The E3XA11: The OMRON E3X-A11 is a DIN-rail-mount sensor amplifier for remote photoelectric sensing, rated IP66 so the amplifier body and cable entry tolerate washdown environments — suitable for food-and-bev or outdoor conveyor lines where hose-down is routine. It delivers a pulse-modulated red LED (660 nm) through a separate fiber-optic head, achieving a maximum sensing distance of 2 m. The 200 ms response time is adequate for object-presence detection on slower conveyor or packaging lines but not for high-speed counting. Switching is NPN open-collector, rated 35 mA continuous and 100 mA peak — sized for a PLC input or small relay, not a direct motor load. The operation mode is switch-selectable between Dark-ON, Light-ON, or SET, giving the integrator flexibility without a separate configuration tool.
