EL 120 P

Product catalog summary

Ordering Code: The ordering code for the EL 120P encoder includes specifications such as series, model, resolution, zero pulse, power supply, electronic interface, bore diameter, enclosure rating, max rotation speed, output type, and variant.

Main Features: The EL 120P is a through hollow shaft incremental encoder designed for medium to large motors. It features a 120 mm diameter, supports up to 2048 pulses per revolution (ppr), and offers a power supply up to +24 VDC. It includes a 3-channel encoder (A/B/Z) with an output frequency up to 105 kHz and a cable output with a connector available at the cable end.

Electrical Specifications: The encoder offers resolutions from 400 to 2048 ppr. Power supply options include 5 V DC, 5/28 V DC, and 8/24 V DC with reverse polarity protection. The current consumption without load is 100 mA max, and the max load current varies by output type. The max output frequency is 105 kHz, and the counting direction is A leads B clockwise.

Mechanical Specifications: The bore diameter options are 40, 50, and 60 mm. The enclosure rating is IP 54, with a max rotation speed of 3000 rpm. The encoder can withstand shocks of 50 G and vibrations of 10 G. The body, shaft, and housing materials are EN-AW 2011 aluminum, and it includes 2 ball bearings with a life of 109 revolutions. Operating temperature ranges from 0° to +60°C, and storage temperature ranges from -25° to +70°C.

Connections: The encoder provides cable outputs for different electronic interfaces, with specific color codes for each channel and power supply connection.

Resolutions: Available resolutions include 400, 800, 1000, 1024, 1440, 1600, 2000, and 2048 ppr, with preferred resolutions highlighted in bold.

Accessories: Torque arms are available in different lengths with specific ordering codes, and include M5 x 12 screws.
