Schneider Electric XS4P18AB120 NSNBC01 Push Button

The Schneider Electric XS4P18AB120 inductive sensor provides 4–20 mA analog output for continuous metal-detection and position feedback in industrial automation. As part of the XS4 family, this cylindrical M18 sensor uses a PBT plastic housing and is designed for non-flush mounting with an 8 mm sensing distance. Operation is at 12–24 V DC with a 2 m cable, delivering a proportional signal for process control, distance measurement, and machine monitoring on conveyors, packaging equipment, assembly lines, and machine tools. Rated IP67, it withstands dust and water exposure in demanding environments and supports a 500 Hz switching frequency. The device is manufactured by Schneider Electric / Telemecanique Sensors and carries CE, UL, and CSA certifications. Common replacements include XS1M18AB120, XS4P30AB120, and XS9C11RPB1L01M12 for retrofit or cross-references.
