Technical Insights

* NPN (Sinking): Connects the load to ground (0V) when activated Facebook.

* NO (Normally Open): Circuit closes (turns ON) only when an object is detected.

* NC (Normally Closed): Circuit opens (turns OFF) when an object is detected; often used for fail-safe safety monitoring Electro-Tech-Online Se.

* Combined (NO+NC): Typically 4-wire sensors that provide both signals for complementary logic or system redundancy.
