Baumer BMMK 58 SSI - MAGRES is a mini absolute encoder
Absolute encoders are rotary encoders that have a unique code output for each shaft position. The shaft position is monitored even when there is no supply voltage, and the position signal is transmitted as a digital code. The ability to monitor the shaft position even when the power supply is switched off is the main reason why Baumer Hubner GmbH absolute encoders are used in applications with high demands on accuracy and safety.
Absolute encoders encoding a position within one revolution are called single-turn encoders, while encoders with a revolution counter are called multi-turn encoders. The most common output types are parallel code, SSI, CAN-open, and Profibus DP interfaces. A distinction is made between magnetic and optical encoders according to their operating principle. The latter, like incremental encoders, detect the rotation of an optical disc, while magnetic encoders detect the passage of magnetic poles past a sensor element. A built-in rechargeable battery allows the encoder to track shaft position when the power is off, but the position code is only transmitted when the power is on.
Advantages of the Baumer absolute encoder
Baumer Hubner GmbH offers single and multi-turn absolute encoders. Baumer Hubner GmbH encoders can measure up to 8192 (13 bit) shaft positions within a single revolution, 4096 (12bit), or 65536 (16 bit) shaft revolutions. An ultra-precise single-turn encoder model has also been developed that can record up to 4194304 (22 bit) shaft positions within a single revolution. Baumer absolute encoder output and programming is via an SSI interface and can also be connected to external units via Profibus, Device Net, or CANopen. Combination units with absolute and incremental parts are available.
Advantages of absolute encoders:
- No wear parts (except AMG 10 / AMG 81 models), ball bearing life is about 109 revolutions.
- Continuous high-speed operation is possible, even during start-up.
- Availability of models with solid shaft and hollow shaft.
- Robust construction with high impact resistance.
- Easy-to-understand Baumer absolute encoder manual.
- Immune to electromagnetic interference.
- Optional: redundant versions.
Features of Baumer technology
The Baumer Group's customers range from small, highly specialized factories and engineering plants to large industrial plants and international groups of companies. Because of their high shock and vibration resistance, explosion safety, and wide range of operating temperatures Baumer Group's devices are successfully used in the paper, steel, mining, food, semiconductor industries, in the print shop, metallurgy, rolling equipment, cooling units, portal cranes and other lifting equipment, packaging and textile equipment, automation of warehouses and terminals, explosive production, medical laboratory equipment, etc.
Robust construction
The one-piece enclosure made of aluminum or stainless steel is highly impacted resistant. Special surface protection for particularly aggressive environments. Protection rating up to IP 69K. Extremely wide operating temperature range. Electrical connection for every application: terminal boxes, internal connection clamps, metal plugs, or cables without plugs.
Optimized bearings
Reinforced ball bearings High radial and axial shaft load limit provided by mounting bearings on both ends of the shaft, if structurally possible. This provides additional advantages: there is a possibility to create a complete combination of several twisted together encoders, speed relays, etc. In addition, the other end of the shaft can be used to mount additional external devices. One side of the encoder with a large diameter hollow shaft bearing, installed if the advantages of a single-sided bearing arrangement outweigh the advantages. Versions without bearings are available for specific applications.
Protection against stray currents
For hollow shaft encoders, parasitic currents generated by the motor and flowing from the axis through the encoder body to the ground can be prevented by using insulating ceramic ball bearings and the parasitic current must be removed from the axis by means of an earthing contact ring. For encoders with a solid protruding shaft, a dielectric spring coupling with an insulated hub is used to protect against the parasitic pulsating current.
