CONTROL SYSTEMS + AUTOMATION

Encoders with energy harvesting technology Turck has expanded its encoder offering with the release of Compact Magnetic Absolute Multiturn Encoders. Available from RET Automation Controls in Analogue, CANopen, and SSI output, these compact devices are ideal for OEM applica- tions where space is limited, and where reliability and pricing are a factor. The cost-competitive nature of this product will also see it used in a wide range of general position applications. “These are the first encoders from Turck with Energy Harvesting Technology,” explained Marty Cwach, senior product manager for sensors. “No longer are there worries of battery life or mechanical gears to track revolutions in these magnetic multiturn devices. This is the next great step in providing our customers with an increasing portfolio of Turck encoder solutions.” Turck’s compact magnetic absolute multiturn encoders come in 39 mm diameter housing. The standard product line offers IP65/IP67 protection, while the robust series includes IP66/IP67/IP69K ingress protection and 316

Linear position sensor for mobile hydraulics Turck, Supplied locally by RET Automation Controls , is add- ing the robust LTE for direct integration in hydraulic cylinders to its portfolio of linear position sensors. The magnetostrictive sensor can withstand shocks of up to 100 g and the vibrations that typically occur with agricul- tural and forestry machinery. The device is also insensitive to external influences, so that the LTE is even suitable for use in the hydraulic cylinders of construction machinery in extreme- ly severe environments. The user can set the measuring range flexibly according to the sensor type. Thanks to the field-proven magnetostrictive technology, the wear-free operating LTE guarantees high pre- cision, linearity and repeatability. The sensor has a 16-bit resolution and also offers three signal ranges for mobile equipment (0…5 V, 0,25…4,75 V, or 0,5…4,5 V) in addition to the standard analog output signals of 0…10 V and 4…20 mA.

Temperature sensor with integrated process connection and evaluation electronics The compact TN type temperature sensors are distinguished by excel- lent response times, high pressure resistance and integrated process connections. The sensors easily resist applications with temperatures up to 150°C and high pressure loads up to 400 bar. The measuring range is freely scalable. Updating a classic: What is new is the quick and easy handling via three pushbuttons. The display can be switched from the indication of ‘red’ to an alternating indication of ‘red – green’. So, switching states can be highlighted or an independ-

ent colour window can be created. The sensor head can be rotated and offers op- timum readability from any position. Thanks to captive laser labelling on the stainless steel housing, the units can still be identified after years. Enquiries:Tel: +27 (0) 12 450 0400 or email nfo.za@ifm. com

Thanks to the innovative on-chip time-of-flight prin- ciple with PMD technol- ogy, this sensor offers all the capability of a meas-

urement system. It now comes with IO-Link functionality for simpler parameter setting and distance value transmission. The signal strength can be sent via IO-Link.This makes it possi- ble to distinguish many different components within the same application by their object contrasts. O1D is insensitive to ex- traneous light up to 100 000 lux and remains unaffected even if direct sunlight hits the sensor or target, thus operating reliably and accurately at all times.
