Pepperl + fuchs encoder - incremental rotary encoder

Pepperl+Fuchs encoder-incremental rotary encoder

Incremental encoders provide a fixed number of pulses per revolution, and the speed is calculated by the number of pulses measured per unit time. In order to measure the angle and position, it is usually counted from a starting reference point.

The dual-channel output encoder has two signals with a phase difference of 90 degrees. This allows the controller to determine the direction of rotation and realize the function of bidirectional position measurement.

In addition, the three-channel incremental encoder has a third signal channel (that is, the "0" channel, or the reference channel), and there is only one pulse output per revolution.

Spark protection grade and intrinsically safe rotary encoders used in hazardous areas

Pepperl+Fuchs offers two different spark protection level encoders. One is the flameproof type, and the other is the intrinsically safe type.

Absolute encoder

Intrinsically safe EEx i

If it is an intrinsically safe type, the voltage and current will have to be kept at very low standards to prevent the generation of sparks that may ignite, thus preventing the ignition factor in the explosive environment. The following equipment is designed according to the spark protection type:

Incremental encoder

ZONE 2/ZONE 22

In addition to flameproof and intrinsically safe types, Pepperl+Fuchs also provides rotary encoders that can be used in Zone 2/Zone 22.
