About This Product

■Summary

The 5550 and 5550G are basic and economical mechanical vibration switches with a simple and reliable over-center snap action (mass and spring mechanism). The switch snaps from the OFF (normal: spring-loaded) state to the switch-ON (abnormal: spring-loaded) state based on the vibration of the measurement target. This allows the device to automatically shut down or issue an alarm if excessive vibration occurs. Once the switch is turned on, it is necessary to press the reset button (plunger) on site to turn it back off. (5550 only) Alternatively, remote reset operation is required using an external voltage supply. ("5550G" is standard equipment, "5550" is optional) There is 1 silver plate SPDT relay to connect the switch to the machine control or control circuit. Additionally, DPDT is available as an option, and gold plated plates are also available for use in highly corrosive environments.

■Selection criteria

The 5550 and 5550G use the same mechanism, but differ in terms of housing shape, installation area, explosion-proof area, and external control method. The 5550G housing can be used in high IIC explosion-proof areas, but it cannot be reset in the field or set using adjustment screws. The installation space is also larger. For these reasons, ``5550'' is generally selected as a suitable switch except for IIC explosion-proof areas.

■Remote reset/startup delay

The "Remote Reset/Restart" function is standard on the 5550G and optional on the 5550. When the reset terminal of the switch is energized, the solenoid coil is activated. After this solenoid coil resets the switch (trips it), it maintains a dead zone (untripped state) for about 30 seconds, after which the switch returns to normal operation. This function is effective when the device vibrates higher than usual at startup, and when it is necessary to prevent the device from reacting until the vibration subsides during normal operation. The high retention strength of this solenoid coil allows it to be forced into a position where it will not trip, even in the presence of high vibration levels. Additionally, you must specify specifications that can be maintained during the startup delay. (Option: see “C”)
