Hengstler AC58/1213EF.47SGB absolute rotary encoders

Hengstler AC58/1213EF.47SGB is an absolute rotary encoder under Hengstler, which is often used in the field of industrial automation and can accurately measure the rotation angle and position. The following is an introduction to its possible related parameters and features:

Electrical parameters:

Working voltage: usually 10 - 30Vdc, the power supply must be within this range, and isolation must be done to prevent impact from 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, a pair of clock triggers, and a pair of data outputs.

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 achieve fast and accurate position feedback.

Rotation direction signal: It has a rotation direction signal pin DIR. When the level is low, the default is clockwise data increase facing the shaft. When the working power is high, the direction changes to counterclockwise data increase.

Zero-point positioning signal: There is a zero-point positioning pin MID P. When it contacts the high level, the current position data output is the zero-degree position. When it works normally, it 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 6/8/10mm shaft diameter, 20mm shaft length; blind hole type, 8-15mm hole diameter, 20mm hole depth may also be provided.

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 IP65, which is waterproof and dustproof, but do not immerse the shaft 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. The encoder is a precision instrument. Avoid knocking, collision or falling during use, especially pay attention to the protection of the shaft end.
