SCH32B

Product catalog summary

Mechanical Specifications
The SCH32B encoder features a housing made of aluminum, with a nickel-plated steel cap or aluminum for the flat cable option. The hollow shaft is brass, and the encoder weighs approximately 50 grams. It supports a maximum shaft speed of 6,000 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 it can handle axial and radial shaft loads up to 20 N.

Electrical Specifications
The encoder is incremental with a resolution range from 1 to 5000 pulses per revolution (ppr). It operates on a supply voltage between 4.5 Vdc and 30 Vdc, with a maximum output current of 25 mA per channel. The frequency response is up to 200 kHz, and it features two-channel quadrature output with an index and optional complementary outputs. It includes electrical protection against reverse polarity and 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 rating is IP 65, or IP 50 for the flat cable option.

Connection Options
The encoder offers various connection options, including standard and differential outputs with 5-pin or 8-pin M12 connectors. Cable options include standard and flat cables with IDC connectors.

Ordering Code
The ordering code for the SCH32B encoder includes specifications for pulses per revolution, output type, hollow shaft diameter, IP rating, cable length, and connector type. Additional options are available upon request.
