KTGEE position sensor | LJK22-4015KH | High temperature resistant passive magnetic switch adopts the principle of passive magnetic induction, also known as passive feedback probe. It is made of SUS304/316 stainless steel material, which has wear resistance, high temperature resistance, and rust prevention

◆ Performance characteristics (1) This product uses SMT assembly technology to assemble various micro components for secondary assembly, with no magnetization, no wear, and anti fatigue contacts; (2) The signal is a non-contact action with no mechanical faults. Immersive, double-layer fully sealed structure, non oxidizing, moisture-proof, waterproof, acid and alkali resistant, with safety and explosion-proof performance; (3) The contact is fully suffocating and does not require power supply. The leakage current and residual voltage are zero, which solves the problems of "signal loss" and "transmission error zone" caused by leakage current and voltage drop when the proximity switch works in programmable controllers, PLCs, and DCO systems; (4) The installation and debugging of the feedback probe is simple, without the need for tools. It can be moved by hand and has a long service life. It can be installed in place at once and does not require maintenance for life; (5) Equipped with built-in British threaded interfaces, it can be connected to various specifications of metal joint sleeves.
