Comus Reed Switches


Comus offers a number of reed switch options to meet a variety of application needs. Reed switches are operated using a magnetic field generated by either a permanent magnet or current-carrying coil. Unlike other magnetic sensing devices such as Hall Effect sensors, reed switches require no power to operate. This, coupled with their very high value to price comparison makes them an ideal choice when an application requires high reliability with little to no power availability. Reed switches are available as form A (normally open), form C (changeover) and form B (normally closed).

Types of Reed Switches Include:

  • Dry Reed Switches
  • COTO Technology Reed Switches
  • Mercury Reed Switches
  • High Voltage Reed Switches
  • High Power Switch Modules

Potential Applications include:

  • Automotive
  • Domestic appliances
  • Electronics
  • Industrial applications
  • Position sensing
  • Pulse counting
  • Relay applications
  • Security applications
  • Temperature sensing

ebm-papst’s 3250J product series

ebm-papst’s 3250J product series!  
These high-performance compact fans measure 92 mm x 92 mm x 38 mm and are ideal for dissipating heat in limited space environments with lower system resistances.
ebm-papst’s proven 3200J S-Force series run at very high speeds to maintain performance against high system resistance. The 3250J S-Panther series is designed specifically for applications with lower system resistances, therefore operating at more moderate speeds so that more performance options are available to you.
Featuring an updated aeroacoustic impeller blade design with turbulator, the 3250J S-Panther series offers substantially improved acoustic characteristics. The sound power of the S-Panther is far lower than that of other fans, particularly in the higher frequency ranges starting at 1250 Hz. Operating at lower speeds, the S-Panther fans also achieve a 20-25% improvement in bearing life over ebm-papst’s higher speed S-Force fans.
Potential Applications:
  • IT/Telecom
  • IT servers
  • IT network devices
  • Switch cabinets
  • Automation
  • Solar Inverters
  • Frequency Converters
  • Commercial Refrigeration
  • Medical Technology

Honeywell’s High Sensitivity Latching Digital Hall-Effect Sensor ICs

Honeywell_VF360 copy

The VF360NT, VF360ST, and VF460S 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 and VF460S are 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 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
  • 3 Vdc to 24 Vdc
  • Built-in reverse polarity protection
  • RoHS-compliant material

Potential Applications:

  • BLDC motor commutation for automotive applications: Air input flap to engine, convertible roof position, electronic parking brakes, electronic window lifts and anti-pinch power window systems, HVAC blowers, headlights, power doors, mirrors and tail gates, seat motors, steering, windshield washers and wipers
  • Speed and RPM sensing: Motors and fans; tachometer and counter pickup
  • Flow rate sensing
