Limits T Teach First Window Limit T T Teach Second Window Limit T T T Push Button Lockout T T Push Button Lockout 0.04 sec < T < 0.8 sec Figure 5.

If the near limit is taught first, the slope will be positive; if the far limit is taught first the slope will be negative. Banner's patented scalable analog output automatically distributes the output signal over the width of the programmed sensing window. (Output is either 0 V to 10 V or 4 mA to 20 mA, depending on the model.)

Analog current output as a function of target position (loss of signal – 3.6 mA) Teaching Analog Limits Using a Fixed 100 mm Window For some analog applications, a sensing distance set point centered within a sensing window is required. The TEACH procedure is simple: teaching the same limit twice causes the sensor to configure a window centered on the position taught. This window is 100 mm wide (taught position ±50 mm).
