Hengstler AC58/1212EK.72MCR3 absolute rotary encoder is a sensor launched by Hengstler for accurate measurement of rotational position and angle, and is commonly used in the field of industrial automation. The following are some of its possible features and technical parameters:
Electrical parameters:
Working voltage: usually 10 - 30Vdc, the power supply must be stable and well isolated to prevent the impact of large starting appliances in the power grid.
Output signal: The international standard SSI signal format may be adopted, and high-resolution feedback is achieved through RS422. Clock/Data is a four-wire RS422 mode, ±5V, including a pair of clock trigger lines and a pair of data output lines.
Clock frequency: The clock frequency can reach up to 10MHz at the fastest, and the data refresh rate of the position data is ≤4μs, which can quickly and accurately feedback the position information.
Rotation direction signal: There is a rotation direction signal pin DIR. When the level is low, the default is to face the shaft clockwise data increase. When the working power supply is high, the rotation direction becomes counterclockwise data increase.
Zero-point positioning signal: It has a zero-point positioning pin MID P. When it contacts a high level, the current position data output is the zero-degree position. When it works normally, this pin is connected to the power supply 0V.
Mechanical parameters:
Dimensions: Generally 60mm outer diameter.
Shaft diameter and shaft length: There may be multiple options, such as 6mm, 8mm or 10mm shaft diameter, shaft length 20mm; blind hole type may also be provided, hole diameter 8-15mm optional, hole depth 20mm.
Connection method: You can choose clamping synchronous flange or blind hole type/semi-through hole flange, support cable output or plug output, and axial output is optional.
Protection level: The protection level is usually IP65, which is waterproof and dustproof, but the shaft should be avoided from immersion in water.
Other features: Absolute encoding method, each position has a unique code, and the current position can be known without returning to zero after power failure and restart.
