FAQ
Q1: What is the main difference between HFBR-4503Z and HFBR-4516Z?
The core difference is the termination. The HFBR-4503Z comes as a pre-terminated assembly with a fixed 2-meter cable, while the HFBR-4516Z is a field-installable connector that you assemble onto your own length of bare POF cable on-site.
Q2: Is the RMPOF1000B receptacle compatible with both HFBR-4503Z and HFBR-4516Z plugs?
Yes, absolutely. The RMPOF1000B is designed as the universal mating interface for both the HFBR-4503Z and HFBR-4516Z plugs, ensuring interoperability within the RMPOF series.
Q3: What tools are needed to install the HFBR-4516Z field-installable connector?
Installation requires a specific tool kit, such as the HFBR-4500BER or equivalent, which typically includes a fiber stripper, a crimping tool, and a cleaver to properly prepare and secure the fiber.
Q4: Are these POF connectors suitable for DeviceNet networks?
Yes, this RMPOF series is a popular and standard choice for implementing DeviceNet networks using plastic optical fiber, providing excellent EMI immunity in industrial settings.
Q5: Can I mix pre-terminated and field-installable connectors in the same system?
Yes, this is a common practice. For example, you can use an HFBR-4503Z on a device for a quick connect/disconnect and use an HFBR-4516Z on the other end of a long cable run connected to the controller.
