New shaft and hollow-shaft encoders eliminate need for redundant encoders and secondary sensing devices.
Leine & Linde’s new 850 shaft and 862 hollow-shaft encoders allow incremental encoders to be applied where safe operation of machinery is necessary without requiring a redundant encoder or secondary sensing device.
Incremental encoders with the ability to provide guaranteed output signals over a single cable in an industrial environment are ideal for applications where redundant safety interfaces are not desired or may not be possible without complete overhaul of the equipment.
The 850 shaft and 862 hollow-shaft are Certified for SIL2/PLd, Category 3 applications. Output signal validity is assured by comparing raw sensor signals to digital output states and validating that against the actual values output to the control. If all values are not in agreement, or the power supply is not within specifications, a status signal indicates that the output is invalid.
