We manufacture highly reliable control and operation devices equipped with Bestact hermetically sealed power reed contacts such as I/O relays, magnetic proximity switches, limit switches, and command switches.
We are finding new market opportunities in robotics, mechatronics, and safety related industries, as well as expanding in existing markets. These markets include those for trains, railway signals, elevators, and electric power facilities as well as chemical, petroleum, and iron and steel plants.
Even under the harshest environmental conditions, Bestact is proving itself by providing indispensable and solidly reliable devices for use in industries worldwide.
[Railway Vehicles]
Bestact I/O Relays

Used as an interface for I/O relays for automatic train control (ATC) and variable voltage, variable frequency (VVVF) inverter control on bullet trains (Shinkansen).
[Railway Signals]
ATS Relays

Signaling relays mounted inside a transponder and installed on a railway tie as part of an automatic train stop (ATS) system. They offer vibration resistance and high contact reliability.
[Railway Vehicles]
Door Interlock Switches

Used to confirm the open/closed status of passenger doors on bullet trains (Shinkansen). Door interlock switch contacts are connected in series, providing a signal to the operator.
[Railway Signals]
Bestact Pushbuttons

Widely used in applications that vitally require high reliability, such as warning alarm systems for train crossings.
[Electric Power]
Bestact Relays for Electric Power Systems

Used as a command relay in high-voltage networks to send a trip command to high-voltage circuit-breakers and cut the power between stations where an accident or failure has occurred.
[Steelmaking]
Bestact Control Switches

Used in control panels installed in iron and steel plants under the severe operational environments.
[Machine Safety]
Bestact Built-in Safety Switches

Used as non-contact interlock safety switches for machine guard doors in food processing and packing lines as well as in semiconductor manufacturing to protect workers. They are ideal for wet, dusty, and oily environments, and also in areas where hygiene is important.
[Machine Tools]
Bestact Relay Units

Relay units, which are highly integrated with Bestact I/O relays.
[Elevators]
Bestact Vane-actuated Magnetic Proximity Switches

Used in sensors to confirm the position of elevator and to prevent the elevator from moving unless the door is fully closed.
