Hall Effect Multiturn Rotary Encoder with Analog Output
Series ETA25PM
Specications are subject to change without notice
10 to 100-times longer life compared with multiturn
potentiometers
Free user programmable start and end position
(electrical angle 10° up to 72000°)
Simple user programming
Space saving bushing mounting, housing with 25mm
diameter
The Series ETA25PM offers based on the programming
interface an easy and exact adaptation to the application.
This helps reducing costs and the number of different
versions in stock.

Material shaft Stainless steel
Material housing Plastic / Bronze
Relationship between anti rotation pin and effective electrical angle in the state of delivery
Option anti rotation
pin A
If shaft attening is facing antirotation pin A then output signal is 0% FS.
Option anti rotation
pin B
If shaft attening is facing antirotation pin B then output signal is 0% FS.
The function as shown above represents the relationship between the anti-rotation pin A or B, the 0° position and the
resulting output signal in the delivery state of the sensor when the shaft is turned clockwise (CW direction of rotation). The
delivery state of the sensor is 10turns (= 3600°). Before and after the linear rising output signal for 3600° are located two
signal plateaus with each of 180°. The following example describes the output signal when the shaft is operated by 11
turns clockwise, starting at the 0° position:
1. 10 rotations of the shaft clockwise 0° to 3600°, linearly rising output signal 0% to 100% FS
2. 1/2 turn of shaft 180° (3600° to 3780°) signal plateau 100% FS
3. 1/2 turn shaft 180° (3780° to 3960°) signal plateau 0% FS
