The XS4P18AB120 is an M18 cylindrical, non-flush inductive proximity sensor with an all-PBT plastic housing that provides good chemical stability and insulation. This automation component supports a 12 to 24 V DC power supply, utilizes a 2-wire circuit, and outputs a 4 to 20 mA analogue current signal through its standard 2-meter integrated cable, with a nominal sensing distance of 8 mm.
Integrated reverse polarity protection prevents burnout from miswiring
Standard M18 threaded profile allows direct replacement on existing brackets
This sensor incorporates an integrated reverse polarity protection circuit to prevent component damage caused by wiring errors. During operation, its residual current (leakage current) under no-load or active states remains below 0.7 mA, ensuring the baseline linearity required for accurate signal acquisition by analogue input modules.
A high-brightness yellow light-emitting diode (LED) indicator is positioned at the rear of the sensor to provide real-time feedback on the output signal status, facilitating direct inspection and troubleshooting. Furthermore, the 2-meter, 2-wire cable features a polyvinyl chloride (PVC) outer sheath, enabling stable, long-term current signal transmission within 12 to 24 V DC low-voltage distribution systems to meet the continuous operational demands of factory automation lines, material handling conveyors, and machine tool positioning mechanisms.

Automotive Manufacturing
Continuously monitoring the stamping depth and transfer distance of sheet metal parts on car body assembly lines.
Machine Tools & Metalworking
Providing real-time feedback on micro-level displacement and feed rates of cutting tools or worktables in CNC machines.
Food & Beverage Processing
Detecting the continuous flow and accumulation height of metal cans or lids on stainless steel conveying systems.
Printing & Paper Industry
Detecting gaps between metal rollers and the homing position of metal cutting blades in large printing presses.
Metallurgy & Steel Industry
Non-contact measurement of steel plate warppage and edge positions at the output end of cold rolling or finishing lines.
Building Materials & Cement Processing
Feedback on valve opening proportions by detecting the tilt angle of metal rocker arms in powder valve control systems.
When using the XS4P18AB120, non-flush mounting clearance requirements must be strictly followed, leaving sufficient surrounding and frontal metal spacing to prevent false triggering, and the cable bending radius must exceed 4 times the cable diameter.
Electrically, ensure the DC voltage remains stable between 12 and 24 V, and connect it to a compatible 4 to 20 mA analogue controller, despite integrated reverse polarity protection, proper wiring is still required to manage residual current interference. Additionally, while the all-PBT housing provides chemical resistance, additional protective shielding should be installed if operated under high-impact conditions, extreme temperatures, or inside specific harsh chemical solvent environments.
XS4P18AB120 is an M18 non-flush 2-wire DC inductive sensor (41mm long) with PBT/PPS housing and 2m PVC cable. It operates on 12-24V DC, tracking metal objects from 0.8 to 8mm to output a 4-20mA analogue signal up to 500Hz. It has IP67 protection, works between -25°C and 70°C, and is CE, CSA, and UL certified.
It is an M18 cylindrical inductive proximity sensor manufactured by Telemecanique Sensors, designed for non-contact detection of metal objects.
What is the working principle of XS4P18AB120?
It utilizes a high-frequency oscillator to generate an alternating magnetic field at the sensing face; when a metal object approaches, the field is damped, altering the output signal.
Is XS4P18AB120 flush or non-flush mountable?
It is non-flush mountable, requiring a certain amount of non-metallic clearance around it during installation.
What is the IP rating of XS4P18AB120?
Its ingress protection rating is IP67, providing excellent dust and water resistance.
How to use XS4P18AB120 in industrial automation?
Mount it on a machine frame, connect it to a 24V DC power supply, and wire the 4-20mA analogue pin to a PLC analogue input module to monitor precise displacement or position of metal parts.
