Robust Incremental Encoder I/90A
- Manufacturer: ELCIS Encoder
- Category: Encoder, Incremental Encoder, Robust Incremental Encoder, SENSORS
The ELCIS 90A (I/90A) is a robust incremental encoder with a Ø90 mm metal housing and double O-ring seal, designed for rolling mills and particularly demanding industrial environments. It supports NPN, PNP, push-pull, 26LS31 and 88C30 drivers, TTL, discriminator, and 1 Vpp sinusoidal electronics, in unidirectional, bidirectional, and zero-enabled versions. The base and cover are made of anodized aluminum, and the Ø12 h7 stainless steel shaft supports 15 kg of radial and axial load. It operates from 0 to +70 °C with IP66 protection on the shaft side (IP67 sealed) and can be connected via cable, connector, cable end connector, or terminal box (IP00).
Housed in a Ø90 mm metal casing with double O-ring, the I/90A supports NPN, PNP, push-pull electronics, 26LS31 and 88C30 drivers, TTL, discriminator and 1 Vpp sinusoidal output, in unidirectional, bidirectional and zero versions.
Anodized aluminum base and cover, and Ø12 stainless steel shaft that supports 15 kg of radial/axial load. It operates from 0 to +70 °C with IP66 protection on the shaft side (IP67 sealed) and is connected by cable, connector, cable end connector or terminal box.
