A/758S Multi-Turn Absolute Encoder
- Manufacturer: ELCIS Encoder
- Category: Encoder, Absolute Encoder, Multi-turn Absolute Encoder, SENSORS
Precise positioning in automation systems requires overcoming the limitations of incremental sensors in dynamic machinery. Maintaining absolute position reference without re-referencing after a power outage is crucial to ensuring productivity and preventing mechanical collisions.
This model integrates a powerful synchronized SSI interface and incremental Sin/Cos outputs to 1024 positions or RS422 up to 16384. Its highly reliable programmable electronics deliver an absolute physical resolution of 65536 turns by 4096 revolutions, with noise-immune data transmission at clock frequencies of 500 kHz.
Housed in a robust 58 mm anodized aluminum (servo-mount) casing with a Ø 6 h7 stainless steel shaft, it withstands radial/axial loads of 2 kg and is protected by IP65/IP66 sealing. This product is sold directly through guemisa.es.
- Absolute resolution programming up to 65536 x 4096 rotations via SSI interface.
- Complementary incremental outputs Sin/Cos (1024 ppr) or RS422 for dual loop integration.
- Optimized servo-mount type fixing with Ø 6 mm shaft in maximum durability stainless steel.
- Robust mechanics with a load capacity of 2 kg and optional IP66 sealing for aggressive environments.
Technical Frequently Asked Questions
Is it compatible with high-speed SSI networks?
Yes, the interface supports clock speeds up to 500 kHz. It is vital to respect the rest periods (tp ~32 µs) between read sequences to ensure register stability.
What mechanical and protective configurations are available?
The standard unit has an IP65 rating, but can be ordered with IP66 sealed bearings (option Z). Additionally, the shaft can be adapted to other diameters (Ø5, Ø8, Ø10, Ø12) upon request.
How does it behave under thermal and mechanical spikes?
It guarantees continuous operation between -20 and +85 °C and absorbs mechanical shocks of up to 50 G (11 ms), validating it for direct installation on industrial mobile motors or chassis.
