Characteristics:
The SCH24AB is a hollow shaft absolute singleturn encoder utilizing magnetic resistance technology. It features strong compact electronics and is designed for direct connection to PLCs. The encoder operates with a supply range of 5V ± 10% or 3.3V ± 10% and is built with a robust construction suitable for industrial environments, supported by two precision ball bearings. The standard IP rating is IP 64, with an option for IP 50 when using a ribbon cable and IDC-Connector.

Electrical Specifications:
The encoder operates at a maximum current of 25mA with short circuit protection. It supports operating temperatures from -40°C to +100°C and storage temperatures from -55°C to +100°C. The resolution options include 10-bit and 12-bit, with different permissible speeds depending on the mode (slow or fast). The system propagation delay varies from 65 µs to 384 µs depending on the resolution and mode.

Mechanical Specifications:
The encoder weighs approximately 75g and is constructed from electroplated steel, brass, and stainless steel. It supports hollow shaft dimensions ranging from ø2mm to ø1/4” and can handle axial and radial loads up to 20N. The mechanical maximum speed is 10,000 rev./min, and the start torque is less than 0.005 Nm at 25°C.

Serial SSI-Interface:
The SSI interface includes a timetable for data output, with specific timing requirements for CLK, DO, and CSn signals. The angular position data is represented by bits D11 to D0, with additional status bits for offset compensation, cordic overflow, linearity alarm, and magnetic field changes.

Ordering Codes:
The document provides detailed ordering codes for different configurations, including resolution, hollow shaft dimensions, IP rating, cable length, and type. Options for ribbon cable lengths and IDC connectors are also specified.
