The Grace Technologies P-R33-F3R3-M3 is a panel interface connector designed for industrial control applications. It provides external access to programmable logic controllers and other devices through a closed enclosure door, enhancing operational safety. The unit features an RJ45 Ethernet port and a DB9 serial port configuration, allowing for secure programming and data exchange without exposing internal components. Constructed with durable materials, it supports standard mounting configurations for integration into control panels.
Verify the specific pinout configuration and cable requirements against the system design before procurement. Confirm that the mounting hole dimensions align with the existing panel structure. Ensure the selected model matches the required environmental protection rating for the intended installation location. Cross-reference the connector type with the connected device's input specifications to guarantee compatibility.
Select this component when secure, external access to internal control hardware is required without compromising panel integrity. Consider the available port types and their respective utility for the specific control application. Evaluate the mechanical fit within the designated panel space. Assess the need for additional protective covers or locking mechanisms based on the operational environment and security requirements.
This part belongs to the GracePort series of panel interface connectors manufactured by Grace Engineered Products. These connectors are engineered to improve safety and compliance in industrial settings by eliminating the need to open panel doors for maintenance or programming. The series offers various combinations of ports and enclosures tailored to different control system needs.
Public confirmed substitute part numbers: P-R2-K3RF0-U543, P-B10-M3RF0.
