Product Overview
The Omron D4NL-4CFA-B is a safety interlock switch.
A safety interlock switch tells the control system whether a guard door is closed, and a guard-locking version goes further: it holds the guard shut until the machine has actually reached a safe state. That distinction matters on anything with stored energy or run-down time — a flywheel, a spindle, a robot cell — where a switch that merely reports the door has opened reports it too late. These are safety components, so selection follows the machine's risk assessment and required performance level, not a catalogue number alone.

An interlock reports whether the guard is open or closed. A guard-locking device also physically holds it shut, which is required when the machine takes time to stop.
