Top worx TXP-M2CGNEM - Explosion-Proof Magnetic Sensing - Industrial ATEX

Product Specification

​1. Product Overview: Topworx TXP-M2CGNEM Non-Contact Valve Position Sensor

​
The Topworx TXP-M2CGNEM is a high-performance, non-contact valve position sensor designed for industrial automation systems operating in extreme and hazardous environments. Built with a corrosion-resistant 316L stainless steel housing (IP68/IP69K-rated), this sensor delivers reliable performance under 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-M2CGNEM is ideal for oil and gas, chemical processing, marine, and food-grade industries demanding robust and precise valve monitoring.

​2. Key Technical Specifications​

• ​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: M12x1 quick-disconnect connector with PUR shielded cable.
• ​Certifications: ATEX/IECEx (Zone 1/21), SIL 2 compliance, FDA 21 CFR 177.2600 (food-grade).
• ​Sensing Range: Adjustable via magnetic cam (up to 15 mm).

​3. Industrial Applications and Use Cases

​
The TXP-M2CGNEM is extensively deployed in offshore oil rigs to monitor subsea valve positions in explosive atmospheres, ensuring leak detection and safety compliance. In chemical plants, it provides critical feedback for valves handling corrosive media such as hydrochloric acid or chlorine gas. Food and beverage facilities utilize 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 pharmaceutical cleanrooms, wastewater treatment plants, and high-pressure washdown environments requiring submersion resistance.

​4. Competitive Advantages and Unique Features​

• ​Non-Contact Sensing: Hall Effect technology eliminates mechanical wear, reducing downtime and maintenance costs.
• ​Extreme Durability: 316L stainless steel and PEEK materials resist corrosion, UV radiation, and chemical abrasion.
• ​Flexible Integration: Dual NPN/PNP outputs and M12 connector ensure compatibility with PLCs, DCS, and IoT platforms.
• ​Safety Compliance: ATEX/IECEx Zone 1/21 and SIL 2 certifications for hazardous area deployments.
• ​Field Adjustability: Tool-free magnetic cam enables rapid calibration for diverse valve configurations.

​5. Functional Capabilities and Operational Benefits

​
The TXP-M2CGNEM delivers real-time valve position feedback to control systems, triggering automated shutdowns or alarms during operational anomalies. Its dual outputs support redundant safety loops, critical for blowout preventers (BOPs) in oil drilling and high-risk chemical processes. The IP68/IP69K rating ensures reliability in submerged or high-pressure washdown scenarios, minimizing unplanned downtime. With optional IO-Link compatibility, it enables predictive maintenance by transmitting diagnostic data such as temperature thresholds and signal stability. The PUR shielded cable resists oils and solvents, while the FDA-compliant design meets stringent hygiene standards. These features make the TXP-M2CGNEM a future-proof solution for Industry 4.0 automation.
