SCA24-IP65

Product catalog summary

Mechanical Specifications:
The SCA24 IP65 encoder features a brass housing and electroplated steel cap, with an option for aluminum for flat cable configurations. The shaft is made of stainless steel. The encoder weighs approximately 35 grams, with the cable adding 50 grams per meter. It supports a shaft speed of up to 12,000 rpm and has a bearing life exceeding 1.9 x 10¹⁰ revolutions at rated load. The starting torque is less than 0.005 Nm at 25°C, and the shaft can handle axial and radial loads of up to 20 N.

Electrical Specifications:
The encoder operates on a supply voltage ranging from 4.5 Vdc to 30 Vdc, with a maximum current of 35 mA under no load. It provides incremental output with resolutions from 1 to 7500 pulses per revolution (ppr). The output format includes two-channel quadrature with an index and optional complementary outputs. The encoder is protected against reverse polarity and output short circuits, and it meets EMC standards EN61000-6-2:2005 and EN61000-6-3:2007.

Environmental Specifications:
The operating and storage temperature range is -40°C to +85°C. It can withstand shocks of 100 G for 11 ms and vibrations from 10-2000 Hz at 10 G. The enclosure is rated IP65, suitable for industrial environments.

Connection Options:
The encoder offers various cable options, including 8-lead differential and 5-lead standard twisted pairs, both shielded. A flat cable option with an IDC connector is also available.

Output Terminations:
Standard and differential outputs are available, with specific wire color codes for each channel. The encoder supports M9 connectors with 5 or 8 pins.

Ordering Code:
The ordering code includes specifications for pulses per revolution, output type, shaft diameter and length, IP rating, cable length, and connector type. Custom options are available upon request, particularly for wind power applications.
