Weidmüller BLF 5.08HC/03/180 SN OR BX SO PCB Plug-in Connector, 3-Pole, 5.08mm Pitch, PUSH IN, Orange, 17.5A, 400V

Industrial control panel builders and machine OEMs often need a reliable, tool-free connection for PCB-level signal and power wiring. The Weidmüller BLF 5.08HC/03/180 SN OR BX SO is a 3-pole female plug with a 5.08 mm pitch, designed for straight (180°) conductor entry. Its PUSH IN spring connection accepts solid and flexible conductors from 0.2 to 2.5 mm², making field wiring quick and secure without special tools. The orange PBT housing provides high visibility and meets UL 94 V-0 flammability standards, while the tinned copper alloy contacts ensure long-term corrosion resistance.
