Type SCA50

Product catalog summary

Mechanical Specifications:
The SCA50 encoder features an aluminum housing and electroplated aluminum cap, with a stainless steel shaft. It weighs approximately 140 grams, with an additional 60 grams per meter for the cable. The bearing life exceeds 1.9 x 10¹⁰ revolutions at rated load, and the maximum shaft speed is 12,000 rpm. The starting torque is less than 0.01 Nm at 25°C, and the shaft can handle axial and radial loads up to 20 N.

Electrical Specifications:
This incremental encoder offers resolutions from 1 to 12,500 pulses per revolution (ppr). It operates on a supply voltage between 4.5 Vdc and 30 Vdc, with a maximum output current of 30 mA per channel. The frequency response is up to 300 kHz. The output format includes two-channel quadrature with an index and optional complementary outputs. It features reverse polarity and output short circuit protection, and complies with EMC standards EN61000-6-2:2005 and EN61000-6-3:2007.

Environmental Specifications:
The operating and storage temperature range is -40°C to +100°C. It can withstand shocks of 100 G for 11 ms and vibrations from 10-2000 Hz at 10 G. The enclosure rating is IP65, with an IP67 option available.

Connection Options:
The encoder can be connected via cables with 8 leads for differential output or 5 leads for standard output, using twisted pairs and shielding. Connector options include 5-pin and 8-pin M12, and 9-pin and 12-pin M23 configurations.

Ordering Code:
The ordering code for the SCA50 encoder includes specifications for pulses per revolution, output type, shaft diameter and length, IP rating, cable takeout, and connector type. Various options are available, including standard and differential outputs, and different shaft sizes and lengths.
