A/959C Multi-Turn Absolute Encoder
- Manufacturer: ELCIS Encoder
- Category: Encoder, Absolute Encoder, Multi-turn Absolute Encoder, SENSORS
In dynamic industrial environments, the need for accurate positioning without data loss upon restart is critical to avoid unplanned downtime in heavy machinery and automation.
The A/959C Multi-Turn Absolute Encoder solves this through a maximum resolution of 25 bits per revolution, Field Bus integration, and robust parallel output for instantaneous readings without homing.
Constructed with an aluminum or stainless steel housing and a hollow shaft with spring coupling, it withstands vibrations of 10 G and operating temperatures up to +70°C. Available in guemisa.es.
- Native Field Bus integration for direct communication.
- Maximum resolution of 25 bits with up to 4096 turns.
- Housing available in stainless steel or all aluminum.
- EMC certified according to EN 61000-6-2 and EN 61000-6-4.
Technical Frequently Asked Questions
What precautions should I take when installing the encoder on hollow shafts?
Ensuring the alignment of the hollow shaft with the built-in spring coupling is vital to prevent excessive radial loads. Verify that the electrical connection can handle up to 25 bits when using a 1m cable.
What types of connectors and output configurations are supported?
The model supports (PP) Parallel, (P1) Parallel + Preset, and 20 mA Push-pull interfaces. Options include short-circuit protection and SMD technology for increased durability in demanding environments.
What are the recommended environmental operating limits?
The operating range is certified between -30 and +70 °C with a relative humidity of 981 TP3T, without a liquid state. The sealed version (X) offers IP65 protection for harsher environments.
