Honeywell MICRO SWITCH EN Limit Switches
Honeywell MICRO SWITCH EN Limit Switches are environmentally sealed, bushing-mount designs and qualified to MIL-PRF-8805 standards for commercial or military aircraft as well as ground-based equipment. These EN series limit switches come with rugged stainless-steel housing and a bushing that provides precise, reliable position indication of critical applications on defense systems. The MICRO SWITCH environmentally sealed limit switches offer an electrical rating of up to 15A at 28VDC with an insulation resistance of 500VDC. Honeywell MICRO SWITCH EN limit switches with a mechanical life of more than 25000 cycles can be used in landing gear systems for commercial and military aircraft, including helicopters, off-road construction equipment, and military ground vehicles.
Features
- All-metal drive train for consistent operating characteristics at high or low temperatures
- Assortment of switch actuators and electrical terminations
- Circuitry options from 1PST circuits to 6PDT circuits
- Gold-bifurcated, gold-plated, or silver-alloy switch contacts for reliably controlling electrical loads from less than 0.5A up to 15A
- MIL-PRF-8805 symbol 4 sealing to keep dust, water, and ice from entering the switch enclosure
- Miniature package size reduces housing diameter by 30% for smaller space required on equipment
- Most EN catalog listings are MIL-PRF-8805 compliant for stringent military and non-military applications
- Precise and reliable position indication of critical applications on aircraft and military systems
- Rugged stainless-steel housing and bushing
Applications
- External doors and hatches for commercial and military aircraft including helicopters
- Landing gear systems for commercial and military aircraft including helicopters:
- Landing gear bay doors closed/locked
- Up-lock and down-lock sensing
- Weight-on-Wheels (WOW) switch for landing gear
- Military ground vehicles
- Off-road construction equipment
