Generic LJ30A3-15-J/EZ / R30-15A1 Inductive Proximity Sensor, AC NO, 90–250VAC, 15mm Range, IP65

This sensor is designed for AC operation with a wide input range of 90 to 250 volts AC. This makes it compatible with common industrial line voltages worldwide, such as 110VAC and 220VAC, without requiring an external power supply or converter.

Yes, inductive proximity sensors can detect all conductive metals, including non-ferrous types like aluminum, brass, and copper. However, the effective sensing distance may be reduced compared to ferrous metals like steel. Always refer to the sensor's datasheet for specific reduction factors.

A non-shielded (or unflush) sensor does not have a metal band around its sensing face. This allows it to detect objects from the side of the barrel but means it cannot be flush-mounted in metal. You must maintain a clearance around the sensor barrel when installing it near metal surfaces to prevent false triggering.

Connect the brown wire to the AC line voltage (L) and the blue wire to the neutral (N). The black wire is the switched output. In its normal state (no target present), the circuit between black and blue is open. When a metal target enters the 15mm detection zone, the switch closes, connecting the black output to the blue neutral line to complete the load circuit.
