Product Description

The XS4P18KP340 is characterized by its physical construction and electrical output:

Principle of Operation: It uses a high-frequency electromagnetic field generated by an internal coil. When a metallic object enters this field, eddy currents are induced in the object, absorbing energy from the oscillator and causing the oscillation amplitude to decrease. This change is detected by the sensing circuit, which then changes the state of the output transistor.
Physical Construction:
- XS4: Denotes the OsiSense XS series.
- P18: Indicates a cylindrical body with a diameter of 18mm (M18 threading).
- P: Denotes a plastic (or plastic front face) housing material, making it suitable for environments where corrosion resistance or non-magnetic properties are required.
Electrical Characteristics:
- K: Indicates a flush mountable (shielded) sensor design, meaning the sensor head can be embedded in metal without interference from the surrounding material.
- 3: Indicates the switching function is NO (Normally Open)—the output is normally OFF and turns ON when metal is detected.
- 40: Denotes the electrical configuration as 3-wire DC, PNP output (Positive-Negative-Positive).

Non-Contact Detection: Eliminates wear and tear, providing a long operating life and high reliability.
Contamination Immunity: Unaffected by dust, dirt, oil, and humidity, making it reliable in harsh industrial environments.
Flush Mountable (Shielded): Allows the sensor to be safely recessed into metal machine parts without risk of false triggering from the surrounding material, saving installation space.
Standardized Output: The 3-wire DC PNP output is the industry standard for PLCs and digital inputs, ensuring easy integration with virtually all modern control systems.
Fast Response: High switching frequency allows for precise detection of rapidly moving objects.

Target Material: Ensure the target object is metallic. Non-metallic materials (plastic, wood, liquid) will not be detected.
Sensing Distance Derating: The specified nominal sensing distance ( $S_n$ ) is for mild steel (Fe 360). For other metals (e.g., aluminum, stainless steel, copper), the actual sensing distance will be significantly less. Consult the manufacturer’s reduction factors.
Minimum Target Size: The target metal object must be larger than the sensor face diameter to achieve the full sensing distance.
Interference (Spacing): When mounting multiple sensors, ensure they are separated by the minimum recommended distance (both side-by-side and face-to-face) to prevent mutual interference (cross-talk).
Load Type: Since this is a PNP output, the output wire (usually black) sources positive voltage to the load. The load must be connected between the output wire and the negative power supply line ( $0V_{DC}$ ).

The XS4P18KP340 is versatile and widely used in automated manufacturing and control:

Position Sensing: Detecting the exact position of moving mechanical parts (e.g., carriage stops, robotic arm positioning).
Counting: Used in conveyors and assembly lines to count metallic parts as they pass by.
Speed and RPM Monitoring: Detecting gear teeth or metal blades to measure rotational speed.
Limit Switching: Acting as a non-contact limit switch to confirm the end-of-travel position for cylinders or actuators.
Tool Presence Verification: Ensuring a metallic tool or fixture is correctly placed before a machine cycle starts.
