The VLM-60 is a member of the VL series of Electric Encoders™ a product line based on Netzer Precision Position Sensor proprietary technology.
The VLM multi-turn absolute encoder is implemented with a revolution counter. The master reads the multiturn position from the encoder at power-up and during operation. In order to keep turn-count and absolute position in case of power disconnect or shut-down, the VLM includes an internal battery or with an option for an external battery connection.
