2.5mm mono plug P-121(E) 1 piece

This is a 2.5mm diameter mono plug. The black part can be removed, so please remove it and solder it before use. Connector type: 2.5mm plug Stereo/Mono: Mono Number of poles: 2 poles Type (straight, L-type): Straight Material: Plastic Note: RoHS compliant □Insulated and non-insulated Panel-mount types such as RCA pin jacks and φ3.5 jacks are divided into "insulated type" and "non-insulated type." Insulated or non-insulated refers to whether the GND terminal of the connector comes into contact with the panel when the connector is mounted on a panel. In the case of the insulated type, the GND terminal of the connector is not connected (contacted) with the panel. The non-insulated type is electrically connected if the panel is metallic. Insulated type connectors are used when you do not want to create a "GND (ground) loop." *What is a GND loop? A loop in the wiring, specifically a loop in the GND line, is called a "GND loop." When magnetic flux intersects with the loop, a current flows in the GND line, which generates a voltage that becomes noise. In such a case, cutting the loop can prevent noise caused by magnetic flux interlinkage.
