Function
The cuboid housing of this incremental rotary encoder is suitable for easy fastening onto mounting profiles or comparable types of construction. Four through holes and two grooves in the housing allow a wide range of installation possibilities. The diecast zinc housing gives the incremental rotary encoder the sturdiness it needs.
The pulse disk is designed in plastic up to 600 pulses. Beyond that, glass is used.
