KEYENCE PX-H72 Heavy-Duty Thrubeam Sensor Head
The PX-H72 is a high-performance M12 thrubeam sensor head from Keyence’s PX series, specifically engineered for the most demanding industrial environments. Featuring a «vacuum-packed» structure, this sensor head is completely backfilled with transparent epoxy resin to eliminate internal voids, ensuring maximum resistance to liquid penetration and mechanical shock. Its high-power infrared light source is capable of penetrating oil, dust, and dirt, providing reliable detection where standard sensors fail.

Engineered for Extreme Industrial Durability
The PX-H72 is designed to survive in conditions that typically destroy photoelectric sensors. The SUS303 stainless steel housing features a 1.9 mm thick wall to prevent damage from collisions with workpieces or over-torquing during installation.
-
Environmental Resistance: The IP68g and IP69K ratings guarantee complete protection against high-pressure water jets and continuous submersion in oil or water.
-
High Power Output: When paired with a PX-series amplifier, the «MEGA mode» provides enough power to detect objects through heavy accumulation of grease, coolant, or airborne contaminants.
-
Vibration and Shock Proof: Tested to withstand 2 hours of vibration (10 to 55 Hz) in X, Y, and Z directions, making it ideal for high-vibration machinery.
Primary Applications and System Integration
The KEYENCE PX-H72 is the industry standard for robust presence detection in:
-
Metalworking: Detecting parts inside machining centers where coolants and metal chips are present.
-
Food and Beverage: Reliable operation during high-pressure washdown cycles.
-
Material Handling: Long-range detection in large-scale automated warehouses.
-
Compatible Amplifiers: Designed for use with Keyence PX-10, PX-10P, or PX-10C series digital amplifiers for maximum sensitivity and control.
