Dual Resolution Incremental Encoder I/72H
- Manufacturer: ELCIS Encoder
- Category: Encoder, Incremental Encoder, Dual Resolution Incremental Encoder, SENSORS
In critical industrial environments, the failure of a single photoelectric detector in an incremental encoder causes immediate and costly production downtime. The I/72H model addresses this problem with a redundant architecture designed to maintain system operability in the event of isolated electronic failures.
The technical solution implements a duplicate photoelectric detector and externally switchable amplifiers, allowing the output to be changed in case of a failure without stopping the process. This ensures superior operational continuity under typical downtime conditions in heavy machinery.
The construction utilizes an anodized aluminum base and a Valox 420 top for corrosion and mechanical wear resistance. Featuring long-life ball bearings, it supports radial and axial loads within an operating temperature range of 0 to 70°C. Available in guemisa.es.
- Duplicate photoelectric detector and externally switchable amplifiers.
- Anodized aluminum base and Valox 420 lid for durability.
- Lifespan of ball bearings of 1.5 x 10^9 revolutions.
- Impact resistance of 50 G x 11ms and vibration resistance of 12 G.
Technical Frequently Asked Questions
How does the I/72H differ from the standard I/72 model?
The I/72H incorporates a duplicate photoelectric detector and externally switchable amplifiers, unlike the standard I/72 which has only one. This redundancy prevents downtime in the event of an electronic failure, maintaining the system's operational status.
What alignment precautions are required for the hollow shaft of the I/72H?
The shaft is made of hollow stainless steel with a diameter between Ø6 and Ø10 mm. The maximum joint compensation allows for axial ±3 mm, radial ±0.05 mm, and angular ±2°. It is crucial to adhere to these tolerances to ensure optimal internal operation and bearing life.
What types of connection and IP protection are available for the I/72H?
The model supports multiple connection configurations, including cable, connector, or terminal box. Standard IP64 or IP66 sealed versions are available, as well as Push-Pull, Line Driver, or Open Collector output options, depending on the system's electronic application.
