Incremental Encoder for Motors I/72A
- Manufacturer: ELCIS Encoder
- Category: Encoder, Incremental Encoder, Incremental Encoder for Motors, SENSORS
The I/72A Incremental Motor Encoder addresses the need for precise feedback in vibrant industrial environments where conventional sensors fail due to mechanical or thermal interference. Its patented design ensures stable shaft readings without significant electrical noise, enabling reliable position control even under high dynamic loads.
The technical solution integrates an anodized aluminum housing and a Valox 420 cover for efficient heat dissipation, along with ball bearings that support up to 8 kg of radial and axial load. Power consumption remains low in standard mode (120 mA) or increases to 180 mA with the Line Driver, optimizing the energy management of the automation system.
Built to withstand 50G shocks and 12G vibration, the device operates between 0 and 70°C under standard IP65 conditions, or IP66 waterproofing upon request. For more information on availability and specific configurations, please see guemisa.es.
- Anodized aluminum housing with Valox 420 cap for superior mechanical durability.
- Hollow stainless steel shaft available in diameters from Ø10 to Ø20 mm.
- Push-Pull Pro output and TTL 7404 options compatible with standard industrial logic.
- Certified ball bearing lifespan for more than 1.5×10^9 revolutions.
Technical Frequently Asked Questions
How does the I/72A model differ from the base I/72 model?
The I/72A incorporates a hollow stainless steel shaft with diameters from Ø10 to Ø20 mm, designed for direct drive without external couplings. The base model I/72 uses a standard solid shaft, so the choice depends on the available space in the motor and the need for internal cable routing.
What alignment precautions does the I/72A shaft require during installation?
The axial clearance of ±3 mm and the radial clearance of ±0.05 mm must be respected to prevent premature wear. Angular alignment must be maintained within the ±2° allowed by the bearing design to ensure the specified service life of 1.5 × 10⁹ revolutions without loss of resolution.
What connectors and output options are available for the I/72A?
The catalog includes terminals, cable end connectors (VM, MT, VK) and 26LS31 or 88C30 line drivers. Outputs include NPN, PNP, Open Collector, Push-Pull Pro and Sinusoidal, allowing direct integration with PLC controllers without the need for additional external adapters.
