Safety encoder range features analogue and digital output
BEI Sensors have released a range of functional safety incremental encoders through 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 electronic output (TTL or HTL), which is an industry-first for safety encoders.
Options include resolutions up to 2500PPR, 58mm or 90mm 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.
Other safety features include additional bearings on through-shaft models for extra support and positive shaft locks to prevent the encoder sliding on motor shafts, tether arms for safe mounting on the driving motors, plus insulated secure sleeves have been introduced to protect against stray currents.
