Honeywell 4AV19F Magnetic Sensor Blade Sensor

Honeywell 4AV19F Magnetic Sensor Blade Sensor

Specs:

Brand: Honeywell
Model: 4AV19F
Supply Voltage: 4.5 VDC ~ 26.5 VDC (compatible with 5/12/24V industrial control systems)
Output Type: NPN Current Sinking
Maximum Output Current: 40 mA
Static Supply Current: Typical 18.5 mA
Switching Frequency: DC ~ 100 kHz (no minimum speed limit)
Output Voltage Drop: ≤0.4 V
Operating Temperature: -40°C ~ 125°C

Core Working Principle:
The sensor integrates a Hall IC and a permanent magnet; when an iron blade passes through the sensor slot, the magnetic field is diverted, and the Hall chip output level flips; used to detect if a metal blade has entered the slot.
No extra magnets needed;
Only responds to ferromagnetic metals—non-ferrous metals like copper and aluminum will not trigger it.

Application Scenarios:
Device limit switches, position detection
Gear speed measurement, RPM collection (gear disc speed detection)
Door position feedback, cam synchronization positioning
Engineering machinery, automation equipment, aerospace position signal collection
