Type SCA16

Product catalog summary

Mechanical Specifications
The SCA16 encoder features a housing made of aluminum or brass, with an aluminum cap and brass shaft. It weighs approximately 15 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 can reach up to 12,000 rpm. The starting torque is less than 0.005 Nm at 25°C, and the mass moment of inertia is 0.25 gcm². The hollow shaft can handle axial and radial loads of up to 10 N.

Electrical Specifications
The encoder operates on an incremental code with a resolution of up to 5,000 pulses per revolution (ppr). It requires a supply voltage between 4.5 Vdc and 30 Vdc, with a maximum current of 35 mA without load. The output format includes two-channel quadrature with an index and optional complementary outputs. The frequency response is up to 200 kHz, and the encoder is protected against reverse polarity and output short circuits. It complies with EN61000-6-2:2005 and EN61000-6-3:2007 for electromagnetic compatibility.

Environmental Specifications
The operating temperature range is -20°C to +70°C, with a storage temperature range of -20°C to +85°C. The encoder can withstand shocks of 100 G for 11 ms and vibrations from 10-2000 Hz at 10 G. It has an enclosure rating of IP 50, with an option for IP 65.

Connection Options
The encoder can be connected via an 8-lead shielded cable or a 10-lead flat cable with an IDC connector. The standard cable length options are 0.5 m, 1 m, or 2 m.

Ordering Information
The ordering code for the SCA16 encoder includes specifications for pulses per revolution, output type, hollow shaft diameter and length, IP rating, cable length, takeout direction, and connector type. Additional options are available upon request.
