Robust single-turn encoders

April 2008 Sensors & Transducers

The 3650 and 3670 series of absolute single-turn encoders from Kübler offer a resolution of 9 bit with SSI, 4–20 mA or 0–10 V output. There is a suitable measuring range (45°, 90°, 180° or 360°) for every application. The encoders are particularly robust, compact and versatile.

The compact new design has opened up areas of application previously inaccessible to absolute encoders

The non-contact magnetic measuring systems are not subject to wear and so offer a long service life and high reliability. The sturdy die-cast housing and the IP69K protection rating ensure the encoder remains sealed, even in the harshest environments, and offer the highest security against breakdowns in the field. Thanks to its wide temperature range of -40°C to +85°C and to an especially high resistance to humidity and condensation, the encoder is ideal for use outdoors with large temperature fluctuations. Extremely high resistance to shock (>500g) and to vibration (>30g) guarantee that the encoders are better able to withstand difficult environmental conditions, thus avoiding machine stoppages and the need for repairs.

The compact design as well as a blind hollow shaft of up to 10 mm means the encoders can be used where space is restricted and can be mounted on a tight radius even with large shafts. A green LED for reference point detection facilitates start-up, whilst a red LED simplifies fault diagnostics during maintenance.
