The ELCIS 90 (I/90) is a robust incremental encoder with a 90 mm diameter, all-metal housing and servo-type mounting flange. It supports NPN, PNP, push-pull, 26LS31 and 88C30 drivers, TTL, discriminator, and 1 Vpp sinusoidal electronics, in unidirectional, bidirectional, and zero-stop versions, with a maximum frequency of 100 kHz (300 kHz optional). It features an anodized aluminum base and cover, and a 10 mm diameter stainless steel shaft capable of supporting 10 kg of radial and axial load. Operating from 0 to +70 °C, it offers IP65 protection on the shaft side (IP66 sealed, IP53 under torque) and can be connected via cable, connector, cable end connector, or terminal box (IP00).

Housed in a Ø90 mm metal casing, the I/90 supports NPN, PNP, push-pull electronics, 26LS31 and 88C30 drivers, TTL, discriminator and 1 Vpp sinusoidal, in unidirectional, bidirectional and zero versions, with a maximum frequency of 100 kHz (300 kHz optional).
