Honeywell VF360NT and VF360ST Sensors


Honeywell’s VF360NT and VF360ST High Sensitivity Latching Digital Hall-Effect Sensor ICs are small, sensitive and versatile devices that are operated by the magnetic field from a permanent magnet or an electromagnet. They are designed to respond to alternating North and South poles. The VF360NT is turned ON by a North pole, while the VF360ST is turned ON by a South pole. This sensor IC does not use chopper stabilization on the Hall element, providing a clean output signal and a faster latch response time when compared to competitive high sensitivity Hall-effect bipolar latching sensor ICs which do use chopper stabilization.


  • Qualified to the AEC-Q100 standard for potential use in automotive applications
  • Fastest response time in its class [1.5 μs]
  • Operate from 30 Gauss typical at 25°C [77 °F] and 55 Gauss maximum over the full -40 °C to 150 °C [-40 °F to 302 °F] temperature range
  • Latching magnetics
  • Repeatable magnetics (no jitter)
  • No additional electronic noise generated by sensor
  • Non-chopper-stabilized design
  • Subminiature SOT-23 surface mount package supplied on tape and reel (3,000 units per reel)
  • 3 Vdc to 24 Vdc
  • Built-in reverse polarity protection
  • RoHS-compliant material

Sealcon Connectors


Sealcon circular connectors include: M16, M23, M40, RJ45, PoE, Twilock and Twintus. These connectors are field assembly-ready, meaning no special tools are required to insert or extract the contacts. They are also modular in order to meet a variety of configurations. They have a reliable connection due to the contacts’ low plug-in force and high mating cycles. The pre-tinned contacts mean these connectors are a more Reliable, Faster and Safer means of soldering. The Inserts are for all types of contacts including Crimp, Solder & Dip Solder.

Sealcon connectors have the following benefits:

  • Radially arranged copper beryllium spring contacts
  • The outside contour of the socket results in a perfect concentric alignment during connection
  • Best conductivity due to gold-plated contact area
  • Reduced assembly time due to tinned soldering ends

Typical Industries:

  • Automation
  • Automotive
  • Diagnostic
  • Hazardous
  • Marine
  • Medical
  • Motors
