This is a replacement for the Philips IntelliVue MP Series (MP20 MP30 MP40 MP50 MP60 MP70) Patient Monitors Navigation Speed Point Controller Knob, originally parts numbers M8003-47402 and 451261019561.

Please note that this is a knob that I manufactured myself for the purpose, NOT an OEM part. The appearance and material are different, but the part functions just like the original. It is brand new and slips easily onto the post. It is intended as a more affordable alternative to the part that is frequently lost because it can pull off easily.

Please let me know if you have any questions. I can make more of these if necessary, such as for a large batch.
