Install on TH35-15 or TH35-7.5 DIN rails for secure mounting; use screw terminals with flexible ferrule sizes from 0.5 to 2.5 mm² or rigid 0.5 to 4 mm² as listed. Tightening torque for the main circuit is 1 N·m, while control circuit requires 0.9 N·m. Wire stripping length is 8 mm for main circuit and 10 mm for the main connections. Mounting positions range from 1 to 6, and ensure proper enclosure sealing to maintain IP50 protection.
Key specs include a measuring range of 5 to 100 kΩ, rated control supply voltage of 24 to 240 V AC/DC, and a 1 c/o SPDT output (250 V, 4 A). It supports 50/60 Hz supply, has IP50 housing with terminals IP20, and offers operating temperatures from -25 to +60 °C. The device is designed for AC-12 durability up to 100,000 cycles and mechanical durability of 1,000,000 cycles, with appropriate insulation voltages across circuits.
Yes. The CM-ENS.11S uses open-circuit principle sensing to detect the presence or absence of conductive liquid, triggering the SPDT output to stop or alarm a pump as needed. With adjustable sensitivity (5–100 kΩ) via front-face potentiometers, you can tailor the trip point to specific liquid properties and pump behavior, reducing false trips and protecting equipment from dry running.
The CM-ENS.11S carries CE and UKCA marks, with UL/CSA compatibility for safety-critical control circuits. It is listed under can/csa standards and complies with IEC/EN 61000-6-2 and 61000-6-3 for EMI immunity and emissions, UL 508 for industrial controls, and RoHS/REACH. Additional declarations include CCC and DNV GL certifications for certain markets, ensuring compliance across global installations.
The device offers long mechanical durability (1,000,000 cycles) and electrical durability (100,000 cycles), reducing replacement and maintenance costs in high-usage environments. Its front-face sensitivity adjustment and accessible screw-terminals simplify calibration and diagnostics, lowering commissioning time. Accessories for electrodes and protective covers help maintain regulator settings, supporting lower downtime and improved process reliability over the asset lifetime.
