Distance sensor with dual teach mode

October 2015 Sensors & Transducers

RET Automation Controls now stocks Banner’s updated Q4X laser distance sensor with a new dual teach mode. Featuring new firmware, the Q4X combines window thresholds on both target distance and target reflected intensity, allowing it to solve difficult applications reliably and with ease. The Q4X can now detect clear objects without requiring a retro-reflector. Dual mode can be used to error-proof applications by ensuring that the correct colour part is located at the correct position.

The distance sensor reliably detects distance changes as small as 1 mm and covers a 25 to 300 mm range. It was already ideal for difficult distance-based sensing applications as it easily detects objects regardless of target surface reflectivity. Examples include black foam on black plastic, black rubber in front of metal, multicolour packaging and targets of all colours. Now with the dual teach mode, the sensor can detect small changes in reflected intensity for targets inside the distance threshold. This powerful combination allows the Q4X to solve many new applications.

“Incorporating the innovative dual teach mode into the next-generation Q4X sensor provides our customers with a more powerful sensing solution for their most difficult applications,” said Dennis Smith, senior technical marketing manager, Banner Engineering. “With combined intensity and distance thresholds, the Q4X extends its world class sensing performance to clear object detection and common error-proofing, or poka-yoke, applications.”

Offering a simplified user experience, the Q4X includes a bright readout on a highly visible, angled four digit display that is easily viewed from multiple vantage points. The Q4X also offers intuitive user setup utilising three tactile pushbuttons conveniently located below the display.

The Q4X is constructed with robust housing rated to IP67, IP68 or IP69K, allowing use in wet and high pressure washdown environments. The durable FDA-grade stainless steel resists mechanical impact, over tightening, extreme vibration and aggressive cleaning procedures.
