What is the High-Power Reed Switch “Bestact®*"? Among reed switches, Bestact® is classified as a heavy-duty reed switch and is defined in the IEC standard as follows. “Reed switch, in which greater switching capacity is achieved.” “Blades having additional contact tips or a contact tip and spring which separate the magnetic path and electric path are typical examples of techniques to increase switching capacity.” From IEC 62246-1-1 High-Power Reed Switch Backstop Mechanism Return Spring Magnetic Members Inert Gas Contact Parts Glass Tube Contact Chip High-performance contact due to unique...

Features of “Bestact®” contact The Contact that Enables both High Power and Small Size High Carry Current: 13A ・Enables 13A Carry Current, the largest value in dry reed switches, 2 to 5 times greater* than competitors. ・Even if several contacts are used to carry more than 10A, Bestact® allows you to use only one Bestact® instead, enabling you to downsize your devices and reduce costs. Large Contact Capacity and High Insulation Resistance in a Small Size ・Maximum Contact capacity of 150W, insulation resistance of 10¹³Ω, and approximately 18% smaller* than competing products with the same...

Examples of products incorporating Bestact® and its advantages Power Relays • Large contact capacity and high insulation resistance in a small size. • Enables over 10A carry current in a small size and lower cost. • Simplifies the circuit by switching inductive loads without protection circuits. • Long life even with inductive load switching reduces maintenance costs. • Simplifies the circuit by switching inductive loads without protection circuits. • Long life even with inductive load switching reduces maintenance costs. • Can also be used for micro loads. • Resistant to adverse...

Examples of inductive load equipment that can be controlled by Bestact® Inductive loads with large time constant can also be switched directly! Time constants for typical loads of equipment that can be switched directly by products with incorporated Bestact® Time Constant Range (ms) ０ Solenoid Valve DC Motor Clapper type Contactor Solenoid etc. The built-in bestact allows these devices to be directly switched without protection circuits. Products with built-in general reed switches require protection circuits with resistors, diodes, varistors, etc.

Differences between Bestact® and general reed switches Separation of magnetic contact part and electric contact part enables stable operation! General Reed Switch Magnetic and electrical circuits are same Magnetic and electrical circuits are separated Magnetic Circuit Electrical Circuit

Differences between Bestact® and general reed switches High vibration resistance and contact reliability due to spring mechanism! YASKAWA © 2025 BESTACT SOLUTIONS INC. | Backstop Mechanism The contact tip is pressed against the glass tube by the force of the return spring when ® . -^Vibration- and shock-resistant structure even in a non-excitation state. The contact parts make contact through motion ® to ® with a wiping motion. ^Cleans the contact surface. When the pulling force of the contacts is lost, the moving contact is flicked off by the energy of the spring on the fixed contact side...
