Photosensor handles tough reflective
backgrounds
Detecting even the most difficult targets against a reflective background - such as small objects on a white conveyor belt - is easy with the new XUK-8 background-suppression photosensor
Detecting even the most difficult targets against a reflective background - such as small objects on a white conveyor belt - is easy with the new XUK-8 background-suppression photosensor from Telemecanique, a brand of Schneider Electric Fully self-contained in a compact housing, the new XUK-8 needs no separate reflector or receiver, making installation particularly straightforward, even where space is limited

Schneider Electric is expanding its popular Magelis range of HMI terminals with four key new additions, offering superior performance and functionality at reduced cost.
Servomotor system suits a range of machinery
The Lexium motion controller is sufficiently powerful to require no other PLCs for many applications.
XUK-8 photosensors, which offer a maximum operating range of 4m, use a dual-detector sensing system, and have a special optical system which ensures that the sensor's infrared beam is always sharply focused.
These features allow the sensors to discriminate readily and reliably between background and target reflections, even with the smallest targets, and also mean that sensing performance is virtually unaffected by the colour of the target.
The sensors are, therefore, also ideal for use with printed targets, which may include light and dark areas, and in applications such as detecting web breaks in printing plant, where it is essential for the sensor to differentiate between a break in the web and the black printed area on an unbroken web.
Measuring just 50mm x 50mm x 18mm, Telemecanique's XUK-8 background-suppression photosensor is available with either a 2m pre-fitted cable, or with an M12 socket which is fully compatible with Telemecanique's easy-to-wire Snap C connectors.
Both models can be programmed by the user for pnp or npn output, and for light-on or dark-on operation.
An IP65 protection rating, an operating temperature range of -25 C to +55, and construction which features materials suitable for use in the food industry make these versatile and cost-effective sensors an attractive choice for even the most demanding applications in industry and commerce.
