Incremental Encoder for Racks I/38CR
- Manufacturer: ELCIS Encoder
- Category: Encoder, Incremental Encoder, Incremental Encoder for Rack and Pinion, SENSORS
Accurate measurement of linear displacements in industrial environments demands robustness and simultaneous resolution. The I/38CR Incremental Rack Encoder addresses the need for high-fidelity displacement detection by integrating a pinion preload system directly into the device body to ensure mechanical stability during operation.
The technical solution incorporates a stainless steel shaft and an aluminum base that supports radial and axial loads of up to 0.5 kg. With a bearing life of 1.5 x 10^9 revolutions, the device maintains its structural integrity under vibrations of 10 G in the range of 10 to 2000 Hz and shock resistance of 40 G for 11 ms.
The design combines a steel cover with IP65 protection on the outlet side, allowing for installation in demanding environmental conditions. The operating range of -10 to 70 °C ensures reliability under varying thermal cycles, while the LED light source guarantees over 100,000 hours of operational life without performance degradation.

Technical Frequently Asked Questions
How does the I/38CR differ from the I/E6 model in terms of resolution and size?
The I/38CR is specifically designed for racks with a resolution of 0.05–1 mm and a weight of 230 g. Unlike the I/E6, which is typically more compact for standard axes, this model incorporates a stainless steel pinion optimized for direct linear transmission in CRP systems.
What alignment precautions does the I/38CR shaft require during installation?
Since the system uses a pinion with built-in preload, maintaining perfect coaxial alignment between the encoder and the rack is crucial to avoid reading deviations. It is recommended to verify that the maximum radial load does not exceed 0.5 kg and to ensure that the ambient temperature is within the operating range of -10 to 70 °C.
What connectors and output options are available for the I/38CR?
The device supports multiple connection configurations, including CVC cable, terminal block, or CD connectors. Electrical outputs include standard Push-Pull and Line Driver (5–24V), with additional options such as VMC for standard 7-pin connectors or TMC for sealed versions, allowing for flexible control system integration.
