TT Electronics/Optek Technology OHN3020U

OHN3020U Overview
Designed to protect magnetic switches from damage, the Bulk package contains the switches. In order to ensure safety, magnetic switches are packaged in 3-SSIP packages. In order to function well, magnetic switches should be able to supply a maximum current of 7mA. The maximum current these switches can supply when they work is 25mA. To output current, magnetic switches should be set to 25mA. Normally, these switches supply 7mA current. Switches have 3 pins for operation. Switches should generally produce 21mA current. For the magnetic switches, 85°C is the maximum operating temperature. For this magnetic switch to function, however, the operating temperature cannot be below -20°C. When the magnetic switch operates, it could supply 12V voltage. In this electronic component, the maximum voltage is 24V. The minimum voltage of these switches can be set to 4.5V.
