Rexroth speed sensor HDD1/HDD2 R902602512 R902602515 A6VM/E A2FM

1. Product Overview

This product isRexrothoriginal or highly compatible alternativespeed sensor, belonging toHDD1 / HDD2 series. This sensor is specifically designed for harsh hydraulic environments and is mainly used for real - time monitoring ofA6VMorA2FMand other hydraulic motors' rotational speed and direction, and feeds back the signals to the controller (such as PLC or frequency converter) to achieve closed - loop control or overload protection.

2. Core Features

• High reliability and durability: Specifically designed for harsh working conditions in hydraulic systems, such as high vibration, oil contamination, and electromagnetic interference. It has a high - level shell protection grade and can operate stably for a long time.

  
  

• Accurate signal feedback: By sensing the toothed ring or magnetic ring installed on the motor shaft, it outputs stable pulse signals (usually PNP or NPN square waves). The frequency is strictly proportional to the motor's rotational speed, with high accuracy.

  
  

• Strong compatibility: ModelsR902602512andR902602515are common specifications in the Rexroth HDD series. They are fully compatible with the installation interfaces (such as thread size and mounting hole positions) and electrical characteristics of motors like A6VM and A2FM, and can be directly replaced.

  
  

• Key safety functions: It is an essential component for realizing advanced functions such as “overspeed protection”, “stall alarm”, “synchronous control” to prevent equipment damage caused by motor out - of - control.
