I/41Q Miniature Incremental Encoder

I/41Q – Miniature Incremental Encoder, Shaft Ø 6.35×14 mm, Body: Ø 40×52.5 mm, Pulse range: 1 to 2,540

The incremental encoder ELCIS I/41Q It is a miniature rotary sensor with a metal housing and square flange, designed for industrial environments requiring precision, reliability, and mechanical strength. Derived from the I/41S model, this encoder maintains its compact format (Ø 40 mm body) and incorporates a solid Ø 6.35 mm stainless steel shaft, housed in an anodized aluminum housing that guarantees durability under demanding conditions.

With configurable resolutions from 1 to 2,540 pulses per revolution, can be fueled by tensions between 5 and 30 V DC, offering output signals in push-pull, line driver, or open collector versions. It supports continuous speeds up to 6,000 rpm, capable of working in environments with vibrations (up to 12 G) and impacts (up to 50 G), thanks to its long-life bearings (up to 1.5 × 10⁹ revolutions).

The ELCIS I/41Q encoder is ideal for compact machinery, servo motors, automation systems, and OEM applications where a rugged, precise, and compact sensor is required.
