The 3040630, also known as Latching-PR/2, is a latching accessory used to secure plug-in connectors. This component is orange, has 2 positions, and is constructed from PA-GF material. It is designed to be snapped onto the outside of a plug housing, where it then hooks onto the terminal block housing to create a secure, latched connection. This mechanism ensures a reliable connection for all compatible plug versions, preventing accidental disconnection.
