These 33mm (1.3") spring loaded pogo pins are great for programming and applications where you don't always want headers soldered onto your boards. We use them for our programming jigs in production. The pins fit snugly into most standard perf board holes. Solder them just like you would normal wire. Dimensions: * Length: 1.3" (33mm) * Travel: 1/4" (6.5mm) * Head size 0.06" (1.5mm) Documents: * Dimensional Drawing (PP4) https://elecena.pl/product/1202664/pogo-pin-w-concave-tip 2010-11-02 https://elecena.pl/product/1202664/pogo-pin-w-concave-tip 2016-11-25 https://elecena.pl/product/1202664/pogo-pin-w-concave-tip 2016-11-28 https://elecena.pl/product/1202664/pogo-pin-w-concave-tip 2016-11-29 https://elecena.pl/product/1202664/pogo-pin-w-concave-tip 2016-12-09 https://elecena.pl/product/1202664/pogo-pin-w-concave-tip 2016-12-13 https://elecena.pl/product/1202664/pogo-pin-w-concave-tip 2016-12-26 https://elecena.pl/product/1202664/pogo-pin-w-concave-tip 2017-01-10 https://elecena.pl/product/1202664/pogo-pin-w-concave-tip 2017-11-24 https://elecena.pl/product/1202664/pogo-pin-w-concave-tip 2017-11-28 https://elecena.pl/product/1202664/pogo-pin-w-concave-tip 2018-05-05 https://elecena.pl/product/1202664/pogo-pin-w-concave-tip 2018-11-21 https://elecena.pl/product/1202664/pogo-pin-w-concave-tip 2018-11-27 https://elecena.pl/product/1202664/pogo-pin-w-concave-tip 2022-02-22 https://elecena.pl/product/1202664/pogo-pin-w-concave-tip 2025-04-11 https://elecena.pl/product/1202664/pogo-pin-w-concave-tip 2025-04-14 https://elecena.pl/product/1202664/pogo-pin-w-concave-tip 2025-05-21 https://elecena.pl/product/1202664/pogo-pin-w-concave-tip 2025-05-23
