A/759C Multi-Turn Absolute Encoder
- Manufacturer: ELCIS Encoder
- Category: Encoder, Absolute Encoder, Multi-turn Absolute Encoder, SENSORS
The automation of demanding motors and transmissions requires angular measurement systems that provide stable, absolute references without compromising size. Eliminating the homing procedure after shutdowns or power outages is essential to maximizing uptime and mechanical safety.
This absolute single/multi-turn transducer integrates high-precision electronics programmable up to 65536 x 4096 turns, using an SSI interface and additional incremental Sine/Cosine outputs at 1024 ppr or RS422. All of this operates at clock frequencies up to 500 kHz without signal distortion.
Designed for direct mounting on the motor shaft, it features a robust anodized aluminum housing (Ø59 mm), a stainless steel shaft up to Ø15 mm, and an anti-rotation bolt. It supports asymmetrical loads of up to 4 kg, distributed across guemisa.es.
- Higher-grade programmable absolute resolution (65536 x 4096) via SSI standard.
- Direct installation on motor using a stainless steel cable shaft up to Ø 15 mm.
- Dual redundant output (Absolute + Incremental) for advanced hybrid control loops.
- Extremely high radial/axial load tolerance (4 Kg) in a low profile container (340 g).
Technical Frequently Asked Questions
How is it mechanically stabilized on the motor shaft?
It is installed by sliding the shaft over the motor and securing the anti-rotation bolt to compensate for mechanical play and absorb vibrations without stressing the internal bearings with a 4 kg capacity.
What connector configurations are available?
There are variants with cable output (CV) and different standardized industrial connectors (CL, SL, CH), configurable radially or axially according to the space limitations of the chassis.
Is it suitable for environments with oils or liquids present?
Yes, the standard version offers IP65 sealing, and if the sealed bearing option (stagno 66) is selected, it provides an IP66 protection rating with a nominal starting torque of 90 gcm.
