A/958HS Multi-Turn Absolute Encoder
- Manufacturer: ELCIS Encoder
- Category: Encoder, Absolute Encoder, Multi-turn Absolute Encoder, SENSORS
Industrial environments demand position sensors that maintain data integrity without requiring homing after power outages. The A/958HS model offers absolute positioning with field integration, eliminating return-to-zero sequences in critical applications where operational continuity is paramount.
The technical solution integrates a 16-bit-per-revolution resolution and an SSI interface compatible with RS422 and RS422 standards. It supports continuous speeds up to 6000 RPM (SL) with a starting torque of 50/90 gcm, ensuring accurate tracking under load in demanding operating conditions.
The construction uses an aluminum or stainless steel housing with IP65 protection at the outlet. Designed to withstand 10 G vibrations and extreme temperatures from -40 to +85°C. Available in guemisa.es.
- High resolution of 16 bits per revolution for precise positioning.
- SSI interface compatible with RS422 and RS422 field protocols.
- Vibration resistance up to 10 G in the 10 ÷ 1000 Hz range.
- Bearing life of 1.5 × 10⁹ revolutions at 1000 rev/m.
Technical Frequently Asked Questions
What precautions should be taken during encoder installation?
Install the encoder by securing a 'Servo-mount' using claws or front screws to avoid excessive mechanical vibrations that could affect the accuracy of the optical sensors.
Which connectors are compatible with the encoder output?
The model supports axial or radial connection with a 1 m cable, using 12-pin connectors according to the order code for standard SSI interfaces or with a preset button (S4).
What are the recommended environmental operating limits?
It operates within an operating temperature range of -40 ÷ +85°C, although the cable outlet must be kept between -5÷+70°C to ensure insulation integrity and electrical performance.
