The Phoenix America technical team will continue to make available Application Notes to educate our users and make implementation of magnetic technology more efficient. Please continue to check back to this page as we will be adding new items periodically. As always, our team is ready to support you need by phone or in person.

Application Note #07-001


The majority of Phoenix America’s sensors are constructed with an NPN open collector (or N Channel open drain) output stage. This configuration is versatile and allows for easy connection to a wide variety circuit configurations. The two main constraints to be kept in mind when implementing a connection with an open collector output are output voltage and output current. Fortunately, these limitations are easy to understand and are described herein..
