MM59C Multi-Turn Absolute Encoder
- Manufacturer: ELCIS Encoder
- Category: Encoder, Absolute Encoder, Multi-turn Absolute Encoder, SENSORS
Mounting encoders on main drive shafts often requires complex couplings that can introduce errors due to misalignment. The ELCIS MM59C multi-turn absolute encoder addresses this problem by integrating a Ø15 mm hollow shaft and a tangential joint mounting system. This design dramatically simplifies direct coupling to the motor, reducing installation time and mitigating undue mechanical stress.
In terms of measurement, this device stands out for its extremely high precision, delivering an absolute resolution of up to 2^24 positions in a 4096-revolution cycle. It uses uninterrupted optical reading based on phototransistors and a long-life LED light source (over 100,000 hours), ensuring that the actual position is never lost after power outages.
Built with a robust anodized aluminum housing (Ø59 mm), the device weighs 570 grams and supports radial and axial loads of up to 6 kg. It is equipped with multiple interface options (Parallel and SSI Serial) and is capable of withstanding severe impacts of 50 G. It is available for direct delivery from guemisa.es.
- 15mm hollow shaft design that allows direct insertion onto the drive shaft without external couplings.
- Integrated tangential joint that absorbs small misalignments and facilitates quick anchoring.
- Continuous operating speed of up to 4000 RPM, maintaining a reading without errors or jumps.
- Full electronic flexibility: supports 5V, 8÷24V or 18÷28V and NPN Open Collector or Emitter outputs.
Technical Frequently Asked Questions
What level of mechanical protection does this model offer?
The standard model provides IP55 protection on the output block and connectors, and IP64 protection on the hollow shaft area. For enhanced sealing, the "Z" Option is available, which uses special bearings to achieve IP65 protection on the shaft (although it reduces the maximum speed to 3000 RPM).
How is the team's position data extracted?
The MM59C can be supplied with standard Parallel output or via the SSI Serial digital protocol (Option S), widely used in servo controllers. Data encoding can be configured in Gray or Binary format according to the PLC requirements.
Is it possible to modify it for extreme thermal environments?
Of course. Although the factory operating range is 0 to +70 °C, the equipment can be ordered with special modifications from ELCIS: Option "A" for very high temperature environments and Option "L" for cold storage rooms and extreme low temperatures.
