Reed Switch - Magnetic Field Sensor (Pack of 5)
Description
- Magnetic Field Sensor
- Reed Switch
- Open/closed functionality
- Sold in packs of 5 reed switches
The Reed Switch is used as a simple magnetic field detecting sensor. When the sensor is exposed to a magnetic field, the two ferrous materials inside the glass envelope pull together and the switch closes, causing the circuit to close. When the magnetic field is removed, the reeds separate and the circuit opens. The sensor can carry up to 1.2A.
Note: Proximity and strength of the field to close the circuit must be determined by trial and error.
Instead of purchasing a commercial magnetic on/off reed switch for my marine application I used RobotShop's reed switches along with Pololu's 16A Big Pushbutton Power Switch (RB-Pol-378) and their Mini Pushbutton Power Switch (RB-Pol-345). It worked out very well, but in the process I broke 3 of the very fragile reed switches. A word of caution... When working with the reed switch you must be very careful not to bend it's leads without clamping the wire directly beside the very breakable glass reed casing. Also, care should be taken with whatever method you use to support the switch as to not put any strain the leads or casing.
Great magnetic field switch. Be careful with the glass, use needle nose pliers when bending the leads to avoid breakage. Good price for 5 pieces.
Grand commutateur de champ magnétique. Faites attention avec le verre, utilisez une pince à bec effilé lorsque vous pliez les cordons pour éviter de les casser. Bon prix pour 5 pièces.
Au lieu d'acheter un interrupteur à lames magnétique on / off du commerce pour mon application marine, j'ai utilisé les interrupteurs à lames de RobotShop avec l'interrupteur d'alimentation à gros bouton poussoir 16A de Pololu (RB-Pol-378) et leur interrupteur d'alimentation à bouton poussoir miniature (RB-Pol-345). Cela a très bien fonctionné, mais ce faisant, j'ai cassé 3 des très fragiles interrupteurs à lames souples. Un mot de prudence ... Lorsque vous travaillez avec l'interrupteur à lames, vous devez faire très attention de ne pas plier ses fils sans serrer le fil directement à côté du boîtier en verre très cassant de l'anche. En outre, vous devez faire attention avec la méthode que vous utilisez pour soutenir le commutateur afin de ne pas mettre les câbles ou le boîtier sous contrainte.
