- skybrian 7y agoWhat are locking headers?
- nlfwhulsdhouv 7y agoA 'header' is a board-to-board or wire-to-board connector: https://www.digikey.com/product-detail/en/w-rth-elektronik/61300411121/732-5317-ND/4846827 https://www.digikey.com/product-detail/en/w-rth-elektronik/6... This is the type of connector most commonly used in hobby electronics, such as on the Arduino and Raspberry Pi. 0.1" is the 'pitch', the distance between pins. I picked a 1x4 (meaning <rows> x <pins> or <rows> x <pins per row>) version, but they come in many different pin and row counts. The version above is very simple, just bare pins that would get soldered to a PCB. There are many that come with additional 'features' that could be useful. For instance, you could get a locking header that has a tab to retain the connection against vibration or tugging. Or you can get a key or shroud that forces the connector to be inserted in the correct orientation. They also come in versions that support soldering directly to a PCB, vertically or at a right angle, or connecting to wires directly. Here is a locking header: https://www.digikey.com/product-detail/en/molex/0022232041/WM4202-ND/26671 https://www.digikey.com/product-detail/en/molex/0022232041/W... If you scroll down to 'mating products' you can find wire-to-board connectors designed to mate with it.
