An alternative to mercury switches! High-power reed switch: Bestact.
High Power Reed Switch: Bestact BRE/BRG Type
Industry-leading class with a current rating of 13A, maximum contact capacity of 150W, and insulation resistance of 10 to the power of 13 Ω, all in a compact size! Capable of handling a wide range of loads, including inductive loads and small loads!
**High-Power Reed Switch: Features of Vestact BRE & BRG** ● Industry-leading current capacity - Achieves a maximum current of 13A with dry reed switches (approximately 2 to 5 times that of competitors). - Applications that previously required multiple switches to handle over 10A can now be managed with a single Vestact switch, contributing to miniaturization of equipment and cost reduction. ● High capacity, high insulation, and compact size - Maximum contact capacity of 150W, insulation resistance of 10^13Ω, and approximately 18% size reduction compared to competitors (glass tube length 37mm). - Among large-capacity reed switch types, it is the smallest in its class, contributing to the miniaturization of equipment. ● Capable of handling a wide range of loads, including micro-loads and inductive loads - For micro-loads of DC5V 1mA, it can be used with a failure rate of 5 in 100 million cycles or less. - Direct switching of large time constant inductive loads is possible, eliminating the need for protection circuits.

basic information
Relays and proximity switches that use Bestact have been adopted for nearly half a century in markets such as railways, power, and steel, where high reliability is required for life-critical equipment, as well as in industrial equipment where reliable switching is expected. Case studies: https://www.bestact.co.jp/industries The reason for continued selection is that Bestact features a unique (twin contact structure) that separates the magnetic contact area from the contact point, making it a special type of reed switch. This structure allows Bestact to achieve interruption through glow discharge, which has a shorter interruption time and less contact wear compared to interruption caused by arc discharge, thus realizing long life and high reliability. Additionally, the ability to directly open and close inductive load devices (such as electromagnetic valves, solenoids, and contactors) with a maximum time constant of 100 ms is also one of the reasons for its continued selection. 【Sales Information】 Inquiries regarding quotes and delivery times can be made through the contact form below. https://www.bestact.co.jp/contact/tech-support-bestact *It is also available for purchase on the electronic components e-commerce site "DigiKey."

Company information
For over 40 years, our relays and sensors have been used in various markets where reliability and safety are required, such as in Shinkansen (bullet trains) and steel manufacturing. With advantages such as an electrical lifespan that is twice that of general relays and a failure rate that is 1/20 under minimal loads, our products contribute to improving equipment reliability while also reducing running costs by decreasing the frequency of replacements. Leveraging the excellent environmental resistance of our products, they perform well even in harsh environments, such as in vegetable factories where humidity is present.
