Type SCH16G

Product catalog summary

Mechanical Specifications
The SCH16G encoder features a housing made of aluminum or brass, with an aluminum cap and a brass hollow shaft. It weighs approximately 12 grams, with the cable adding 50 grams per meter. The bearing life exceeds 1.9 x 10¹⁰ revolutions at rated load, and the shaft speed is capped at 5,000 rpm. The starting torque is less than 0.005 Nm at 25°C, and the hollow shaft can handle axial and radial loads up to 10 N.

Electrical Specifications
This incremental encoder offers resolutions from 100 to 5,000 pulses per revolution (ppr) and operates on a supply voltage between 4.5 Vdc and 30 Vdc. The output format includes two-channel quadrature with an index and optional complementary outputs. It supports a frequency response up to 200 kHz and provides electrical protection against reverse polarity and short circuits.

Environmental Specifications
The operating temperature range is -20°C to +70°C, with storage temperatures from -20°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 has an IP 50 rating, suitable for industrial environments.

Connection Options
The encoder can be connected via an 8-lead shielded cable or a 10-lead flat cable with an IDC connector. It supports differential and inverted outputs, with specific wire color coding for each channel.

Ordering Information
The ordering code for the SCH16G includes specifications for pulses per revolution, output type, hollow shaft dimensions, IP rating, cable length, and connector type. Additional options are available upon request from Scancon A/S.
