L Series Contactor

L Series contactors are hermetically sealed, non latching switching devices rated for 90 amps in both AC and DC configurations. They’re perfect for both military and commercial aircraft applications. Special models with auxiliary contacts are available.

This contactor is specially designed to meet MIL-PRF-6106 standards.

  • 50,000 minimum operating cycles at resistive load
  • 100,000 minimum operating cycles at 25% resistive load
