Product Description

DESCRIPTION

The Honeywell MICRO SWITCH™ Series of EN limit switches are bushing mount designed, manufactured, and qualified to MIL-PRF-8805 standards. These products provide a durable switch for commercial and military aircraft as well as commercial and military ground-based equipment. Other applications include off-road equipment where severe environments are encountered.

The EN Series of switches have proven to deliver consistent and reliable operation in harsh environments on critical applications for more than 65 years.
 

VALUE TO CUSTOMERS

• Precise and reliable position indication of critical applications on aircraft and military systems
 

DIFFERENTIATION

• MICRO SWITCH™ EN Series' products are highly configurable; offering a variety of integral actuators, electrical circuitries, and electrical terminations
 

FEATURES

• Circuitry options from 1PST (one-pole single throw) circuit to 6PDT (six-pole double throw) circuits for position indication of different independent circuits or providing redundant circuit capabilities

• Rugged stainless steel housing and bushing

• All-metal drive train for consistent operating characteristics at high or low temperatures

• Most EN catalog listings are MIL-PRF-8805 compliant for stringent military and non-military applications

• MIL-PRF-8805 symbol 4 (resilient) sealing to keep dust, water, and ice from entering the switch enclosure

• Gold-bifurcated, gold-plated, or silver-alloy switch contacts for reliably controlling electrical loads from less than 0.5 A [low energy/logic level] up to 15 A (power duty)

• Wide temperature range from -54 °C to 125 °C [-65 °F to 257 °F] for sea level or high altitude military or commercial applications

• Assortment of switch actuators and electrical terminations

• Miniature package size [400EN Series and 600EN Series] reduces housing diameter by 30 % for smaller space required on equipment
 

POTENTIAL APPLICATIONS

• Landing gear systems for commercial and military aircraft including helicopters

- WOW switch (Weight-on-Wheels) for landing gear

- Up-lock and down-lock sensing

- Landing gear bay doors closed/locked

• External doors and hatches for commercial and military aircraft including helicopters

- Closed and locked indication for passenger entry/exit doors, cargo bay doors, and/or other doors or hatches (refueling door, APU air inlet door)

• Military ground vehicles

- Doors or hatches closed/locked or open

• Off-road construction equipment

- Doors or panels present/closed/open

- Up-stop or down-stop limits
