Phoenix Contact MVSTBW and MVSTBR Strain Relief Change Phoenix Contact is modifying the strain relief tab attached to the plug to have a slightly smaller attachment area to aid in the manufacturing process. Research has indicated that the smaller size assists in the adhering the strain relief tab to the connector body without any change to the strain relief tabs functionality. No features of the plug and strain relief tab have been affected by this change. During transition of the changes, both versions of this product may be supplied depending on inventory. Please contact a Mouser Technical Sales Representative for further information. 5-0813-33
