RELMAG electronic – About Us

RELMAG electronic s.r.o. has been operational in the Czech Republic since 1991, originally under the company name MEDER electronic CZ s.r.o.  On March 1st 2011 we changed our company name but not our core competency, which still remains the same – the production and sales of reed technology products of StandexMeder Electronics.

RELMAG electronic s.r.o. is the market leader in the field of reed technology in the Czech Republic, especially due to our 30 years of experience and the base provided by our own production plant. We are a reliable partner for the production and sales of reed relays, sensors, switches and permanent magnets, including customized solutions.

RELMAG electronic s.r.o., thanks to a cooperation agreement with StandexMeder Electronics GmbH, is a producer of the reed products of StandexMeder Electronics and the sales representative of StandexMeder Electronics in the Czech Republic, Slovakia, Poland and other countries of Central and Eastern Europe.

RELMAG electronic s.r.o. has established and applies a Quality Management System in accordance to EN ISO 9001:2016.


Our company can offer you, thanks to many years of experience in the development and production of reed technology, a modification or development of a new product that will meet your specific requirements. Below are examples of the most common adjustments for each product area.

Would you like more detailed information? Do not hesitate to contact us via our contact form.

Reed Switches

  • sorting specific magnetic sensitivity pull-in ranges
  • cutting and/or bending the reed switch contact leads for either horizontal or vertical surface mount applications or other special mounting requirements
  • examples of cutting or bending the reed switch leads can be viewed here

Reed Sensors & Magnets

  • with variety of possible different covers, type of magnets and the contact used, the sensors can be adjusted exactly according to the customer requirements for location and functionality

Reed Relay

For reed relays following parameters can be adjusted:

  • switching function – amount of switches and coils is variable
  • isolation resistance (in case of uncovered relay up to 10¹⁴Ω)
  • shielding
  • pins out
  • nominal coil voltage
  • electrostatic shielding

Level Sensors & Magnetic Floats

Custom level sensors can be modified for specific customer specification. The designs often include harsh environments, significant durability requirements, precise rate switching and modification of leads.
