OHN3120U Overview
Designed to protect magnetic switches from damage, the Bulk package contains the switches. For safety reasons, the magnetic switches are packaged in 3-SSIP packages. For good performance, magnetic switches can supply 7mA as their maximum current. When these switches are working, 25mA is the maximum current they can output. It is recommended that magnetic switches should have a maximum output current of 25mA. There is 7mA maximum current that these switches can supply. During operation, the switches have 3 pins. As a general rule, switches should output a current of 25mA. It is possible to set the maximum operating temperature for the magnetic switches to 85°C. The magnet switch should work, however, if the operating temperature is greater than -20°C. It is possible for the magnetic switches to supply a voltage of 12V when they are operating. In this electronic component, the maximum voltage is 24V. A minimum voltage of 4.5V can be supplied by these switches. In theory, it should be capable of supplying 9mA when it is working.
