MICRO SWITCH™ Sealed and High Accuracy Switch Line Guide - Honeywell Sensing and Control - #1

Text version of the page

Engineered smarter. Basically better. Honeywell Sensing and Control (S&C) offers an impressive collection of 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 extreme conditions. The hermetically sealed lineup includes 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. Honeywell S&C’s flexible sealed switch line opens the door to new, powerful possibilities for your applications. FEATURES SEALED LIMIT SWITCHES EN Series. 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: 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. HE Series. 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 to meet sand and dust, explosion, icing, continued on page 4 minimum current, and moisture resistance requirements • Top plunger and roller plunger actuators have an internal ice scraper ring • Variety of actuators and terminations • Stainless steel housing 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. HR Series. 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 scraper ring • Stainless steel housing • Operates at low temperatures (-65 °C [-85 °F]) Benefits: Combines enhanced sealing and high temperature capability into one package. Potential applications include aircraft engine thrust reversers. SEALED BASIC SWITCHES SE/XE Series. 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 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 XE Series. Potential applications include aircraft, ordinance, and moist or dusty industrial environments. MICRO SWITCH™ Sealed and High Accuracy Switch Line Guide
