Rack encoders with automatic slack recovery. If compared to an incremental linear system, this type of encoder extremely simplifies linear measurements and overcomes measurement problems on long distance. Our models are sealed in a robust aluminium body and integrate a preload system allowing the automatic slack recovery between rack and pinion.

Up to 2.000 ppr with zero

• Several output types available.
• Up to 24 Vdc input voltage.
• Up to 300 kHz frequency response
• Output cable with connector.

Eltra’s metric wheels series is studied for specifi c industrial application where is required to measure a linear movement (i.e. continuous sheet cutting machines of wood, textiles, glass, etc.). Precise reading and high stress resistance are the main features of those encoders. The body is entirely designed of aluminium and mounted using an oscillating arm pivoted on the axial. It comes with an integrated self-lubricating compact box to assure a long operation period without any maintenance. The weighty metric wheel keeps a stable contact with the material, allowing an accurate measurement of both length and speed. The wheel surface can be in crossed-knurl aluminium, special anti-oil or anti-slide rubber.
