763 Multi-turn Absolute Encoder
- Manufacturer: ELCIS Encoder
- Category: Encoder, Absolute Encoder, Multi-turn Absolute Encoder, SENSORS
Integrating encoders into heavy machinery is often complicated by vibrations and the need for robust couplings. The 763 Absolute Multiturn Encoder solves this problem with its 63 mm square flange, which offers extremely stable mechanical mounting, ideal for environments where robustness is a fundamental and non-negotiable requirement.
Its state-of-the-art OptoASIC electronics provide a 16-bit absolute readout (65,536 divisions) over 4,096 revolutions via an SSI bus (500 kHz). Additionally, it features complementary incremental Sin/Cos (1024 ppr) or RS422 outputs, enabling redundant control architectures or high-speed closed-loop systems in dynamic drives.
Protected by an anodized aluminum housing, it withstands temperatures from -20 to +85 °C and impacts up to 50 G (11 ms). Its stainless steel shaft (Ø 9.52 mm h7) tolerates loads of 5 kg, ensuring precision without premature bearing wear. Available for custom configurations. guemisa.es.
- 63mm square flange for maximum strength fixing on vibrating surfaces.
- Dual architecture: Programmable absolute position via SSI and incremental speed via Sin/Cos.
- Optimized starting torque of 18 gcm with standard IP65 protection to minimize friction.
- Maximum refresh rate of 500 kHz without data reading distortion.
Technical Frequently Asked Questions
How do you calibrate the zero point or preset?
Absolute zero adjustment can be easily performed by applying a signal to the PRESET input, or by sending the corresponding digital command via the RS422 parameterization software or the dedicated USB connection.
Does the equipment lose its position if there is a power outage?
No. Its absolute technology with coded disc ensures that, upon restoring the 10÷30 V power supply, the encoder will report the exact position of the shaft without the need for mechanical "homing" movements.
What connection options does it provide?
It is offered with direct cable output (CV), or through various industrial connectors (CL, SL, CH) arranged radially or axially depending on the mounting space available on the customer's equipment.
