Metrix 440 and 450 electronic vibration switches provide economical, self-contained, single-channel vibration protection. The 440 switch is suitable for use in non-hazardous as well as Class I Div 2 hazardous areas. The 450 switch utilizes the same internal electronics as the 440, but features explosion-proof enclosure styles suitable for Class I Div 1, Class II Div II, and Class III hazardous areas. Options are available for electronic (triac or FET) or electromechanical relay outputs, allowing the switch to be used in an auto-shutdown circuit that trips the machine under high vibration conditions.
