A record of accomplishments that the high reliability of Bestact Since Bestact, a heavy-duty reed switch with a hermetically sealed glass contact, was put on sale, over 20 million Bestact units in total have been used worldwide in rolling stocks, electric power equipment, elevators, and control devices in heavy chemical complexes and steel mills. Bestact was developed in step with the history of Shinkansen „Bullet“ trains since it was adopted in 1982 for the first time. Presently, Bestact is used for all Shinkansen „Bullet“ trains. With an increasing demand for components with high contact...

Trusted partner of companies well known for their reliability ATS relays Door interlock switches Auxiliary contacts for breakers Plug-in relays Board mounted relays Output contacts for master controllers

Bestact application examples A manned train uses Bestact products for a variety of operating switches and relays of the master controller manipulated by the driver. Besides, Bestact switches and relays are used to detect and output handle notch positions to stop the train or maintain the power running of the train, etc. Bestact switches are applied to door opening and closing buttons operated by the train crew at stations where the train stops as well as door interlock equipment to ensure the safety of passengers. Furthermore, Bestact relays are applied to the control relay board that...

for train control equipment Master controller The driver of an electric car selects an appropriate notch according to the situation in control of speed. A Bestact magnetic proximity switch is used to confirm the notch position while Bestact board- mounted and plug-in relays are used as notch output contacts. Furthermore, Bestact products are used for the contacts of train door opening and closing buttons operating at a low voltage (24 VDC) in compliance with the Train Information Management System (TIMS). Variable Voltage Variable Frequency (VVVF) Inverter drive The controller of an...

Bestact train control equipment Auxiliary contacts for vacuum contactors Auxiliary contacts for vacuum contactors are mounted in the control cabinets under the train floor. The vacuum contactors open and close when the train passes electrical substation. Bestact contact units are used as auxiliary interlocking contacts in vacuum contactor in control of the main converters of the VVVF drive. Control cabinets under train floor Typical auxiliary contacts for vacuum contactors Product Model PPMU-E Contact Unit PSPD-07G Contact Unit PSPE-05E/05G Contact Unit Built-in switches Automatic Train...

Automatic Train Operation (ATO) The automatic train operation (ATO) is a device that provides automatic train operation between stations for train acceleration, constant speed, and deceleration and stop location control within specified positions at stations. It uses a transponder for sending/receiving information signals between cab-side and wayside coils on station names, upcoming destinations, and respective train identification numbers. The ATO supports the operation of crewmembers and ensures the safety of passengers by means of stopping trains precisely at specified positions at...

Door control device (for Shinkansen “Bullet” trains) The door control device is a safety device to ensure the safety of passengers. Door interlock switches are mounted in door pockets, confirming the open/close status of passenger doors. The door control device consists of a changeover switch, conductor switch, door closing mechanism, door-closing switch, doorclosing safety mechanism, and indicators. Normally, door interlock switches for multi-car trains are connected in series, providing input signals to operator room indicators, magnetic valves for door operation and car side lamps....

Railway signals and Bestact products Automatic Train Stop (ATS) The automatic train stop (ATS) basically issues a warning when a train approaches a stop signal and the distance between the train and the stop signal becomes less than a certain extent (i.e., the braking distance plus a safety margin). If the train driver does not respond to the warning, the ATS will automatically brake and stop the train before the train passes the stop signal in order to prevent accidents, such as collisions or derailment. The pickup on the train always generates a wireless signal, and the ATS will be...

Obstruction warning device for level crossing (Emergency stop button) This warning alarm device for train crossings warns train operators if there is an obstruction at a crossing where the trains are approaching. The warning is triggered by an emergency push-button. This device is seldom used, but the overall performance of it requires reliability. Typical switches and relays for emergency stop buttons Product Model PSMO-04G2S Magnetic Proximity Switch PBR Pushbutton Switch RI-B15MH Relay Obstruction warning switch for tracks The obstruction warning switch for tracks is a device used to...
