Sensor unit and this containing magnetic collector module

摘要

A magnetic sensor (50) of a sensor unit (40) includes magnetic detection elements (511), an encapsulation section (520), a primary terminal group (530), and a secondary terminal group (540). Another magnetic sensor (60) includes magnetic detection elements (611), an encapsulation section (620), a primary terminal group (630), and a secondary terminal group (640). The magnetic sensors (50, 60) are mounted on a common surface of a circuit board (41). Adjacent two magnetic sensors (50, 60) oriented in a common direction are arranged such that the secondary terminal group (540) of one of the adjacent two magnetic sensors (50, 60) of the primary terminal group (630) of the other one of the adjacent two Magnetic sensors (50, 60) opposite. A primary output terminal (531, 631) and a secondary output terminal (541, 641) are placed asymmetrically with each other with respect to a center line (C2, C3) of the encapsulating portion (520, 620).
