For those who are new to magnetic measurements: Methods and precautions for measuring magnetic flux density!
For measuring magnetic flux density, a Tesla meter (Gauss meter) is primarily used, employing a magnetic sensor called a Hall element to measure the magnetic flux density. The Hall element has a defined area that detects magnetic fields, generating a voltage proportional to the magnetic flux density in the perpendicular direction to that area. Many of these sensors are very small, allowing for pinpoint measurement of magnetic flux density. [Overview] ■ Measurement methods for magnetic flux density ■ Precautions for magnetic flux density measurement - Position of the magnetic sensor - Orientation of the magnetic sensor - Temperature *Detailed content of the column can be viewed through related links.

Under the premise of a static magnetic field environment, it was utilized for verifying the shielding effect of the magnetic shielding plate through actual measurements and simulations.
![[FAQ Document] Soft Magnetic Material of Iron-Nickel 'Permalloy'](https://image.mono.ipros.com/public/product/image/bba/2000413553/IPROS48226832911360189863.png?w=280&h=280)
Attention those struggling with magnetic properties! We are offering an FAQ document about the soft magnetic material "Permalloy," which has low coercivity and high permeability! A list of thicknesses is also included.
Permalloy is a nickel-iron alloy that contains 35-80% nickel (Ni) and is supplied in various forms such as sheets and rods, similar to many other metals. Its appearance is not significantly different from stainless steel or iron, but it possesses special properties that strongly attract magnetism. Due to its low coercivity and high permeability, it has a high magnetic shielding effect and a strong magnetic collecting action. It also exhibits a large output (magnetization) in response to fine input (magnetic field), and it increases the resistance (the ratio of voltage to current) in alternating current. As a result, it is applied in magnetic shielding rooms, magnetic shielding cases, magnetic shielding boxes, magnetic sensors, and various inductors (coils with windings on a core). It is effective in a relatively low frequency range, from extremely low frequencies below 1 Hz to commercial frequencies up to 200 Hz. 【Effects】 ■ High magnetic shielding effect and strong magnetic collecting action ■ Large output (magnetization) in response to fine input (magnetic field) ■ Increases resistance (the ratio of voltage to current) in alternating current *For inquiries or consultations regarding Permalloy, please use the contact form on our company website. 【Contact】https://www.ohtama.co.jp/contact.html

Tunnel magneto-resistive sensor (TMR sensor) with high sensitivity and accuracy
Various magnetic sensors such as the Hall sensor, are widely used for the realization of an advanced IoT society. In particular, magnetic sensors based on the tunnel magnetoresistance effect (TMR sensor) discovered at Tohoku University has made dramatic progress in increasing sensitivity, making it possible to detect a weak magnetic field such as bio-magnetic field. However, the conventional TMR sensor did not achieve both high sensitivity and accuracy. This invention is able to provide a TMR sensor with extremely high linearity output which is necessary to achieve high sensitivity and accuracy, by controlling the higher-order magnetic anisotropy of the used ferromagnetic material.
Highly sensitive and wide range magnetic sensors
Magnetic sensors with wide dynamic range and high sensitivity have been developed. Various types of sensors, such as SQUID magnetometers and Hall sensors, have been used. Cantilever-type magnetic sensors using mechanical resonant frequency have especially attracted attention because of their low power consumption, small size, and potential for wide dynamic range. However, while they exhibit high sensitivity near the resonance frequency, there is an issue that sensitivity and resolution are not sufficient for magnetic fields below the resonance frequency including DC magnetic fields. The present invention relates to a cantilever-type magnetic sensor. The sensitivity and bandwidth can be adjusted electrically by introducing a magnetic excitation component. This enables high sensitivity and wide-band magnetic field detection. 【 For those who see this document 】 Since it is a seed for unpublished patents, it is possible to disclose the description after the conclusion of the IP contract.

Unlike contact-type mechanical switches, the switch part does not suffer from wear-related failures and excels in durability, safety, and reliability. It can be screwed in from two directions: horizontal and vertical. There are two types of adhesive force: 3kgf and 1kgf. It can be used for various OA equipment such as copiers and printers, as well as door sensors for FA equipment.
Leave it to us for magnetic sensors such as three-axis magnetic sensors and DC current sensors.
We handle magnetic sensors such as the three-axis magnetic sensor "FGS3-1000" and the direct current sensor "CS-2803K." The "FGS3-1000" can measure direct current magnetic fields (±1000μT) and alternating magnetic fields (1000μTo-Peak). It employs a parallel fluxgate method and outputs the X, Y, and Z axis components simultaneously. The "CS-2803K" converts the small magnetic fields generated by the input current into voltage. The input and output are completely isolated, allowing direct current to be detected simply by passing the conductor through a hole. 【Lineup】 ■ Three-axis magnetic sensor "FGS3-1000" ■ Direct current sensor "CS-2803K" *For more details, please download the PDF or contact us.
