Telemecanique XS4P18KP340 Inductive proximity switch

Product Dimensions：

The XS4P18KP340 belongs to the Telemecanique Sensors' OsiSense XS range of general-purpose inductive proximity sensors. It utilizes an oscillating magnetic field to detect the presence of metallic objects without physical contact.

• Sensor Type: Inductive Proximity Sensor.

• Design: Cylindrical, M18 threaded barrel.

• Housing Material: Durable PPS (Polyphenylene Sulfide) plastic.

• Mounting: Non-flush mountable (unshielded), meaning the sensing face must be clear of surrounding metal to achieve the specified sensing range.

• Output Versatility: It features a highly flexible 4-wire DC output, which is programmable to function as either:

• PNP (Positive-Negative-Positive) or NPN (Negative-Positive-Negative).

• NO (Normally Open) or NC (Normally Closed).

⚙️ Product Specifications (Technical Parameters)

✨ Product Advantages

• High Versatility (Universal Compatibility): The 4-wire design allows the user to select PNP or NPN and NO or NC output configurations, making it compatible with virtually any PLC or industrial controller worldwide.

• Excellent Environmental Resistance: With an IP68 rating and robust PPS plastic housing, the sensor is highly resistant to dust, water immersion, oil, chemical agents, and mechanical shock/vibration.

• High Switching Speed: A switching frequency of up to $2000 \text{ Hz}$ makes it suitable for detecting fast-moving objects, common in high-speed machinery.

• Integrated Protection: Includes built-in protection against reverse polarity, short-circuit, and overload, which increases its lifespan and system reliability.

• Visual Status Indicator: A yellow LED provides clear, visible feedback on the output status for quick setup and troubleshooting.

⚠️ Cautions (Important Notes)

1. Non-Flush Mounting: This sensor is unshielded (non-flush mountable). When installing, ensure there is an adequate clear space around the sensor barrel, especially the sensing face, as specified in the mounting instructions. Mounting it directly adjacent to or surrounded by metal will severely reduce or inhibit the $8 \text{ mm}$ sensing distance.

2. Voltage Range: Though rated for $12 \text{ to } 24 \text{ V DC}$, its operating limits are $10 \text{ to } 36 \text{ V DC}$. Always ensure the power supply is stable and within this range.

3. Wiring: The 4-wire system requires careful connection to achieve the desired PNP/NPN and NO/NC logic. Refer to the manufacturer's official wiring diagram to avoid damage or incorrect operation.

4. Metal Detection Only: As an inductive sensor, it will only detect metallic objects (ferrous and non-ferrous). It will not detect plastic, wood, liquid, or paper.
