The IB18 Series High-Temperature and ATEX-Certified Inductive Proximity Sensor (Part Number: IB18C339) developed and manufactured by premium German sensor specialist ipf electronic gmbh provides an advanced metallic target detection solution for severe industrial automation. It combines continuous thermal endurance across -25°C to +180°C with ATEX Zone 22 combustible dust safety certification, featuring a PNP Normally Open (NO) switching output logic for standard target-present detection applications.

PRODUCT SPECIFICATIONS & FEATURES (PART NO: IB18C339):
- Part Number: IB18C339
- Manufacturer: ipf electronic gmbh (Germany)
- Sensor Category: High-Temperature & ATEX Zone 22 Inductive Proximity Sensor
- Mechanical Dimensions: Standard metric M18 x 1 mm thread with an overall body length of 70 mm.
- Mounting Style: Flush mountable (Shielded) configuration, allowing embedded installation flush into metallic machine brackets without side-sensing false triggers.
- Nominal Sensing Range (Sn): 5 mm, delivering high precision and dependable repeat accuracy.
- Switching Output: PNP Normally Open (PNP NO), switching active-high when a metallic target enters the sensing zone, handling load currents up to 150 mA.
- Wide Supply Voltage Range: 10 – 35 V DC, fully protected with integrated short-circuit and reverse polarity safeguards.
- Integral Connection Lead: 5-meter (5m) high-grade PTFE cable providing outstanding resistance against extreme heat, industrial oils, aggressive chemicals, and mechanical bending fatigue.
- Enclosure Construction: Precision machined from premium Stainless Steel 1.4305 (AISI 303 / V2A) for superior mechanical robustness and resistance to high-temperature oxidation.

KEY HIGHLIGHTS:
- Self-Contained High-Temperature Electronics: Integrates evaluation circuitry directly inside the sensor housing without requiring a separate external amplifier, enabling direct interfacing to PLCs, digital counters, and industrial controllers.
- Certified for ATEX Zone 22 Dust Environments: Certified safe against surface thermal ignition and electrical sparking in potentially explosive combustible dust atmospheres (grain, wood, flour, polymer dusts).
- Integral 5m PTFE High-Temperature Lead: Eliminates vulnerable electrical connector joints within hot machine zones, allowing uninterrupted signal routing straight to outside terminal boxes.
