Shock and vibration, and extremes of humidity and temperature are faced by most domestic goods. Reed Sensors come in packages which withstand all of the above. They also have the added advantage of directly switching 110V / 230VAC line voltage. The most widely used white goods applications are listed below. We have also suggested few of our products for use in each application, but this does not mean that the other products in the same product category will be unsuitable.

Portable ACs cool an area by first removing the humidity in the room and this water gets filled into a tank that needs to be drained when full. Reed Switch based float switches are fitted in these tanks to trigger an audio-visual alarm. Continue reading |

Proximity sensors or Reed Sensors are used near under the top loading door to stop the cycle instantly, if at all the loading door is inadvertently opened in-cycle. This helps stop the motor as well which could cause an accident. Continue reading |

Pedals in sewing machines use a potentiometric or a similar arrangement as a wound coil with a moving carbon brush to control speed of the stitching motor. The disadvantage of such a system is that the carbon brush wears out and the stitching speed varies over time. A reed sensor… Continue reading |

Reed Switches are used in bi-directional vibration sensors. A magnet and a very precise tension spring is inserted into a cylindrical housing and sealed on both ends. Two of these cylindrical assemblies are mounted on either side of a reed switch in such a way… Continue reading |

In deep freezers, coolers and heaters, the temperature needs to be maintained within a precise window. Thermal reed sensors can be designed having windows as small as 2°C up to 10°C, and can switch up to 60W directly. The sensor can control the switching on… Continue reading |

Mixers, food processors and grinders have an inbuilt over current protection which cuts off the power to the motor whenever the grinding blades or mechanical parts get obstructed. A reed switch can be used to build a current sensing relay which senses… Continue reading |

Electric toothbrushes have to change the direction of the motor when switching from the top row of teeth to the bottom row. This can be done by mounting a reed sensor inside the electric toothbrush, with a magnet sliding in a groove on the outside… Continue reading |

After rice has cooked, rice cookers need to keep the rice warm at say, 70°C. This can be achieved by using a thermal reed switch designed to cut off at 75°C and cut in at 65°C. This opening and closing signal can be used to trigger a relay or a contactor… Continue reading |

When dish washers are working, the high power water spray could dislocate some of the lighter dishes in the carrier and lodge them along the spray arms path. The next time the spray arm passes, it could jam the system. Reed Sensors can be… Continue reading |

In washing machines and dish washers, the processor needs to know that the door is closed, so that the automatic cycle can be started and water can be pumped into the system. In refrigerators and deep freezers, a door left slightly … Continue reading |

Washing machines and dishwashers have reservoirs to hold detergent, and fabric or water softeners. A window is usually given behind the door of the appliance to check the level. With time, this window gets stained, and it is difficult to view… Continue reading |

Domestic coffee machines use an inlet water hose which is triggered by a solenoid to fill up the water reservoir whenever needed. As the water drains, the float comes down and activates a reed sensor, and this signal can be used to trigger the input water solenoid… Continue reading |

Commercial coffee, tea, and milk vending machines need to dispense enough milk or water for exactly one cup. This can be accomplished by filling up a secondary reservoir fitted with a reed switch and a float which comes on when the reservoir is… Continue reading |
