TiM361S and TiM781S 2D LiDAR sensors are economical, lightweight and compact, and can be integrated inconspicuously into low-speed, small or lightweight mobile or stationary applications, following completion of an appropriate risk assessment. The sensors can also be used where secondary safety detection is required to complement higher-rated systems already in place.
Using SICK’s patented ‘Safe HDDM+’ time-of-flight infrared scanning technology featuring 270° scanned field of view, the sensors offer high levels of object detection and measurement accuracy, with immunity to ambient light conditions. A total of 48 flexible fields can be set up and evaluated safely and simultaneously for responsive detection at distances up to 5m, and at speeds up to 1.6 m/s.
The SICK TiM361S detects both static and moving objects in a factory or warehouse, offering a robust solution for collision prevention in small, electrical AGVs, carts and platforms. Controlling personnel access around industrial-duty pick and place robot arms, is a further application. A total of 16 preconfigured field sets, each with three protective fields, make commissioning quick and easy.
SICK’s TiM781S has been introduced to meet demand for a device that enables applications to be customised by integrators and machine builders using raw data output from the device. By combining intelligent field evaluation with safety-related measurement data output via Ethernet, localisation and navigation duties can be achieved using the same device. With the SICK TiM781S, both the presence of an object and precise measurement data of the scanned surface, including size and shape, can be output to a safety PLC.
"Many applications in modern automation require complex interactions with people and processes; AGVs and collaborative robotics are a prime example,” explains Neil Sandhu, SICK’s UK product manager for imaging, measurement and ranging. “Risk evaluation in these applications can require a layered approach to safety and automation. The Tim TiM361S and TiM781S can provide measures against risks that are not considered to be negligible and, on the other hand, do not require the adoption of more costly protection measures. For example, the detection of overhanging loads on a small guided vehicle.
“SICK TiM361S and 781S sensors offer versatile new options, including where a secondary LiDAR sensor with a lower safety rating can be deployed to operate alongside a higher-rated device,” he adds.
Both weighing just 250 g, the SICK TiM361S and TiM781S have a compact 60 by 60 by 86 mm IP67 aluminium housing, with the option of a protective hooded mounting kit. Advanced energy management and a low, 4W power consumption minimises drain of the vehicle’s batteries. The SICK TiM361S has a non-safe monitoring field of 10 m, and the SICK TiM781S up to 25 m. Set up is straightforward using SICK’s intuitive SOPAS configuration tool, via USB port and laptop.
