Fenix 5x and how many ANT+ devices

Dear Community,

I wish to purchase the 5x but I wonder how many ANT+ devices I can conntect to the watch.
I have a chest strap (which I currently use with my gpsmap 64s) and I want to buy the garmin speed and cadence sensors as well.
Can the watch handle those devices simulateneously?

Cheers,
Steve
