Analog Output and Clear Object Detection Models Expand Laser Sensor Capabilities

Increased capabilities of Q4X series support additional quality control applications

Published: Monday, July 13, 2015 - 16:02

(Banner Engineering: Minneapolis, MN) -- Banner Engineering has expanded the capabilities of its Q4X series of laser distance sensors, allowing them to be used in several new applications. The series now includes an analog model to measure distance and a discrete model with expanded capability to detect clear objects and contrast changes.

With sub-millimeter distance change capability, the new Q4X Analog model measures height and fill levels, complementing the presence or absence capability of the discrete model. This allows the sensor to support multiple applications including easy analog interfacing to the PLC with reduced programming. Master-slave synchronization avoids crosstalk in situations requiring more than one sensor, including using opposing sensors for thickness measurement.

Additional applications for the Q4X Analog include error proofing, part positioning, roll diameter, loop control, and dimensional verification.

A new teach mode has been added to the original Q4X discrete laser sensor. This provides the ability to detect clear objects without need for a retroreflector. Additionally, the sensor can determine not only whether an object is present at the correct distance, but whether it is the correct object. The new teach mode supports detection of color recognition for quality control in bottling, consumer goods, automotive and other industries.

All Q4X sensors are available in distance ranges up to 300 mm. The 316L stainless steel housing is rated to IP67, IP68 and IP69K for durability in a wide range of harsh operating conditions.

Banner Engineering is a leading manufacturer of vision, photoelectric and ultrasonic sensors, fiber optic assemblies, machine guarding systems, measurement and inspection systems, and wireless network products. The company provides local application support worldwide.

New model with analog output, and dual teach mode in discrete model expand capabilities of Banner Engineering Q4X series of laser distance sensors.


Averaging trigger mode allows measurement across uneven surfaces for more accurate fill level monitoring.

New teach mode adds clear object detection to capabilities of the original Q4X discrete laser sensor.
