Wire-actuated encoder SGH10
Position sensor for hydraulic cylinders with measuring lengths up to 1000 mm
SIKO GmbH from Buchenbach, the German specialist producer of sensors for linear and rotary path and angle measurement, has given its SGH10 position sensor a technical facelift. The SGH10 position sensor, which can be integrated into hydraulic cylinders with a stroke length of up to 1 m, has recently been certified by the German Federal Motor Transport Authority in accordance with UN ECE R10 and now has E1 certification for road vehicles. It can also be used when it is very hot. The extended temperature range up to 105° C makes this possible and sets a new record.
E1 certification from the Federal Motor Transport Authority in accordance with UN ECE R10
The integrable position sensor for hydraulic cylinders has been tested by the Federal Motor Transport Authority (Kraftfahrtbundesmt – KBA) in accordance with UN ECE R10 and now has E1 certification for road traffic. The sensor can therefore be used for applications in which it operates during active driving of a vehicle on public roads. With the E1 certification, the sensor can be used in utility vehicles without affecting the operating license for the vehicle as a whole. The high EMC requirements that must be met and the load dump test, in which voltage peaks of up to 400 V are applied to the sensor, demonstrate its electronic sturdiness. “Not only does this certification allow our customers to deploy the sensor flexibly in utility vehicles for a wide range of applications, it also shows the high level of quality to which the sensor has been developed, produced and tested,” Mathias Roth emphasized, Mobile Automation Sector Manager at SIKO.
Among other things, the sensor owes its strengths to a unique SIKO technology platform called PURE.MOBILE. This technological platform for special SIKO sensors has been designed and developed exclusively for position detection systems in utility vehicles. Unlike many of the sensors currently available on the market, which originate in industry or traditional machine construction and are then adapted for utility vehicles, sensors from SIKO that bear the PURE.MOBILE label have been designed and tested exclusively for heavy use in mobile machines. Every sensor with the PURE.MOBILE label therefore meets the EMC requirements for construction machines, forestry machines and agricultural machines, the requirements of E1, and is based on magnetic, wear-free and sturdy sensing technology
Fluid temperature range up to 105° C
The sensor also impresses in terms of the maximum permissible temperature of the fluid used. The SGH10 standard sensor, which has been available since 2015, is already resistant to fluid temperatures up to 100° C. With an optionally selectable special seal, even fluid temperatures up to 105° C. can now be used without reservations. To be precise, the sensor can now be used in media from -30° to +105° C, which is a genuine highlight.
The SGH10 position sensor with the described characteristics is available effective immediately. For larger strokes, an extended measuring range up to 2.5 m is available with the SGH25 from SIKO, and up to 5 m with its big brother, the SGH50. All SGH sensors can also be used in telescopic cylinders and piston accumulators.
The SGH wire-actuated encoder measures the absolute, direct cylinder stroke in the hydraulic cylinder. Cost-intensive drilling of the piston is no longer required thanks to the new measurement system. As a result there are lower integration costs compared with other measurement systems and weakening of the piston is effectively avoided. The highlight: The measurement system can even be used in telescopic cylinders!
In the framework of SPS IPC Drives 2015, exhibition and online visitors nominated the SGH10 as the winner of the DirectIndustry i-NOVO Award in the TECH category.
