Single-turn Absolute Encoder A/358S
- Category: Encoder, Absolute Encoder, Single-turn Absolute Encoder, SENSORS
Industrial systems require precise positioning without frequent stops for zeroing. This A/358S Single-Turn Absolute Encoder eliminates the need for mechanical homing at each power-up, guaranteeing immediate and accurate positioning after equipment startup.
Precise circuit engineering allows for a maximum resolution of 13 bits (8192) in a robust metal enclosure. It supports multiple interfaces such as standard parallel, SSI, or analog output, adapting to PLCs and servo controllers without the need for additional external converters.
Built with a servo-mount flange and IP65/IP66 protection, it withstands vibrations of 50G and temperatures between -30°C and +85°C. Its robust mechanical construction ensures a lifespan of 1.5 × 10⁹ revolutions in demanding environments. Available in guemisa.es.
- Metal container with Servo-Mount flange for direct industrial mounting.
- Absolute coding that eliminates the need for mechanical zero searching.
- Flexible output interface compatible with analog, digital and SSI serial signals.
- Vibration and shock resistance guaranteed by long-life ball bearings.
Technical Frequently Asked Questions
How does the parallel output of the A/358S model differ from that of the SSI series?
The parallel output uses standard voltage levels for direct connection to PLCs, while the SSI interface requires an external clock and RS422 transmission for longer distances. Both support up to 13 bits of resolution but differ in wiring complexity.
What alignment precautions does the A/358S axle require?
The stainless steel shaft must be aligned within tolerance to prevent premature bearing wear. Ensure the mounting surface is flat and clean before tightening the Servo-Mount flange to maintain IP65 protection.
What connectors and output options are available for the A/358S?
The connectors include PT02A16-26P for IP65 or DB25P for standard industrial use. You can select outputs such as Push-Pull (B) or Analog Voltage (V) depending on the requirements of the integrated control system.
What are the operating temperature limits for the A/358S?
The Encoder operates reliably between -30°C and +85°C, with a burn-in test at +75°C for 72 hours to ensure long-term stability in harsh industrial environments without performance degradation.
How is the analog output integrated with standard control systems?
The analog outputs convert the position into current (1-20mA) or voltage (0-10V), allowing direct integration with Line Driver inputs in standard PLCs or servo controllers for precise feedback loops.
