Omron D4B-2116N – D4B-N Safety Limit Switch, Adjustable Roller Lever, 1NC/1NO Snap-Action, G1/2
The Omron D4B-2116N is a safety limit switch from Omron’s D4B-N series. It has an adjustable roller lever actuator, 1NC/1NO snap-action contacts, a metal housing and a G1/2 (PF1/2) conduit entry. It is rated IP67 and switches up to 10 A.
The D4B-N is designed for safety applications such as monitoring guard doors and machine positions. Its NC contact has a direct opening mechanism: the contact is forced open mechanically when the switch is actuated, even if it has welded, which gives a reliable safety signal. The robust metal housing suits demanding environments, and the adjustable roller lever lets the actuation point be set to suit the cam or target on the machine.
