Product catalog summary

Overview: The SH120 is a Sine-Cosine Hollow Shaft Encoder designed for precision applications. It features a size of Ø 120 mm and supports shaft bore diameters ranging from 40 to 65 mm. The encoder offers resolutions of 1024 ppr or 2048 ppr and operates with a supply voltage of either 5 VDC or 8 to 30 VDC.

Electrical Specifications: The encoder requires a supply voltage of 5 VDC or 8-30 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 for each channel, and outputs sine/cosine signals at 1VPP.

Mechanical Specifications: Constructed from aluminum or stainless steel, the encoder can operate at speeds up to 4000 RPM. It has a mass moment of inertia of 220 · 10^-6 kgm² for a bore diameter of 50 mm and 215 · 10^-6 kgm² for 65 mm. The starting torque is greater than 0.2 Nm, with axial and radial shaft loading capacities of 60 N and 80 N, respectively. It is rated for shock resistance up to 1000 m/s² and vibration resistance up to 200 m/s² (cable) or 100 m/s² (plug). The protection class is IP65, and it 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 a detailed pinout for both 12 Pin M23 and 9 Pin D-Sub connectors, with corresponding cable color codes for each function (GND, Vcc, A, B, Z, A\, B\, Z\).

Accessories: Available accessories include torque arms of various lengths, tethers, mounting clips, and pins. Mating connectors and power joint sets are also available for the encoder series 120.
