Increased Functionality and Distance: Leuze’s New Two-in-One Sensor
Leuze releases the ODT3CL1-2M diffuse reflection sensor for their 3C series sensors that boasts a 2-meter sensing range and dual switch points for object detection and distance measurement.
Throughout virtually all automation processes, it is necessary to determine if the product is present and to measure distances between the product and the process machinery.
Leuze, “The Sensor People,” recently announced the ODT3CL1-2M compact diffuse reflective sensor that accomplishes both tasks in one sensor.

What is a Diffuse Reflective Sensor?
A diffuse reflective sensor emits a laser or beam of light toward an object and detects the light reflected from the object. Diffuse reflective sensors are more versatile in object detection than other optical sensors since they do not have object restrictions. Many other optical sensors may only be able to detect metallic, solids, or nontransparent items, however, diffuse reflective sensors have proven their worth in many applications and can detect objects such as liquid, wood, glass, and other commonly used items in manufacturing. The sensors can also provide information such as precise position measurement of an object, color identification of a component, and can detect small objects.
A Single Sensor with Dual Functionality
The ODT3CL1-2M is a switching sensor with both a target set point and an additional measurement value output. In other words, the sensor has two independent switching points that perform the operation of two sensors in one.
The dual functionality combined with the compact design (11.4 x 34.2 x 18.3 mm) allows the sensor to mount in places that ordinarily cause issues in the automation process. The size and increased functionality allow the sensor to be used in applications where space is limited. One such example would be determining the position of a pallet on a load receptacle shown below.

High Accuracy and a Longer Operating Range
The ODT3CL1-2M sensor boasts an operating range of up to two meters using a red (class 1) laser. The sensor relies on Leuze's innovative time-of-flight (TOF) technology. Simply put, the sensor calculates the distance based on the time the laser or light signal travels from the sensor to an object and then back to the sensor.
The additional range and accuracy make this sensor ideal for shuttle applications to identify free spaces on shelves and safely transport goods. Operators can easily set up the sensor by using a visible spot to allow the operator to see where the object is detected.

IO-Link Connectivity
In addition to the dual functionality and additional range, the ODT3CL1-2M transmits data via IO-Link.
IO-Link has established itself as a proven solution, allowing the end user to remotely adjust the operating range, calibrate the device, and transfer the distance measurements back to the controller, while still permitting operators to make these adjustments directly at the sensor by pressing the teach button on the device for drop-in replacement of existing discrete systems.
The new ODT3CL1 optical sensor from Leuze provides a more flexible approach to object detection and TOF measurement, opening new avenues of productivity for a variety of industries.
