    摘要： In a first display mode, a threshold value is numerically displayed on a first display section and the current light reception amount (current value) is numerically displayed on a second display section. In a second display mode, the tolerance value is numerically displayed on the first display section and the current light reception amount is numerically displayed on the second display section. To switch from the first display mode to the second display mode, a display mode change key can be operated.

    摘要： A detection switch for enabling the setup sensitivity of the switch to be checked without lowering the movement speed of an object to be detected. A light reception section outputs a light reception signal RS corresponding to a light reception amount. A detection section amplifies the light reception signal RS and converts the amplified light reception signal RS from analog to digital form, then outputs the digital signal as light reception data RD indicating the light reception amount. A hold time control section 5 gives a hold timing signal HT defining a hold period to a hold circuit. The hold circuit holds the peak value or bottom value of the light reception data RD every hold period and outputs the hold value to a control section each time the end of the hold period is reached. The control section causes a display section to display the hold value.

    摘要： A core (120; 120'; or 1220) of a proximity sensor (100; 1200; or 1500) is made of a highly permeable metal and is shaped and sized to operate as a saturable core proximity sensor, a variable reluctance proximity sensor, and an eddy current proximity sensor. The core (120; 120'; or 1220) has a cross-sectional shape including a head portion (220 or 1231), two legs (222 or 1232) extending from the head portion (220 or 1231), and two foot portions (224 or 1233) (feet) extending from the two legs (222 or 1232). The head portion (220 or 1231) forms a substantially planar section along the upper surface and is perpendicular to the sectional direction created by the two legs (222 or 1232). The sectional direction of the two legs (222 or 1232) are perpendicular to the sectional direction of the two feet (224 or 1233). The two feet (224 or 1233) are in a common plane along the bottom surface. Both foot portions are also parallel to the head portion. The cross-sectional shape of the core may further comprise two tail portions (1234) (tails), wherein each tail extends from one of the two foot (1233) portions in a direction toward the upper surface (1221).
