A/MM58S Multi-turn Absolute Encoder
- Manufacturer: ELCIS Encoder
- Category: Encoder, Absolute Encoder, Multi-turn Absolute Encoder, SENSORS
The ELCIS MM58S (A/MM58S) is an optical multi-turn absolute encoder with a Ø58 mm flange and 120 mm length, up to 224 Steps in 4096 turns in Gray or binary code, with parallel NPN or SSI RS422 output. Servo-type mounting and IP65 protection with SM6 connector, with Ø6 h7 stainless steel shaft that supports 3 kg of radial/axial load, resistance to 50 G of impact and 12 G of vibration, and operation between 0 and +70 °C.
As an optical multi-turn absolute encoder, with LED source and phototransistors, the A/MM58S encodes the position in Gray or Binary, up to 224 Steps in 4096 turns. The reading is output via parallel interface, with Latch option, or via SSI serial interface (RS422) in Gray code.
It is fixed by means of a Ø58 mm servo type flange, with a Ø6 h7 stainless steel shaft that supports 3 kg of radial/axial load, and works between 0 and +70 °C with IP64 protection on the shaft side (IP65 in sealed version).
- Resolution of up to 224 steps in 4096 laps (Gray/Binary).
- Three power ranges: 5 V ±5 %, 8–24 V and 18–28 V.
- NPN open collector or emitter output stages 70 mA with PTC.
- Shock resistance of 50 G (11 ms) already vibrations of 12 G (10–2000 Hz).
Technical Frequently Asked Questions
What resolutions does the A/MM58S offer?
In Gray and Binary, 16, 32, 64, 128, 256, 512, 1024, 2048 or 4096 steps per revolution and 16, 256 or 4096 revolutions, up to 224 steps. Other solutions available upon request.
Can the SSI interface be used with binary code?
No. The manufacturer states that the SSI serial output is only available with Gray code (or Excess). For binary, the parallel interface is used, where the Latch input is standard.
What connectors does it support and with what level of protection?
CM6 and SM6 32-pin (IP65/IP66), CL and SL 10-pin (IP65/IP66) and CH 12-pin (IP67), with radial (R) or axial output depending on the connector.
