The E34 Series 30.5 mm pushbutton line
features the same rugged die cast
construction of our 10250T line with an
additional two layer 100% solid thermosetting
cathodic epoxy coating. This coating provides
a flat black smooth, consistent, corrosion
resistant surface that has passed
a demanding 600 hour salt spray test. (The
industry standard for this 4X test requires
only 200 hours.) E34 cathodic coating is not
recommended for use in applications where exposure to ultraviolet light exists—use
NEMA 4X 10250T operators.
The contact blocks feature enclosed silver
contacts with pointed "reliability nibs" for
reliable performance from logic level up to
600V. To ensure reliable switching, nibs bite
through oxide which can form on silver
contacts, eliminating the need for expensive
logic level blocks for most applications.
The E34 Series pushbutton operators offer front of panel drainage via
holes in the operator bushing. Hidden from
view by the mounting nut, these holes
prevent buildup of liquid inside the
operator, which can prevent operation
in freezing environments. The holes also
provide a route for escaping liquid in high
pressure washdowns, effectively relieving
pressure from the internal diaphragm seal,
ensuring reliable sealing in applications
even beyond NEMA 4.

Note: To order a complete system, add a contact block and legend plate to operator. All operators and indicating lights come with instruction manual. Ordering Example: (1) E34JB2 Red jUMBO mushroom head operator, $70.00, plus (1) E34SP34 STOP Legend Plate, $3.40, plus (1) 10250T2 Contact block, 2 NO, $27.50, $70.00 + 3.40 + 27.50 = $100.90
