Incremental encoders with high ingress protection

Functional safety incremental encorders
A range of BEI sensors incremental encoders is available in the UK with robust construction and high ingress protection for use in harsh industrial environments. The recently announced new and comprehensive range of functional safety incremental encoders from USA sensor manufacturer BEI Sensors is available in the UK through its exclusive distributor Variohm EuroSensor. The TÜV Rheinland certified range is suitable for use in the highest industrial safety related applications up to SIL3/PLe Cat. 4, and is designed to EN ISO 13849-1, IEC/EN 61 508, and IEC/EN 62061 safety standards. With Sine/Cosine analogue electronic output or a digital (TTL or HTL) electronic output, which is an industry-first for safety encoders, the range covers seven individual encoder models with a broad selection of options to suit a wide variety of applications. Options include resolutions up to 2500 PPR, 58 mm or 90 mm diameter aluminium housings and a selection of shaft or through shaft drives with cable or connector terminations. Stainless steel housings are available to suit harsh or wash-down environments and high ingress protection ratings are available up to IP69K for high pressure and high temperature wash-downs. Further innovative safety features include additional bearings on through-shaft models for extra support and positive shaft locks to prevent the encoder sliding on motor shafts, plus tether arms for safe mounting on the driving motors. Insulated secure sleeves have been introduced to protect against stray currents. A 10-page White Paper - “What the new “Machinery Safety” regulation means for your company” - is available from Variohm to support automation engineers and system integrators who need to implement functional safety on their machines.
