Functional Safety Incremental Encoders

BEI Sensors is introducing its new functional safety incremental encoder range that is certified by TÜV Rheinland and can be used in the highest industrial safety related applications up to SIL3/PLe Cat. 4 and is designed to safety standards EN ISO 13849-1, IEC/EN 61 508, and IEC/EN 62061.The range has a standard Sine/Cosine analog electronic output or an industry-first for safety encoders— a digital (TTL or HTL) electronic output. There are seven models available including options with: 58 mm or 90 mm body sizes; shafted or through shaft styles with cable or connector terminations; resolutions up to 2500 PPR; and, a selection of shafts and bore sizes. The product has aluminum encoder housing and optional stainless steel housing for harsh outdoor or washdown environments.  Safety features include: additional bearing in the cover on through shaft models for better overload capability; positive shaft locks to prevent sliding of the encoder on motor shafts; insulated secure sleeves to protect against stray currents; accurate stator couplings and tether arms for safe mounting on the driving motors.
