extreme conditions. The hermetically sealed lineup includes
Engineered smarter. Basically better. Honeywell Sensing
and Control (S&C) offers an impressive collection of
switches that maintain the contact in a gas-tight seal, while
transmitting force and motion to the mechanism through a
metal diaphragm. And our high-temperature products have
the switching element mounted on a ceramic base with
stainless steel enclosures.
environmentally sealed limit switches and basic switches,
as well as hermetically sealed products. Many of our
environmentall sealed limit switches incorporate the gold
standard of basic switches – the MICRO SWITCH SM/SX Series
– resulting in enhanced accuracy and reliability under most
Honeywell S&C’s flexible sealed switch line opens the door to
new, powerful possibilities for your applications.

SEALED BASIC SWITCHES
SE/XE Series.
resistance requirements • Top plunger
and roller plunger actuators have an
internal ice scraper ring • Variety of
actuators and terminations • Stainless
steel housing
Features: Watertight seal per enclosure
design MIL-PRF-8805, symbol 3
• Military-standard construction with
listings qualified to MIL-PRF-8805 •
Power loading switching capability up
to 7 A • Temperature tolerance up to
105 °C [221 °F] • High temperature
construction for use up to 149 °C [300
°F] • Corrosion resistant aluminum
housing seals precision switch contacts
from contamination • Several auxiliary
actuators and choice of termination
• All 4SE switches are UL recognized,
CSA certified • All 4XE switches are UL
recognized
Features: Environment-proof seal per
MIL-PRF-8805, symbol 4 • Qualified
to MIL-PRF-8805 • Rugged stainless
steel housing • Environment seal resists
most severe environments • Different
contact materials (silver and gold) allow
the control of a logic-level load of up to
15 A at 28 Vdc • Top plunger and roller
plunger actuators have an internal ice
scraper ring
Benefits: Features true hermetic
sealing (metal-to-metal, glass-to-
metal construction) designed to ensure
maximum sealing effectiveness for long
periods of time regardless of constant
changes in atmospheric pressures and
temperatures. Potential applications
include jet aircraft de-icer controls and
military aircraft wingfold actuators.
Benefits: Miniature housing
constructions are available with similar
actuator styles to meet the demand for
smaller size and lighter weight without
sacrificing performance or electrical
capacity. Potential applications include
aircraft landing gear and flap/stabilizer
controls, aircraft engine thrust reversers,
space vehicles, and armored personnel
carriers.
HR Series.
Benefits: SE and XE switches are the
smallest environment-sealed switches
offered by Honeywell. Different contact
materials allow the control of a logic-level
resistive load up to 5 A at 28 Vdc for the
SE series, and up to 7 A at 28 Vdc for the
Features: Designed to meet the
requirements of MIL-PRF-8805
standards • Designed to meet moisture
resistance, explosion, and salt spray
requirements
• Top plunger actuator has an internal ice XE Series. Potential applications include
HE Series.
scraper ring • Stainless steel housing
• Operates at low temperatures (-65 °C
[-85 °F])
aircraft, ordinance, and moist or dusty
industrial environments.
Features: Similar to the construction of
the EN series, the HE has a higher level
of sealing with the contacts enclosed
in a hermetic chamber • Often meets or
exceeds mechanical and electrical life
as defined in MIL-PRF-8805 • Designed
Benefits: Combines enhanced sealing
and high temperature capability into one
package. Potential applications include
aircraft engine thrust reversers.
