SN04-N Inductive Proximity Sensor Switch
\nThe SN04-N is a rectangular-shaped inductive proximity sensor switch used for non-contact detection of metallic objects. Functioning as a solid-state limit switch, it emits a high-frequency electromagnetic sensing field from its front face. When a metal target enters this field, the sensor triggers its internal transistor switch without any physical contact, making it highly reliable and immune to wear.<\/p>\n
* Sensor Type: Inductive Proximity Sensor (detects ferrous and non-ferrous metals)
\n* Output Configuration: NPN Normally Open (NO) 3-wire system
