The access control induction coil is produced by a variety of wire
materials (0.012-2mm), high-quality winding, welding, measurement
and other automatic and semi-automatic process production according
to customer requirements, using high-quality induction coils,
high-quality raw materials, with simple and reliable structure,
There are only automatic winding machines, artificial mucous
membranes, high inductance precision, small distributed
capacitance, high self-resonant frequency, small temperature
coefficient, good stability, and strong anti-interference ability.
It is an inductor that can be applied at high frequencies.
Intelligent ic, id card induction coils can usually be used as
current transformers, with a wide frequency band, small size, light
weight, convenient for digital measurement, and microcomputer
protection.
