Product catalog summary

Ordering Code: The document provides a detailed ordering code for the EMI 38 series magnetic incremental encoders, specifying options for model, resolution, zero pulse, power supply, electronic interface, shaft diameter, enclosure rating, max rotation speed, output type, and variants.

Main Features: The EMI 38 series encoders are designed for harsh environments, suitable for applications like marble and glass working machines. Key features include a 3-channel encoder with up to 2048 pulses per revolution (ppr), power supply options up to +28 VDC, compact dimensions, and a wide operating temperature range from -25°C to +100°C.

Electrical Specifications: The encoders offer resolutions from 2 to 2048 ppr, with power supply options ranging from 4.5 to 29.4 V DC. They have a maximum output frequency of 205 kHz and comply with electromagnetic compatibility standards IEC 61000-6-2 and IEC 61000-6-4.

Mechanical Specifications: The encoders feature shaft diameters of 6, 8, 9.52, and 10 mm, with enclosure ratings of IP 64 and IP 66. They support maximum rotation speeds of 3000 rpm (IP 66) and 6000 rpm (IP 64), and are constructed with EN-AW 2011 aluminum and AISI 303 stainless steel.

Connections: The document details the cable output connections for push-pull and line driver interfaces, including color-coded wiring for power and channel signals.

Resolutions: Available resolutions include a wide range from 2 to 2048 ppr, with additional options available upon request.
