Some machines have a significant amount of flexure near the area requiring motion feedback. The MSA 37x series linear motion feedback encoder system was designed for machines with loose mechanical motion during operation. These encoders suit motion applications such as press brake and metal forming/bending machines.
The encoders include a bearing set internally for guiding the scanning optics, and a bearing set externally for the attachment of a coupling rod that affixes to the machine, thereby allowing for measurement of the moving elements of the machine.
Digital TTL resolutions of 5 and 1 µ are possible, with accuracies up to ±10 µ. The encoders also have magnetic limit switches that can be used to send end of travel signals to the control. Reference marks can be in the center, on either end of travel, or every 50 mm. The encoders are designed to handle large shock and vibrations, and the series is ROHS compliant.
