Title (EN) STROKE DETECTION DEVICE
(FR) DISPOSITIF DE DÉTECTION DE COURSE
(JA) ストローク検出装置
Abstract:
(EN) This stroke detection device (100, 200) is provided with a magnetic detector (50, 250) for outputting a signal that corresponds to a magnetic field that varies in accordance with a scale (60, 260). The magnetic detector (50, 250) has a first Hall element (51, 251) for detecting variation in magnetic flux, a first magnet (52, 252) for generating a first magnetic field (M1), and a second magnet (53, 253) for generating a second magnetic field (M2). The first magnet (52, 252) and the second magnet (53, 253) are disposed so that the first magnetic field (M1) and the second magnetic field (M2) are offset in the first Hall element (51, 251).
(FR) La présente invention concerne un dispositif de détection de course (100, 200) qui est pourvu d'un détecteur magnétique (50, 250) destiné à transmettre un signal qui correspond à un champ magnétique qui varie en fonction d'une échelle (60, 260). Le détecteur magnétique (50, 250) comprend un premier élément de Hall (51, 251) destiné à détecter une variation du flux magnétique, un premier aimant (52, 252) destiné à générer un premier champ magnétique (M1) et un second aimant (53, 253) destiné à générer un second champ magnétique (M2). Le premier aimant (52, 252) et le second aimant (53, 253) sont disposés de telle sorte que le premier champ magnétique (M1) et le second champ magnétique (M2) sont décalés dans le premier élément de Hall (51, 251).
(JA) ストローク検出装置(100,200)は、スケール(60,260)によって変化する磁界に応じた信号を出力する磁気検出器(50,250)を備える。磁気検出器(50,250)は、磁束の変化を検出する第1ホール素子(51,251)と、第1磁界(M1)を発生させる第1磁石(52,252)と、第2磁界(M2)を発生させる第2磁石(53,253)と、を有する。第1磁石(52,252)及び第2磁石(53,253)は、第1磁界(M1)と第2磁界(M2)とが第1ホール素子(51,251)において相殺されるように配置される。
