Chapter 5: The Response Time (The Speed)

The line restarted. The gaskets began moving. But the sensor was missing every third one. The rejects piled up.

"Too slow," the manager groaned.

Elias went back to the Specifications page of the PDF. He had forgotten about the response time.

Standard Mode: 500 µs.
High-Speed Mode: 100 µs.

The manual detailed how to change the response speed. By holding the "MODE" button and toggling the "UP" arrow, he switched the amplifier from standard stability to high-speed reaction. The trade-off, as noted in the manual, was slightly lower precision, but for detecting a gasket passing at high speed, it was the necessary sacrifice.

1. I/O Circuit Diagram (The Wiring Bible)

The LV-N11N uses a standard 4-wire configuration (Brown: +V, Blue: -V, Black: NPN Output, White: External input). However, the verified manual clarifies: Keyence LV-N11N: Quick Reference & Configuration Guide 1

Output protection circuits: How to wire a load (relay or PLC) without back EMF damage.
External input timing: The pulse width required for the "Auto Tuning" and "Laser OFF" functions.
