The Omron D4F3203R is a limit switch with a roller lever actuator, offering 2 normally-open and 2 normally-closed slow-action contacts. The slow-action (snap-action) contact design ensures positive break, meaning the contacts change state independently of the actuator speed — critical for reliable switching in vibration-prone or slow-moving cam applications. Rated for 750 mA at 240 VAC and 270 mA at 250 VDC, so it handles standard control-circuit loads but not motor or solenoid inrush directly; use an interposing relay for higher currents.
The 3 m cable termination saves panel wiring time — no separate connector to source, just strip and land. Insulation voltage rated at 500 VDC, so the switch can be used in circuits with higher common-mode voltage than the switching voltage alone suggests. The 2NO/2NC configuration gives you one set for the safety circuit and one for the PLC input, or dual-channel monitoring without an extra switch.
