The slow-action contact block provides a 1NO/1NC configuration, switching up to 2 A AC at 400 V or 400 mA DC at 250 V. The 9.4 N operating force gives a positive snap-over feel, and the IP67 rating means the switch body and actuator seal against dust ingress and temporary immersion — suitable for washdown zones on food processing or packaging lines where hose-down cleaning is routine. ## Mounting and wiring considerations Screw terminals accept stranded or solid conductors; the metal housing provides mechanical robustness for high-vibration environments such as conveyor transfer points or machine tool guards. The adjustable roller lever allows the actuator arm to be repositioned to suit cam profiles or door travel arcs — a practical feature when retrofitting into existing guard interlock positions where the actuation angle is not perfectly aligned.","metaTitle":"D4B4516N Limit Switch, Adjustable Roller Lever, IP67, 1NO/1N","metaDescription":"D4B4516N limit switch from Series D4B.
