Keyence : Ultra Long Range Multi-Function Analog Laser Sensor

Jan. 24, 2013
The IL Series triangulation-based laser displacement sensor reaches 11.48 ft (3.5 m) with 3.94 mil (100 µm) repeatability, regardless of target color.

An easy-to-use interface offers a simple approach to measuring height, thickness, liquid fill level, roll diameter, part positioning, width, long distance or hot metal part sensing. The unit's control system includes numerous built-in, application specific operation modes including thickness and step height, enabling most installations to be configured and operational within seconds after powering on the system. It features a die cast steel sensor head (IP-67) to withstand almost any environment without failures, yet weighs just 2.1 oz. making it suitable for robotic applications when used with torsion rated cable. The unit has a dedicated mode that allows calibration to be completed in three steps. Also included is a height difference filter function that automatically recognizes abrupt changes in step height and delivers a one-shot output for each step. For stability the system employs an ambient light elimination function in order to counteract ambient light interference from overhead lights. Both NPN and PNP outputs are supported, and five types of analog outputs can be selected. For quick product changeover, four patterns of tolerance values can be set. Both panel mount and DIN-rail mount models are available. Communication choices include analog, RS-232 and Ethernet/IP.
