Turck has added single- and multi-turn encoders with a solid or hollow shaft for mobile and agricultural machines to its Industrial and Efficiency Line portfolio.
The IP67-protected encoders are available in sizes 36 mm, 46 mm, and 58 mm. Two interlocked bearings ensure a mechanical design and offer protection from vibration or shock on the shaft. Users thus benefit from a greater encoder service life compared to devices with a shaft bearing. The encoder’s operation data can be diagnosed via the J1939 network. Installation, connection, and commissioning are simplified due to the design, standard cabling, and plug-and-play capability. Functional safety is achieved due to internal plausibility check of parameters.
The energy harvesting technology of the multi-turn J1939 encoders enables wear-free and maintenance-free operation, explained the company. These count rotations without an additional battery or mechanical gears.
While standard single-turn resolution is 14 bit, the total resolution of the multi-turn encoders can be increased from 32 bit up to 43 bit if required, corresponding to over 500 million countable revolutions. While up to 127 nodes can be configured in a network on CANopen encoder models, in a J1939 network up to 254 nodes can be configured.
