Buy Rexroth HED series pressure switch | Partsdic®

Design and Construction: The Rexroth HED series pressure switch is constructed with high-quality materials to ensure durability and reliability in demanding industrial environments.

It typically features a robust housing made of metal or stainless steel, offering protection against corrosion and external influences. This design ensures a long service life and dependable operation.

Pressure Range: One of the most critical specifications of the HED series pressure switch is its pressure range. These switches are available in various pressure ranges, allowing users to select the model that best suits their application's requirements. Pressure ranges can typically vary from low-pressure settings of a few bar (e.g., 0-10 bar) to high-pressure settings (e.g., 0-400 bar) or even higher, depending on the specific model chosen.

Switching Function: The Rexroth HED series pressure switch is available in both normally open (NO) and normally closed (NC) configurations. This means it can either open or close an electrical circuit when the pressure crosses a predetermined setpoint. This switching function is crucial for controlling various hydraulic and pneumatic processes, such as starting or stopping a hydraulic pump or activating an alarm when pressure reaches a critical level.

Adjustability: These pressure switches are designed to be adjustable, allowing users to set the desired pressure setpoint within the specified range. Adjustability is often achieved through a set screw or dial, which provides precision in configuring the switch for the specific pressure requirements of the application.

Accuracy and Repeatability: Rexroth HED series pressure switches are known for their high accuracy and repeatability.

This ensures that the switch consistently responds to pressure changes within tight tolerances, contributing to the reliability and consistency of the controlled system.

Electrical Ratings: The electrical ratings of these pressure switches are an essential specification to consider. They typically include parameters such as maximum voltage and current ratings, ensuring compatibility with the electrical components of the system in which they are installed.

Environmental Protection: Many models within the HED series come with IP (Ingress Protection) ratings that indicate their resistance to dust and water ingress. These ratings are crucial when the pressure switch is used in environments with exposure to moisture, dust, or other contaminants.

Connections: The pressure switch features standard thread or flange connections for easy installation into hydraulic or pneumatic systems. The choice of connection type depends on the specific requirements of the application and the system's design.
