1, Description of Limit magnetic reed switch:

The Original glass reed switch is fragile  , Using the ABS material to protect the glass tube .The MS01 or MS02 is an encapsulated molded dry reed switch. It is single-pole, single throw (SPST) type, having normally open ruthenium contacts.  A sub-miniature overmolded reed sensor with either straight leads. Provided with normally open contacts. Capable of switching up to 200Vdc at 10W. Its package contains molded stand-offs to allow board washing. Available with a range of sensitivity options, including customer-defined sensitivity. Also they can bear high temperature hardy. Well suited for position and limit sensing, security, and door/window alarm systems.

Frequently Asked Questions (FAQ)

We’ve listed Frequently asked questions (and answers) pertaining to theory and usage of reed switches, reed sensors and magnets.


Q: Does all reed switches are import?

A: Mostly come from import, also Misensor own product standard reed switch with high performance and quality. 


Q: From which countries to import?

A: The United States and Japan.


Q:  Does reed switch has CE or ROHS approval? 

A: Yes.


Q: How should Reed Switches be stored?

A: When storing Reed Switches, Magnets, and related products, care should be taken to ensure that the storage area is thermally stable without too much of a temperature fluctuation. Another point to note it to avoid storing these products near strong magnetic fields that could increase the magnetic remanence of the reed blades and cause sticking.


Q: How is contact rating linked to switching voltage and switching current ?

A: Switching voltage and switching current should not exceed their individual maximum ratings and the product of voltage and current should not exceed the maximum contact rating in watts.


Q: How do Ferro-magnetic parts affect a Reed Switch?

A: Ferro-magnetic parts such as screws, nuts, bolts increase or decrease the magnetic flux that an actuating magnet brings towards a reed switch. Such parts can cause later or early operation, intermittent operation or no operation. Other sources of magnetic interference may also be caused by nearby motors, coils and relays. 


Q: Notice things when using reed switch.

A: Reed switch can not fall from a height, violent impact, when processing or welding, please use a specific tool, otherwise will effect the performance. 


Q: What about the delivery time?

A: Generally 1-4 weeks after payment; the stock items can be delivery immediately .


Q: How about the Payment? 

A: Generally T/T and PayPal , also accept others way.


Q: How about the packaging? 

A: Usually use export paper baggage, 100 pcs in one box, this is depend on specific situation.


Q: Which express company do you offer? 

A: DHL, UPS, EMS, FedEX and so on popular company.


Q: How long the quality assurance? 

A: One year assurance.
