OHN3140U Overview
It is protected against damage by being packaged in a Bulk. 3-SSIP packages are used to protect the magnetic switches from damage. In order to be effective, magnetic switches can provide a maximum current of 7mA. The maximum current these switches can supply when they work is 25mA. For magnetic switches, the maximum current should be 25mA. It is possible for these switches to supply a maximum current of 7mA. During operation, the switches have 3 pins. In general, the current output by the switches should be 21mA. For the magnetic switches, a maximum operating temperature of 85°C may be set. To function properly, this magnetic switch needs an operating temperature greater than -20°C. As a maximum voltage, this electronic component could supply 24V. Using these switches, you can set the minimum voltage to 4.5V. This device can theretically supply 4mA if it is working.
