FAQ
Q1: Can this M8 4-pin cable support both Profinet and EtherCAT protocols simultaneously?
A1:Yes. The cable itself is a standard shielded twisted-pair physical layer cable. It only requires the M8 4-pin standard interface at the end of the device to support communication with both Profinet and EtherCAT protocols. The cable needs to be replaced.
Q2: What are the differences between cable types with a tethering chain and standard cables?
A2:Cable types with a tethering chain feature a PUR sheath and a specialized twisting process, allowing for a bending life of over 5 million times, making them suitable for applications involving intermittent motion such as robots and AGVs. Standard cables, on the other hand, are suitable for installations in fixed environments and are relatively cost-effective.
Q3: What is the minimum order quantity (MOQ) for customized products?
We support small batch sample production. The specific MOQ varies depending on the length, interface configuration, and material of the protective sleeve. Please contact us for a detailed quote.
