5550 and 5550G mechanical vibration switches provide basic, economical vibration protection by means of a simple and highly reliable “over center” snap action mass and spring mechanism. In the presence of sufficient vibration along the switch’s sensitive axis, the switch snaps from a stable “untripped” state to a stable “tripped” state, allowing automatic machinery shutdown or alarming when excessive vibration occurs. Once tripped, the switch must be returned to its untripped state via its local reset plunger (5550 only), or via voltage applied to its remote reset coil (standard on 5550G, optional on 5550). A single set of silver-plated SPDT relay contacts are provided as standard for connecting the switch to a machine control or annunciation circuit. An option for DPDT contacts is also available, and for extremely corrosive environments, gold-plated relay contacts may be ordered.
Metrix 5550 / 5550G Vibration Switch
Metrix mechanical vibration switch is designed to meet all requirements in a single, affordable package. It provides vibration protection for low to medium speed machinery. An inertia sensitive mechanism activates a snap-action switch with SPDT output contacts if the vibration exceeds an adjustable setpoint. The 5550 mechanical vibration switch contacts can be used to activate an alarm or initiate equipment shutdown. The housing is weatherproof with an optional hazardous area rating. Electrical (remote) reset with start-up time delay and a second set of SPDT output contacts to accommodate DPDT needs (e.g. separate trip and trip light circuits) are available.
The 5550G uses identical internal mechanisms, but carries an IECEX rating ideal for IIC gas group applications.
