MM58S Multi-Turn Absolute Encoder
- Manufacturer: ELCIS Encoder
- Category: Encoder, Absolute Encoder, Multi-turn Absolute Encoder, SENSORS
Integrating instrumentation into confined spaces within servo-drive systems is a common challenge in mechatronics engineering. The ELCIS MM58S multi-turn absolute encoder solves this problem thanks to its exceptionally compact design (Ø58 mm flange and only 120 mm in length), which includes a servo-mount anchor for fine and secure adjustment without sacrificing structural strength.
This miniature model doesn't compromise on performance: it offers an astonishing maximum resolution of up to 2^24 absolute positions distributed across 4096 continuous revolutions. The optical, contactless measurement (100%) is performed using high-precision phototransistor sensors and an LED array designed to exceed 100,000 hours of use.
Its anodized aluminum body and stainless steel shaft result in a robust yet lightweight device (580 grams) that supports loads of 3 kg (axial/radial) and vibrations of up to 12 G. Compatible with most modern PLCs and drivers via Parallel or SSI Serial connections, you can order it now from guemisa.es.
- Compact housing, 120 mm in length, optimized for critical spaces in servomotors.
- Servo-mount assembly to facilitate alignment on high-speed shafts.
- Rotation up to 4000 RPM continuously and peaks of 5000 RPM in low starting torque options.
- Input voltage flexibility (5 V±5%, 8÷24 V, or 18÷28 V) and selectable encoding (Gray/Binary).
Technical Frequently Asked Questions
What is the level of protection against the environment?
The unit comes standard with IP65 protection on the output block (SM6 connector) and IP64 protection on the shaft. For dirty or humid environments, we recommend adding Option "Z," which incorporates sealed bearings, guaranteeing IP65 protection on the shaft and limiting the maximum speed to 2000 RPM.
What output interface configurations does it offer?
The model can be connected via a traditional parallel output or through the SSI Serial protocol (Option S), which is very common in high-performance servo systems. It also features various electronic stages, including an NPN open collector and an open emitter.
Is the encoder suitable for environments with large thermal changes?
The standard operating range is 0 to +70 °C (and storage up to +85 °C). As is customary for ELCIS, exclusive modifications are available upon request, such as Option "A" and Option "L," which prepare the device to perform at high or low temperatures, respectively.
