New SIL 3 Safety Encoders

For applications requiring SIL 3, PL e, Category 4-rated equipment, Heidenhain has developed the ECI 1319 and EQI 1331 inductive, safety-related rotary position encoders. These applications involve high risks for operators, such as when they may interact with a robot.

The EQI 1331 rotary encoder has 19 bits of resolution in the single-turn range while tracking 4,096 (12 bits) revolutions. The ECI 1319 is a single-turn encoder with 524,288 (19 bits) of resolution. Both the ECI and EQI encoders showcase improved vibration specifications (400 m/s² stator and 600 m/s² rotor), as well as a more durable multi-turn gearbox. According to the company, these encoders also support the advantages of previous bearingless, inductive encoders, including non-contact design, resistance to contamination, no mechanical self-heating and reduced sensitivity to radial runout.

"The ExI 13xx series rotary encoders provide a single encoder safety solution for many applications such as packaging, automation and robotics," said a company spokesperson. "Along with these advantages, the new ExI 13xx encoders offer a variety of additional safety-related functions. However, these functions are available only with a safe control that supports the EnDat Safety Master, and can be implemented independently of the control-loop parameters. These safety measures work directly with a control's safety module."
