24 V AC control supply aligns with standard control panels, reducing wiring complexity and commissioning time. This simplifies PLC or PLC/HMI integration and minimizes control-supply mismatches in new builds or retrofits. Business impact: faster setup, lower risk of wiring errors, and improved reliability across process lines. Application: control with pumps, valves, or alarms in tanks and processing vessels. The unit provides one normally open contact, enabling direct control of actuators and reducing interface hardware costs. This design lowers assembly time and simplifies diagnostics. Measured capacity of 0–100 kΩ supports a broad range of conductive liquids, delivering consistent trip points and reducing recalibration needs. Application: level sensing in water/wastewater, chemical processing, and food/beverage lines. With two electrodes, the sensing is robust across tank geometries, helping prevent false overflow signals in noisy environments. Installation is straightforward with screw terminals and TH35 DIN-rail mounting options, which keeps panel space and wiring tidy. Compatibility with DIN rails TH35-15 or TH35-7.5 enables quick integration into existing control cabinets. IP50 housing protects electronics from dust and incidental contact, while standardized safety and performance approvals (UL 508, CE) help ensure compliance. The device supports a wide operating temperature range, enabling deployment across diverse sites, from low-temperature facilities to high-heat production lines. These features drive improved uptime, safer operations, and clearer maintenance planning in demanding industrial environments.

FAQs
The CM-ENE MAX mounts on TH35 DIN rails (TH35-15 or TH35-7.5). It uses screw terminals for wiring, supporting ferrule or flexible conductors (2x 0.75 ... 1.5 mm²) and rigid 2x 0.75 ... 1.5 mm². For ease of installation, ensure proper stripping length (10 mm) and secure torque (0.6–0.8 N·m). This reduces commissioning time, improves reliability, and simplifies future maintenance.
Key specs include a rated control supply of 24 V AC, output of 1 NO contact, measuring range 0–100 kΩ, and two electrodes. The unit supports AC-12 operation up to 4 A at 230 V, with a 4 kV impulse withstand and 250 V insulation between circuits. These specs enable safe, compatible integration with standard PLCs and control circuits.
Yes. The CM-ENE MAX is designed for conductive liquid level sensing and overflow protection in tanks and vessels. Its fixed 0–100 kΩ sensitivity provides repeatable trip points across typical conductive fluids, while the IP50 housing and CE/UL 508 certifications help ensure safe operation in harsh industrial environments.
The device carries CE marking and UL 508 certification, with additional UL/CSA considerations and CAN/CSA C22.2 No.14. It conforms to IEC/EN 61000-6-2 and IEC/EN 61000-6-3 for EMC robustness, and is supported by CCC and UKCA declarations. These certifications help ensure regulatory compliance across global installations.
Installation simplicity, robust protection against overflow, and predictable behavior reduce downtime and maintenance time. The screw-terminal design, DIN-rail compatibility, and fixed sensitivity minimize recalibration frequency, while CE/UL compliance reduces regulatory risk. The result is lower total cost of ownership through fewer unscheduled interventions and faster diagnostics.
