The 25.173.0253.0 is a PCB-mounted terminal block connector designed for horizontal wire-to-board connections with a 5.08 mm pole spacing. It features a 2-pole configuration with an overall length (G) of 11.01 mm and a terminal pitch (T) of 5.08 mm. The connector is rated for 300 V according to VDE 0110, UL, and CSA standards, with a current rating of 6.5 A for wire gauges No. 22–12 AWG. The housing is constructed from PA 66/6 gray material (UL 94-V0), with a nickel-plated brass clamping body and tin-plated E-copper contact clips. The connector includes an M3 clamping screw made of zinc-plated steel and features a solder pin of 0.9 × 0.9 mm with a bore hole diameter of 1.3 mm. This terminal block is commonly used in industrial control systems, power distribution panels, and general-purpose PCB interconnect applications where reliable, compact connections are required.
