PCB RS mounting

1, The description of Miniature PCB Mountable Reed Switch.

The Original glass reed switch is fragile  , Using the ABS material to protect the glass tube .The MS03 or MS04 is an encapsulated molded dry reed switch. A miniature, PCB mount reed switch with a normally open contact. Contains molded stand-offs to allow board washing. Available with customer-defined sensitivity. Capable of switching up to 200Vdc at 10W. Available with a range of sensitivity options. Well suited for position and limit sensing, security, door and window alarm systems.   

This reed switch can be populated easily on a PCB and is encapsulated so it’s more durable than glass reed switches.

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.
