Lika's SMAR off-axis modular encoder is designed to be integrated into functional safety systems that require SIL2 Safety Integrity Level according to IEC61508 / EN IEC 62061 and PLd Performance Level according to UNI EN ISO 13849-1 (Category 3). The encoder operates redundantly and is equipped with two fully independent reading systems. Two PCB reading heads with separate power supply and interface circuits are mounted over the single MRA magnetic ring. The encoder achieves a Hardware Fault Tolerance of 1. SMAR is compact and light. It can be easily integrated into space and weight critical applications such as robots, robotic joints, brushless motors, servomotors.

Ideally suited for applications where a high functional safety level is required, for example in industrial collaborative robots

The shaft diameter is up to 25 mm. SMAR is offered in incremental and absolute versions. Incremental version provides HTL and TTL signals with additional UVW /UVW commutation signals. The resolution is up to 65536 PPR. Absolute version is equipped with SSI, BiSS or SPI interface. It offers a resolution up to 19 bits and additional TTL signals.
