Description
Description
The 30.5 mm pushbutton line features a zincdie cast construction with chrome-platedhousing and mounting nut. The samedurable construction is also available withthe corrosive resistant E34 Series ofpushbuttons.
The contact blocks feature enclosedsilver contacts with pointed "reliabilitynibs" for reliable performance from logiclevel up to 600V. To ensure reliableswitching, nibs bite through oxide whichcan form on silver contacts, eliminatingthe need for expensive logic level blocksfor most applications.
Reliability nibs improve performance indry circuit, corrosive, fine dust and othercontaminated atmospheres.
Under normal environmental conditions, theminimum operational voltage is 5V and theminimum operational current is 1 mA,AC/DC. For operation under a wider range ofenvironmental conditions, logic level contactblocks with inert palladium tipped contactsare recommended.
10250T Series operators have "groundingnibs"?4 metal points on the operatorcasting designed to bite through most paintsand other coatings on metal panels toenhance the ground connection when theoperator is securely tightened.
The 10250T pushbuttonoperators offer front of panel drainage via holes in the operator bushing. Hidden fromview by the mounting nut, these holesprevent buildup of liquid inside the operator,which can prevent operation in freezingenvironments. The holes also provide a route for escaping liquid in high pressurewashdowns, effectively relieving pressurefrom the internal diaphragm seal. Thisensures reliable sealing in applications evenbeyond NEMA 4.
