Technology Details
Iron Bar Detection (Proximity Sensing)
A metal sensing device using coils, capable of detecting the position of iron bars in concrete. By measuring the energy required for resonance, it can detect with high resolution reinforcing bars in deep positions.
Position Detection (Capacitive Sensing)
The position of a moving object can be sensed by configuring multiple electrodes and measuring each one's capacitance. Resistant to temperature changes and disturbances, this technology is applied in switches requiring position detection.
Board Design (High-Frequency Design)
For high-frequency boards, it is important to match the characteristics impedance of the signal line. High-frequency design technology realizes a high-quality board that does not reflect signals.
