MM100 Multi-Turn Absolute Encoder
- Manufacturer: ELCIS Encoder
- Category: Encoder, Absolute Encoder, Multi-turn Absolute Encoder, SENSORS
The most extreme industrial applications, such as steel mills, mining, or large cranes, subject electronic instrumentation to massive mechanical loads that destroy conventional equipment. The MM100 multi-turn absolute encoder is ELCIS's answer to this challenge: a true battleship with a Ø100 mm servo-mount flange and an exceptionally robust housing specifically designed to withstand continuous, heavy mechanical abuse.
Beneath its armored exterior lies superior optical positioning technology capable of delivering absolute resolutions of 2^24 positions over 4096 revolutions (including BCD versions up to 10^6 positions in 1000 revolutions). Its phototransistor readout matrix and 100,000-hour LED ensure a stable signal immune to external magnetic interference, eliminating the need to re-reference the machine after a power outage.
The body, forged from thick anodized aluminum, brings the device's weight to 2500 grams. Its oversized stainless steel shaft withstands colossal forces of up to 10 kg of radial/axial load, guaranteeing maximum survivability against 50 G impacts. You can purchase this heavy-duty model through guemisa.es.
- "Heavy Duty" casing of Ø100 mm that provides the highest structural strength in its category.
- Versatile integration with multiple interfaces: Parallel, Serial SSI, Multiplexer, Latch and Zero LED.
- It supports continuous axial and radial loads of up to 10 kg without deviation or damage to the bearings.
- Extended output stage options (Push-pull, NPN Emitter, Open Collector) for long cable runs.
Technical Frequently Asked Questions
Can the equipment be used in environments with high pollution and water?
The base model comes with standard IP64 sealing. However, for extremely harsh environments, we recommend the "Z" Option. This configuration includes high-performance sealed bearings that protect the shaft to IP65, although it limits the maximum speed to 2000 RPM to prevent overheating due to friction.
What output signals and protocols can be selected?
In addition to the Parallel output and the SSI Serial bus, the MM100 stands out for its communication capability through Multiplexed (M) and Latch (L) outputs, operating with Gray, Binary and Decimal (BCD) encodings.
What type of connector does it include for data output?
It offers a wide range of configurations, from heavy-duty industrial connectors like CM6 (32-pin), SM6, or MS310A18, to 37-pin D-Sub (CDH) connectors seamlessly integrated into its housing. The output can be oriented radially or axially.
