Product catalog summary
Overview: The SH103 is a Sine-Cosine Hollow Shaft Encoder designed for precision applications. It features a size of Ø 103 mm and supports shaft bore diameters ranging from 30 to 45 mm. The encoder offers resolutions of 1024 ppr or 2048 ppr and operates on a supply voltage of either 5 VDC or 8 to 30 VDC.
Electrical Specifications: The encoder requires a supply voltage of 5 VDC or 8 to 30 VDC with a maximum current consumption of 40 mA. It features an analog line driver output circuit with a maximum pulse frequency of 100 kHz. The device includes short circuit and reverse polarity protection, and outputs sine/cosine signals at 1Vpp.
Mechanical Specifications: Constructed with an aluminum body and stainless steel shaft, the encoder supports a maximum speed of 6000 RPM. It has a mass moment of inertia of 350 · 10-6 kgm2 for a bore diameter of 38 mm and 190 · 10-6 kgm2 for 44 mm. The starting torque is greater than 0.2 Nm, with axial and radial shaft loading capacities of 60 N and 80 N, respectively. The encoder is rated for shock resistance up to 1000 m/s2 and vibration resistance up to 200 m/s2 (cable) or 100 m/s2 (plug). It is IP65 rated and operates within a temperature range of -20 °C to +70 °C, with an optional special option for +100 °C.
Ordering Code: The encoder's ordering code includes options for group function, mechanical options, output signals, basic series number, connection type, shaft size, connector location, and resolution. Special functions and designs are indicated by a code at the end of the part number.
Connection and Pinout: The encoder provides detailed pinout information for various connector types, including 12 Pin M23, 9 Pin D-Sub, and 10 Pin MIL 3102. The connection function and corresponding cable color codes are specified for each pin.
Accessories: Available accessories include mounting clips and pins, as well as mating connectors/female plugs for different pin configurations.
