This document introduces Lenord + Bauer GEL 293 incremental encoder. The encoder uses a magnetic measuring system and a robust mechanical design, with high reliability and long service life. It can be used in many different applications and even under the harshest industrial conditions. In addition, the encoder also has high pulse frequency, high electromagnetic compatibility, high rigidity and high protection.
The GEL 293 is an incremental encoder with a hollow 16‑mm shaft and an integrated elastic coupling. It uses a magnetic measuring system combined with a precision toothed wheel, providing high reliability, shock resistance, and immunity to dirt, oil and water.
The document lists the encoder’s electrical output options (V, VN, T, TN, U, UN, X, XN, S, SN), current‑output ranges, mechanical dimensions, IP66 protection, temperature limits, and mounting instructions, together with a full pin‑layout and cable information.

The encoder offers V, VN, T, TN, U, UN, X, XN, S and SN patterns, with HTL or TTL logic levels as defined for each pattern.
It operates from 0 °C to +70 °C normally, and from –20 °C to +85 °C with the optional temperature range.
The device can be configured for 40 up to 40 000 pulses per revolution.
