M344S Absolute Magnetic Encoder

Manufacturer: ELCIS Encoder
Category: Encoder, Absolute Encoder, Absolute Magnetic Encoder, SENSORS

Single-turn absolute magnetic encoder with servo flange ('Servo Mount') and rotation speed up to 12000 rpm. Suitable for industrial applications such as marine, medical, printing, metalworking, industrial automation and instrumentation.

Natural binary output via SSI serial interface over RS422, with a resolution of up to 13 bits (8192 steps per revolution). Maximum frequency of 500 kHz and maximum consumption of 35 mA.

Aluminum housing with Ø44 mm flange, Ø20 h7 centering, and Ø6 h7 stainless steel shaft. Up to 12,000 continuous rpm with low-torque bearings (option B). Operating temperature range: -25 to +85 °C. The shaft-side IP rating and continuous rpm differ between the UK and Italian specifications; please confirm with a customs broker before ordering. Available in guemisa.es.

Technical Frequently Asked Questions

What type of mechanical fastening does the M344S model have?

The M344S model incorporates a servo-type fixing flange ('Servo Mount') of Ø44 mm with Ø20 h7 centering.

What communication interface and data format does the M344S encoder use?

It uses SSI synchronous serial interface under the RS422 physical standard, delivering position data in natural binary code transmitted from the most significant bit (MSB) with an external clock of up to 500 kHz.

What rotation speed and IP rating options does it offer?

The English specification sheet indicates 3000 rpm continuous with IP66 (standard) and 12000 rpm with IP53 (low torque bearings, option B). The Italian specification sheet indicates 6000 rpm with IP64 (standard), 3000 rpm with IP66 (sealed), and 12000 rpm with IP53 (low torque). Please confirm with Guemisa before ordering.
