Introduction

Honeywell Sensing & Control (S&C) offers an impressive range of environmentally sealed limit switches, basic switches, and sealed products. Many environmentally sealed limit switches incorporate the gold standard of basic switches — the MICRO SWITCH SM/SX series — to deliver enhanced precision and reliability under most extreme conditions. The sealed product line includes switches that transmit force and motion to the mechanism through a metal diaphragm while maintaining a hermetically sealed contact. High-temperature products feature switching elements mounted on ceramic bases with stainless steel housings. Honeywell S&C's flexible sealed switch product line opens powerful new possibilities for applications.

Features

• Sealed Limit Switch EN Series: Environmental sealing per MIL-PRF-8805, Symbol 4; MIL-PRF-8805 compliant; rugged stainless steel housing; environmental sealing resists the harshest environments; different contact materials (silver and gold) allow control of up to 15A logic-level loads at 28V DC; top plunger and roller plunger actuators with internal ice-scraper rings
• Sealed Limit Switch HE Series: Similar construction to EN Series, HE Series offers a higher sealing level with contacts enclosed in a sealed cavity; typically meets or exceeds the mechanical and electrical life specified by MIL-PRF-8805; designed to meet dust-proof, explosion-proof, ice-proof, minimum current, and moisture-resistant requirements; top plunger and roller plunger actuators with internal ice-scraper rings; multiple actuator and terminal options; stainless steel housing
• Sealed Limit Switch HR Series: Designed to meet MIL-PRF-8805 requirements; designed to meet moisture resistance, explosion-proof, and salt spray requirements; top plunger actuator with internal ice-scraper ring; stainless steel housing; operable at low temperatures down to -65°C [-85°F]
• Sealed Basic Switch SE/XE Series: Waterproof sealing per MIL-PRF-8805 housing design, Symbol 3; military-standard construction per MIL-PRF-8805; power load switching capability up to 7A; temperature tolerance up to 105°C [221°F]; high-temperature construction rated to 149°C [300°F]; corrosion-resistant aluminum housing isolates precision switch contacts from contaminants; multiple auxiliary actuator and terminal options; all 4SE switches UL Listed and CSA Certified; all 4XE switches UL Listed
• HM Series: Sealed per MIL-PRF-8805 Symbol 5; MIL-PRF-8805 compliant; wide temperature range -65°C to 121°C [-85°F to 250°F]; high-temperature construction -65°C to 260°C [-85°F to 500°F]; reduced sensitivity to altitude or pressure changes; compact size, lightweight; multiple actuator and terminal options

Applications

These switches are suitable for presence and absence detection applications that allow physical contact with objects. They excel in potential applications requiring compact size, light weight, precise repeatability, and long service life, including agricultural, transportation, construction, marine, and civil equipment, as well as command and control equipment.
