Product Description

The FDFN5.5-250 connectors, featuring Yellow duplex connectors with a 5.5mm pitch, provide dual-channel input/output connections for modular systems, directly interfacing with sensors, controllers, and power modules. Designed for industrial automation, these FDFN5.5-250 plug socket pairs operate at 12-48V DC and endure -40°C to +105°C, ensuring reliability in harsh environments like robotics and machinery. Their polarized design prevents misalignment, while the IP67-rated variants offer dust/water resistance. Though compact, the connectors lack integrated communication protocols, requiring external interfaces like RS-485 for data transfer. The bright yellow housing enhances visibility in low-light conditions, but they are incompatible with high-frequency applications above 100MHz. Typical use cases include motor control, conveyor systems, and energy distribution panels.
