Top worx TXP-M20GNEM - Explosion-Proof Magnetic Sensing - Industrial ATEX Stainless Steel - Limit Switch

The Topworx TXP-M20GNEM is a rugged, high-precision valve position sensor engineered for industrial automation systems operating in extreme environments. Featuring a corrosion-resistant 316L stainless steel housing with an IP68/IP69K-rated enclosure, this sensor withstands harsh conditions, including high-pressure washdowns, abrasive chemicals, and temperatures ranging from -40°C to +120°C.

Utilizing advanced Hall Effect sensing technology, it detects valve positions (open/closed or intermediate states) without mechanical contact, ensuring zero wear, long-term accuracy, and maintenance-free operation. Compatible with ball, butterfly, and gate valves, the TXP-M20GNEM is ideal for oil and gas, chemical processing, marine, and food-grade industries requiring robust performance in hazardous or corrosive environments.

• Output Signal: Dual NPN/PNP proximity switches (sourcing, 300 mA) with short-circuit protection.
• Supply Voltage: 10-30V DC (universal input with reverse polarity protection).
• Enclosure Rating: IP68/IP69K, NEMA 6P.
• Housing Material: 316L stainless steel with PEEK sensing face.
• Operating Temperature: -40°C to +120°C.
• Connection Type: M16x1.5 quick-disconnect connector with PUR shielded cable.
• Certifications: ATEX/IECEx (Zone 1/21), SIL 3 compliance, FDA 21 CFR 177.2600 (food-grade).
• Sensing Range: Adjustable via magnetic cam (up to 20 mm).

The TXP-M20GNEM is critical for monitoring valve positions in offshore oil and gas platforms, ensuring leak detection and safety compliance in explosive atmospheres. In chemical plants, it provides precise feedback for valves handling corrosive media like sulfuric acid or chlorine gas.

Food and beverage facilities leverage its FDA-compliant design for hygienic valve control in CIP (Clean-in-Place) systems, while marine applications rely on its saltwater-resistant construction for ballast valve monitoring. Its IP68/IP69K rating also makes it suitable for wastewater treatment plants, pharmaceutical cleanrooms, and high-pressure washdown environments requiring submersion resistance.

• Non-Contact Sensing: Hall Effect technology eliminates mechanical wear, reducing downtime and lifecycle costs.
• Extreme Durability: 316L stainless steel and PEEK materials resist corrosion, UV exposure, and chemical abrasion.
• Flexible Integration: Dual NPN/PNP outputs and M16 connector ensure compatibility with PLCs, DCS, and IoT platforms.
• Safety Compliance: ATEX/IECEx Zone 1/21 and SIL 3 certifications for ultra-hazardous environments.
• Field Adjustability: Tool-free magnetic cam enables rapid calibration for diverse valve configurations.
