Rare reed switches up to 5kV voltage will be great in your DIY with xenon tubes, neon tubes, other HV parts! Lot consist of 3 pieces of tubes!

Reed switches MKA-52141 gr. B are designed for switching electric circuits of direct and alternating current with a frequency of up to 10 kHz with active and inductive load, voltage up to 5000 V, current up to 3 A and switched power up to 50 W.

Reed switches MKA-52141 gr. B have make contacts (type of contacts - normally open)

 sensitivity group - B.

Normally open.

Mounting type - in holes, for soldering.

 The contacts of the reed switches MKA-52141 gr. B are located in a completely sealed glass case, which allows them to be used in conditions of high humidity, dust and a wide range of operating temperatures (from -60 ° C to 125 ° C).

 Reed switches are widely used in switching products, such as: controlled relay contacts, magnetic switches, various sensors in household, industrial and special equipment, measuring devices. 

At the limit of the switching resource, operation failures can occur - the phenomenon of welding or sticking of contacts. This is due to mechanical, chemical (corrosion) and electrothermal effects. 

Characteristics, decoding of symbols, device, drawings and dimensions are indicated below. Our company guarantees the quality and operation of reed switches MKA-52141 gr. B for 2 years from the date of their acquisition, which is supported by quality documents.
