Product catalog summary

Overview: The SS581 is a Sine-Cosine Solid Shaft Encoder designed for industrial applications. It features a standard size of Ø 58 mm with synchro flange mounting and supports shaft diameters ranging from 6 to 12 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 Sin/Cos signals at 1Vpp.

Mechanical Specifications: The body and cover are made of aluminum, while the shaft is stainless steel. It supports a maximum speed of 6000 RPM and has a mass moment of inertia of ≤ 2.5 · 10^-6 kgm². The starting torque at 25°C is > 0.05 Nm, with axial and radial shaft loading limits of 40 N and 30 N, respectively. The encoder is rated for shock resistance up to 2000 m/s² and vibration resistance up to 300 m/s² (cable) or 150 m/s² (plug). It has an IP65 protection class and operates within a temperature range of -20 °C to +70 °C, with an optional extension to +100 °C.

Ordering Code: The ordering code includes options for mechanical features, output signals, connection types, shaft sizes, connector locations, and resolutions. Special functions and designs are available upon request.

Connection Details: The encoder uses a 12 Pin M23 connector with specific pin assignments for functions such as GND, Vcc, and output signals (A, B, Z, A\, B\, Z\). A color code is provided for cable connections.

Accessories: A range of accessories is available, including measuring wheels, couplings, mounting brackets, clamping claws, mating connectors, and spring-loaded arms. These accessories are compatible with various encoder series, including 580, 581, 700, and 900.
