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.

DST20 Strain Sensors from Baumer, Measuring Heavy Strains in Miniature

What is Mechanical Strain?

Mechanical strain is the relative change in the length of a component or a structure when a stress is applied. Strain can be from the results of external forces, mechanical strain and from the effects of thermal expansion or contraction experienced during temperature changes. The indirect force measurement taken by strain sensors determines the mechanical strain experienced by the component or structure being monitored.

Strain sensors come in a wide variety of variants including wire strain gauges, bolt strain gauges, shear strain gauges, columnar strain gauges and many more besides. Where the application has a restriction of available real estate, but the potential strain could be large you will need a dependable, miniature strain gauge with the capacity to do the job well, enter the Baumer DST20 Miniature Strain Sensors.

Strain Sensing

The DST20 Miniature Strain Sensors are a compact and cost-efficient solution for measuring large forces above 10,000 N, even in areas with restricted space. A diminutive 28 x 12 x 10 mm in size, these capable miniature strain sensors provide space saving and reliability that is unmatched by any other screw-on strain sensor on the market.

With stainless-steel housings and an IP65 protection rating these strain sensors are ideally suited for use in a wide range of demanding production environments and applications, including static and dynamic applications, process automation and mechanical engineering sensing tasks.

Static and Dynamic Loads

Easy to install, the DST20 strain sensors can be integrated into an application with the minimum of engineering effort and provide a lasting solution that can replace cold bonded strain gauges in space restricted installations. The compact DST20 miniature strain sensors are suitable for static as well as dynamic applications with strain gauge technology that features a strain gauge and a strain body. The soft geometry on the inside of the sensor minimises hardening of the structure being measured and even thin structures can be monitored because of the limited reaction forces on the mounting screws.

Strain Sensors

The strain of these sensors is typically measured with an output signal of around 1.0 mV/V when they leave the factory, this eliminates the need for calibration with a separate force sensor. This allows Installation Engineers to benefit from a quick and easy commissioning coupled with a high measurement accuracy in the micrometre range.

Versatile Sensing

These versatile sensors are available in two measurement ranges – 500 and 1,000 µm/m, for different customer requirements in terms of the expected strains and permitted mechanical tension depending on the steel quality. A single sensor can be used to cover a wide range of applications, allowing customers to reduce costs and reduce the need for additional storage space.

With the DST20 strain sensor range Baumer has rounded off its strong portfolio of force and strain sensors so customers can optimise their process safety and quality where the smallest dimensions matter.

EX-Z Series Photoelectric Sensors – Small is Beautiful

Photoelectric Sensors come in a wide variety of sizes, shapes and variants including reflective and through beam all of which essentially perform the same purpose, the detection of objects crossing the path of the beam which then leads to a given response from the control system. This could be an alarm if an item is missing or a signal triggering another function of an automation and control process.

Big Things Come In Small Packages

For your average industrial installation there will typically be a suitable photoelectric sensor available, but when the application is very restricted in terms of available real estate, then you will need to look beyond the average sensor offering. The biggest challenge when designing and manufacturing miniaturised industrial photoelectric sensors is combining both the optical and electronic components into one housing, which as you can imagine is a complex engineering solution. Panasonic, with decades of experience with electronic design and miniaturisation were the obvious candidates to develop and manufacture a high-performance range of diminutive photoelectric sensors.

With a width of only 3mm, the EX-Z Series of Miniature Thru-beam Photoelectric Sensors is one of the smallest in the world that also contains a built-in amplifier making them ideal for mounting in tight spaces. This small but mighty range of miniature photoelectric sensors are not only small but have been designed to detect even the smallest objects with a fast response time and with the highest precision. The EX-Z series is especially suited to precise object detection within a limited and challenging installation space. Even though the housing of the sensor is only 3mm deep it contains all the essential technical elements, such as optics, electronics, indicator LEDs, and transistor output. A 2-metre cable is built-in as standard with special lengths being available upon request.

Packed with Technology

EX-Z Series - 3mm in width, fingertip sized!Although small in stature these Miniature Through-beam Photoelectric Sensors pack a powerful punch, with the ability to detect objects as small as 0.3 mm diameter without the use of an optional slit and identify objects as small as 1 mm in diameter at up to 500 mm distance (depending on the chosen model), a world class achievement among self-contained miniature photoelectric sensors. The low power consumption of these detection sensors makes them appealing to many industries and coupled with IP67 protection and their excellent vibration and shock resistance the EX-Z series is ideally suited for use in challenging and harsh industrial automation and control environments. Supplied as an emitter and a receiver pair. 3 stainless steel mounting brackets are also available separately along with a polyacetal spacer for through wall sensing, providing numerous mounting and installation options.
