Output type and wiring
The E3S-CT11-L 2M: The output is rated at 100 mA — that's the maximum load it can switch directly. If you're driving a PLC input or a small relay, that's plenty. For a contactor coil or a valve solenoid, you'll need an interposing relay. The "L" in the part number typically indicates a light-ON mode — the output turns on when the sensor sees the light beam. The "2M" suffix means it comes with a 2-meter cable pre-attached, so you don't need to order a separate connector.
