D4N Safety Limit Switch, Top Roller Plunger D4N-4132
OMRON — D4N Series
Plunger-actuated variant of Omron's D4N safety-compatible limit switch, using the same 22 x 47 mm plastic housing platform but fitted with a spring-return top roller plunger for linear (push) actuation instead of a rotary lever. Suited to cam or dog-operated linear position detection where a lever swing radius is not available. Shares the D4N family's direct-opening mechanism and full safety-standard conformance.
