EMA 22 A

Product catalog summary

Main Features:
The EMA 22 A is a magnetic singleturn absolute kit encoder suitable for various applications such as electric motors, marine, iron and steel industries, and automation. It offers a resolution of up to 13 bits (8192 ppr) with an SSI electronic interface, features a cable output with a connector, and utilizes no-contact magnetic technology to prevent wear. The encoder supports bore shaft diameters up to 10 mm and has an IP 67 enclosure rating, with an operating temperature range from -40°C to +125°C.

Ordering Code:
The ordering code for the EMA 22 A includes specifications for series, model, resolution, code type, power supply, electronic interface, logic, options, bore diameter, enclosure rating, max rotation speed, output type, direction type, and variant.

Electrical Specifications:
The encoder supports resolutions from 8 to 8192 ppr, with a power supply range of 4.75 to 5.25 V DC and a maximum current consumption of 100 mA without load. It features an RS-422 output type, binary or gray SSI output code, and a clock frequency range of 100 kHz to 1 MHz. The SSI frame has a 13-bit data length, with typical accuracy of ±0.35° and maximum accuracy of ±0.50°.

Mechanical Specifications:
The bore diameter options are 6, 8, 9.52 (3/8”), and 10 mm. The encoder has an IP 67 enclosure rating, a maximum rotation speed of 10000 rpm, and can withstand shocks of 50 G and vibrations of 10 G. The body, housing, and magnet actuator are made of EN-AW 2011 aluminum. Operating temperature ranges from -40°C to +125°C, with storage temperatures from -25°C to +85°C. The weight is 30 g, and mounting tolerances for the magnet actuator are ±0.2 mm axially and ±0.1 mm radially.

Connections:
The encoder uses a cable output with specific color-coded connections for +Vdc, 0 Volt, data +, data -, clock +, and clock -.

Resolutions Available:
The encoder supports a wide range of resolutions, including 8, 16, 25, 32, 40, 50, 64, 80, 100, 125, 128, 160, 200, 250, 256, 320, 400, 500, 512, 800, 1000, 1024, 1600, 2000, 2048, 4096, and 8192.
