A/758H Multi-Turn Absolute Encoder
- Manufacturer: ELCIS Encoder
- Category: Encoder, Absolute Encoder, Multi-turn Absolute Encoder, SENSORS
Precise positioning in high-speed systems requires overcoming the limitations of single-turn sensors compared to complex multi-turn applications. Maintaining an absolute reference without data loss throughout complete cycles is critical for heavy industrial machinery operating under demanding and constant dynamic conditions.
This encoder integrates a clock-synchronized SSI interface and incremental Sin/Cos outputs up to 1024 positions or RS422 up to 16384. The internal electronics allow programming the absolute physical resolution up to 65536 rotations by 4096 turns, guaranteeing electrical stability under clock frequencies of 500 kHz without signal degradation.
Built in a robust 58 mm anodized aluminum housing with a Ø 10 h7 stainless steel shaft, it supports a radial/axial load of 2 kg and offers IP65 or IP66 protection against dust and water. The entire system is available in guemisa.es.
- Native support for programmable absolute resolutions up to 65536 x 4096 rotations with SSI interface.
- Incremental Sin/Cos output at 1024 ppr or optional RS422 compatible with standard controllers.
- Anodized aluminum container with IP65/IP66 protection and stainless steel shaft.
- Mechanical resistance for radial/axial load of 2 Kg and optimized starting torque of 18 gcm.
Technical Frequently Asked Questions
What precautions should be taken during mechanical installation?
Ensure the encoder is mounted on a rigid support to avoid mechanical resonances that affect optical reading in environments with vibrations exceeding specified limits.
Which connectors are compatible with this model?
The device supports MS310A18-1P IP65 or Eml 121 IP66 connectors depending on the option selected to ensure the required watertightness in outdoor or wet industrial applications.
What are the environmental operating limits?
It functions correctly between -20 and +85 °C, withstanding storage temperatures up to +85 °C without affecting the integrity of the internal optical sensors or electronics.
