The WLL190T-2 is compact fiber-optic photoelectric sensor equipped with two independently programmable channels (continuous thresholds) and an additional analog output that enables the user to output object properties, like clouding, transmission, positioning or size differences to a controller. With an IP 66 rating, the WLL190T-2 can operate in moist or dusty environments. An additional highlight of this high-end product family is the ability to use these devices as a stand-alone solution or in a sensor group. When operating in a group, the devices are fitted with integrated bus technology that enables up to 16 sensors to be attached for interference-free cascading. This saves time spent on wiring and enables the settings on one WLL190T-2 to be copied to all other devices on the bus.
