Robust Incremental Encoder I/120
- Manufacturer: ELCIS Encoder
- Category: Encoder, Incremental Encoder, Robust Incremental Encoder, SENSORS
The ELCIS 120 (I/120) is a robust, all-metal incremental encoder with a 120 mm square housing, a Ø22 h7 shaft, and a pulse rate of 1 to 2540 pulses per revolution. It features an internal, self-balancing read head that withstands heavy shaft loads, making it suitable for shipyards, rolling mills, paper mills, cable cars, and other similar applications. The base and cover are made of anodized aluminum, and the stainless steel shaft supports 30 kg of radial and axial load. It operates from 0 to +70 °C with IP66 protection on the shaft side and offers radial output via cable, connector, cable end connector, or terminal box (IP00).
The I/120 offers 1 to 2540 pulses per revolution, a maximum frequency of 100 kHz and NPN, PNP, push-pull electronics, 26LS31 and 88C30 drivers, TTL, discriminator and 1 Vpp sinusoidal output.
