Using range

This factory production LJK feedback sensor applied in electric power, petroleum, chemical industry, metallurgy, and other enterprises in the chemical water treatment system, ash slag system, ph measurement system, the condensate system, lime water system in various domestic and imported equipment of the feedback signal, boiler ash, ignition, electric door, suction, exhaust, the update products and other kinds of travel switch, provide location monitoring shows that.

The performance characteristics of

(1) this product adopts SMT assembly technology to conduct secondary assembly of various micro components. The contact points have no magnetization, wear and fatigue resistance.

(2) the signal is non-contact action without mechanical fault.Submersible, double-layer fully sealed structure, no oxidation, moisture-proof, water-proof, acid-base corrosion resistant, with safe and explosion-proof performance;

(3) the contact point is full asphyxiation, no power supply is required, leakage current and residual voltage are zero, which solves the problem of "loss of signal" and "error of sending message" caused by leakage current and voltage drop when the proximity switch is working in programmable controller, PLC and DCO system;

(4) the feedback probe can be installed and debugged simply without tools. It can be moved by hand only, with a long service life. Once installed in place, maintenance is not required for a lifetime.

(5) it has a built-in inch threaded joint, which can be connected with various metal joint sleeves.
