Q45U Ultrasonic Sensors with Analog Outputs (Short Range) Piezoelectric analog proximity mode sensors with push-button or remote programming of sensing window limits Ultrasonic proximity detection from 100 to 1400 mm (4 to 55 inches) Push-button TEACH-mode programming of sensing window limits Digital filtering for exceptional immunity to electrical and acoustic noise Selectable 0 to 10V dc voltage sourcing or 4 to 20 mA current sourcing analog outputs Selectable output slope: positive or negative with increasing target distance Wide operating temperature range of 25 to +70 C all models include temperature com- pensation Rugged design for use in demanding sensing environments rated IEC IP67, NEMA 6P Choose models with integral 2 m (6.5 ft) or 9 m (30 ft) cable, or with Mini-style or Euro-style quick-disconnect fitting Input for remote TEACH-mode programming of window limits Temperature Models Cable Supply Voltage Output Type Response Time Compensation Q45ULIU64ACR 2 m (6.5 ft) Adjustable from 40 Selectable 010V dc or 4 Q45ULIU64ACRQ Yes 5-Pin Mini-style QD 1524V dc milliseconds to 1.28 20 mA sourcing seconds Q45ULIU64ACRQ6 5-Pin Euro-style QD Standard 2 m (6.5 ft) cable models are listed. To order the 9 m (30 ft) cable model, add suffixW/30 to the cabled model number. For example, Q45ULIU64ACR W/30. Models with a QD connector require a mating cable. 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. Temperature Compensation All models listed above feature temperature compensation. An increase in air temperature shifts both sensing window limits closer to the sensor. Conversely, a decrease in air temperature shifts both limits further away from the sensor. The shift is approximately 3.5% of the limit distance for a 20 C change in temperature. Temperature compensated models maintain the position of both sensing window limits to within 1% of each limit distance over the 0 to +50 C range, and to within 2.5% over the full operating range of from 25 to +70 C. Setting the Near and Far Sensing Limits The Q45U features a single push button for programming of sensing window near and far limits. For more information, refer to Program- ming the Window Limits on page 4. Status Indicators Status indicator LEDs are visible through the transparent, o-ring sealed acrylic top cover. Indicator function in the Run mode is, as fol- lows: The green LED is solid when power is applied to the sensor and flashes to indicate a current output fault. The red LED is solid when an echo is received and flashes at a rate proportional to echo strength. The amber LED is solid when the target is within the operating window limits. The 5-segment moving dot LED indicator displays the relative position of the target within the programmed sensing window. LED 1 flashes when the target is closer than the near limit. LED 5 flashes when the target is beyond the far limit. P/N 47818 Rev.

Using the two slots shown in Figure 1 on page 2, a small flat-blade screwdriver may be used to lift up and remove the black inner cover to expose the 4-position DIP switch. Use these DIP switches to program the output slope, output mode, loss of echo, and min./max. output value default.
