MICRO SWITCHTM Premium Subminiature Basic Switches SX Series Datasheet MICRO SWITCHTM SX Series Premium Subminiature Basic Switches The industry-defining name in snap-action switches, Honeywell MICRO SWITCHTM premium subminiature switches are designed for repeatability and enhanced product life. The MICRO SWITCHTM SX Series delivers consistent performance within a range of conditions. Offering enhanced repeatability, the MICRO SWITCHTM SX Series' lower operating force provides for application versatility. Like the MICRO SWITCHTM SM Series, the SX Series (which is a smaller package) offers gold contacts for low energy switching and bifurcated gold contacts for maximum reliability. Bifurcated contacts provide parallel redundancy within the SX switch. What makes our switches better? *Industry-leading life cycle rating reduces the need to replace switches over life in an OEM platform - reducing total system cost Very wide temperature range allows for years of reliable performance in the harshest of conditions MIL-PRF-8805 qualified listings Operating forces as low as 0,147 N [15 g] and differential travel as low as 0,025 mm [0.001 in] delivers consistent precise switch characteristics Small in size, large in capability! COST OPTIMIZATION * PERFORMANCE RELIABILITY * GLOBAL ACCEPTANCE 2 sensing.honeywell.com Features and Benefits LONG LIFE With a mechanical life of up to 10,000,000 operations, SX Series switches boast an industry-leading life cycle. APPLICATION FLEXIBILITY MICRO SWITCHTM SX Series delivers a selection of actuation, electrical termination, and operating characteristics along with high-temperature construction options. Life of up to 10,000,000 cycles INDUSTRY-LEADING TEMERATURE RANGE With a wide temperature range of -54 C to 204 C [-65 F to 400 F], SX Series switches allow for years of reliable performance in harsh conditions. Precision switch characteristics COMPACT AND ROBUST Built from military-grade components, MICRO SWITCHTM SX switches deliver MIL-PRF-8805 qualified listings in a lightweight, subminiature package. SX switches are available with FAA-PMA approvals for commercial aircraft applications. EASILY CONTROLS LOW-VOLTAGE DC APPLICATIONS Switches available with a choice of silver, gold-plated, or bifurcated gold contacts to handle a variety of electrical load requirements. GLOBAL APPROVALS UL/CSA, cUL, ENEC, and CE approvals allows the customer to utilize switches in products sold across the globe - in some of the most regulated regions. sensing.honeywell.com 3 Potential Applications AEROSPACE * In precision switch assemblies for commercial aircraft to monitor doors for "closed" and "locked" position * Monitor whether landing gear is "up" or "down and locked" * In precision switch assemblies for commercial cockpit applications for pushbuttons, toggle, or joystick assemblies * MIL-PRF-8805 listings suitable for precision switch assemblies in military applications * FAA-PMA approvals for commercial aircraft INDUSTRIAL * In precision switch assemblies for pressure switches and temperature switches * In power generation, fuel level switch for gas and oil 4 sensing.honeywell.com MICRO SWITCHTM Premium Subminiature Basic Switches Table 1.
