Compact laser diffuse sensor

On automated guided vehicles, the ODT3CL1-2M optical sensors monitor that pallets are correctly received and transferred

Leuze says thanks to TOF technology, its new ODT3CL1-2M compact diffuse sensor achieves an operating range of up to two metres. The 2-in-1 sensor detects the presence of objects and at the same time transmits measurement values.

With the new ODT3CL1-2M laser diffuse sensor, the Sensor People from Leuze are extending the operating range of the 3C series distance sensors. The company says thanks to innovative time-of-flight (TOF) technology, the switching and measuring sensor with background suppression works with an operating range of up to two metres. This makes the ODT3CL1-2M suitable for all applications in intralogistics where long distances need to be bridged: e.g. in automated guided vehicles for monitoring the position of goods, for controlling robot grippers or in quality control. Reliable use is guaranteed even under harsh conditions. This is because the sensor satisfies the high requirements of degree of protection IP69K.

Leuze says as a 2-in-1 solution, the ODT3CL1-2M reduces the cost and effort for users in terms of procurement, installation, commissioning and in operation. With its two independent switching points, it is able to perform detection and measurement tasks at the same time. System operators can therefore solve both requirements using just one sensor. This is an advantage if, for example, shuttles are used: They can optimally set and vary their speed via the independent switching points. This enables goods to be transported quickly to their target position.

IO-Link can be used to transmit measurement values and process data of the sensor to the machine control. This allows users to effortlessly evaluate the comprehensive diagnostic data from the diffuse sensor – e.g. temperature information, information on signal quality and warnings. It also makes device swap-out easy: The pre-settings are transferred to the new device loss-free via IO-Link without the sensor having to be taught in again.

The company says thanks to its compact design (11.4 x 34.2 x 18.3 millimetres; W x H x L), the ODT3CL1-2M laser diffuse sensor can also be used where space is limited. For example, it can be used in the gripper of a robot arm, on shuttles or stacker cranes. The small, clearly visible light spot allows fast alignment during commissioning. The operating range can be set numerically via IO Link. Another advantage of the diffuse sensor is its integrated object test. This allows the function reserve to be quickly checked.

With the 3C series, Leuze says it provides a sensor solution that is also suitable for distances of less than two metres. The ODT3C diffuse sensor is therefore ideal for operating ranges up to 150 millimetres – perfect for packaging processes, for example.
