Incremental Encoders for Challenging Applications – the SICK DBS60 Inox Range

Many industrial manufacturing applications such as processing conveyors, pick and place machinery and robotic systems depend upon speed and position feedback and monitoring to ensure that they are operating effectively and efficiently. Incremental encoders help provide position and motion information by converting movement and the relative position of a shaft into an analogue or digital signal that is then interpreted by the installations control system.

Intelligent Sensor Solutions

SICK is one of the world’s leading manufacturers of intelligent sensors for industrial applications, with decades of experience across a wide range of industries giving them the extra insight needed to push the design envelope.

The DBS60 Inox range of Incremental Encoders, with their rugged stainless-steel construction and excellent environmental protection are the perfect position and speed monitoring encoders for challenging working environments.

RFID Sensor – the SICK RFU61x, Big Ability in a Small Package

What is RFID Technology?

RFID, or Radio Frequency Identification, is a method of transferring information between two entities, these being an RFID tag that carries information and a RFID scanner or reader to decode that data. Using electromagnetic field technology, when an item adorned with an RFID tag passes a suitable scanner that information is captured, extracted, and acted upon, or not, by the control system that is interpreting the data.

RFID tags and readers do not need a line of sight to function, they merely need to pass within the detecting range of each other. RFID Sensor tags can be found in many applications, such as attached to clothing in a store, under the skin to identify pet ownership, in a car key fob or in production operations, monitoring the progress of a product through each stage of manufacture, all of them containing data that is accessible by a suitable reader.

RFID technology exists in many forms and for many purposes and SICK, world-renowned manufacturers of sensors and sensing solutions are no strangers to RFID technology, here we preview the RFU61x UHF RFID Sensor.
