Hengstler encoders offer optimum flexibility
October 2018, Sensors & Transducers
The range of Hengstler incremental encoders offers users optimum flexibility with an encoder available for every application. There are over 20 standard models from which to choose, including encoders for solid or hollow rotating shafts from 4-42 mm in diameter and up to 10 000 PPR (pulses per revolution). A choice of heavy or light duty is available and there are multiple connection options facilitating a fit-for-purpose encoder.
The RI32-O is popular for light duty applications. The shaft is aluminium and the 30 mm diameter housing is constructed of plastic material with protection class ratings of IP40 and resolutions of up to 1500 PPR.
Known as economy encoders, the RI38-O is also favoured for light duty applications. The shaft is made of stainless steel and the housing is constructed of glass fibre reinforced plastic material. A 6 mm diameter solid shaft version is available with a protection class rating of IP40 and resolutions of up to 1024 PPR.
The RI58-O is a universal industry standard encoder. The 58 mm diameter housing is aluminium, while the shaft is stainless steel. This encoder offers a choice of product configuration options.
Designed for direct mounting onto rotating shafts, the RI58-D is secured by a front clamping ring and the main body of the encoder by a stator coupling or set screw. The through- shaft design allows for unrestricted mounting depths as the shaft passes completely through the encoder body. The front clamping ring version is available with shaft diameters of 10 mm and 12 mm, and a protection class rating of IP64 with resolutions of up to 5000 PPR.
Also, directly mounted onto rotating shafts, the RI76TD is secured by a front flexible tether allowing for mechanical stresses caused by angular, axial or radial misalignment between the rotating shaft and the encoder. Again, the design of this encoder allows for unrestricted mounting depths as the shaft passes completely through the encoder body.
The full range of Hengstler incremental encoders is available from Johannesburg-based Countapulse Controls, which offers a full technical advisory service assisting customers to select the most appropriate encoder for the given application.
