1770979 Description

Short technical summary and product information.

The Phoenix Contact 1770979 is a PTSM 0,5/ 4-2,5-V THR R44 PCB terminal block designed for wire-to-board connections. It features 4 positions with a 2.5 mm pitch and a screwless spring cage (tension clamp) termination for fast and reliable wire installation. The mating orientation is vertical with the board, making it suitable for top-entry applications.

 

This terminal block is rated for a nominal current of 6 A and a nominal voltage of 63 V, with a rated surge voltage of 2.5 kV. It accepts solid conductors from 0.14 to 0.5 mm² and stranded conductors from 0.2 to 0.5 mm². The stripping length is 6 mm. The housing is made of LCP (Liquid Crystal Polymer) with a UL 94 V0 flammability rating.

 

The component is designed for through-hole (THR) assembly and has pin dimensions of 0.3 x 0.8 mm with a hole diameter of 1.2 mm. The overall length is 5 mm, and each piece weighs approximately 0.00272 kg. It is packaged in quantities of 310 pieces.
