Reed Switches

Construction and Security

A reed sensor is the best choice when it comes to construction and security, due to the fact that they can work reliably in dirty environments amidst dust, grease, and oil. Unlike optic sensors, reed sensors used in dirty greasy environments are maintenance free and do not need any cleaning. A few 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.

Reed switches in Magnet Extensometers

Reed switches in Magnet Extensometers

Reed Switches are used in magnet extensometer probes to monitor settlement and heave in construction sites, dams, excavations, mines and tunnels. Access pipes are inserted into the earth, and magnets are provided… Continue reading

Reed switches and Float switches in Water tank control

Reed switches and Float switches in Water tank control

Reed Switch based float switches are used to control the pump, which fills an overhead water tank. Two of these float switches are fitted into the tank, at the near empty level and the full level. These signals are given to… Continue reading

 

Reed Sensors in Tamper Proof Utility Meters

Reed Sensors in Tamper Proof Utility Meters

Electricity meters, water meters, and gas meters use a reed sensor to prevent unauthorized opening of the panel covers. The reed sensor is mounted inside the housing with a magnet on the cover. If the meter cover is opened… Continue reading

Magnet sensors in Adjustable chairs and beds

Magnet sensors in Adjustable chairs and beds

Chairs and beds with electronic controls for adjusting tilting and height use reed sensors to sense intermediary and end positions. A magnet is mounted on the moving part with the reed sensor mounted… Continue reading

 

Reed switches in Blowers

Reed switches in Blowers

In blowers and vacuum ducts, a vane with a tiny light magnet is fitted across the flow of air, inside the duct. A reed sensor is mounted outside the duct. Nominal flow of air lifts the vane and keeps it near the reed sensor… Continue reading

Reed sensors in Power switches for explosive areas

Reed sensors in Power switches for explosive areas

Reed Switches, being hermetically sealed and unaffected by the atmosphere and surroundings, can be used with sliding magnets to work as on / off switches in explosive areas, for example, in mines where arcing could cause… Continue reading

 

Reed sensors in Emergency lamp holders

Reed sensors in Emergency lamp holders

When emergency lamps are taken off their holders, a buzzer should sound. The lamp itself can be built with a small magnet, and a normally closed reed sensor can be mounted on the holder. As long as the lamp is in its holder… Continue reading

Reed switches in Floor detection in Elevators and Lifts

Reed switches in Floor detection in Elevators and Lifts

Latching reed sensors can be mounted on every floor, and a magnet on the elevator or lift will actuate them as floors change. Latching reed sensors can be mounted in two ways with respect to the pole of… Continue reading

 

Proximity Sensors for Door and window Security

Proximity Sensors for Door and window Security

Magnets can be mounted on doors and windows, and reed sensors, on the fixed frames. As long as the doors or windows remain closed, the contact is not broken. Normally open (NO), or normally closed (NC) reed sensors can be… Continue reading

Reed switches in liquid detection probes

Reed switches in liquid detection probes

Reed switch based float switches are fitted with a perforated sheet around the whole float assembly. This assembly can be used as a depth probe and lowered into narrow bores with the help of the lead wire… Continue reading
