High Performance Group Relays & Contactors

CII covers DC and AC, ranging from signal level to 50A hermetically sealed relays, otherwise known as “mid-range” product. Included in this category are TO-5 style relays, crystal can relays, time-delay relays, and MIL-qualified product. Hartman provides both DC and AC contactors ranging from 25A to 1000A. Included in this category are 1PST to 3PDT, environmentally seal devices. Kilovac is our specialty brand which covers high voltage DC (HVDC) hermetically sealed relays and contactors. Included in this category are 270Vdc to 70 KVdc devices from a few amps to 1000A. For information on switching load types or other technical queries, please consult customer service, your local Sales Engineer, or Field Application Engineer for details.

Industrial product (P&B, Axicom, and Schrack) will typically have a UL or CSA rating. High-performance product (CII, Hartman, or Kilovac) will be generally screened to a MIL or custom baseline test procedure or qualified to M6106, M83726, or M83536. Industrial products are commonly plastic cased and unsealed. High-performance product are generally hermetically/environmentally sealed with a metal housing. Industrial relays are typically used in appliance, automotive, computer, and/or consumer products. High-performance devices are generally used in medical, aerospace, military, and harsh/high reliability environments.

A mechanical economizer coil is a low current (high resistance) coil that is cut in to hold the contacts closed after a high current (low resistance) pull-in coil transfers the contacts, reducing coil current draw, while the contactor remains energized. As an option, a low-cost method of economizing can be utilized. For example, Kilovac’s EV series contactor uses pulse width modulation (PWM) or electronic economizer. The principal is the same as the mechanical economizer. The PWM can be used in ground applications and generally not used in flight or high reliability applications since it may create EMI issues with sensitive equipment. In either case, the economized coil is a power saver with regards to the hold current.

In short, no. Our high-performance products are not position sensitive and can be securely mounted in any axial direction.  But, it is good to note the vibration and mechanical shock environments where the product will be used. Areas of high vibration or high shock could affect the overall performance of the relay over time. Consult customer service, Sales Engineer, or Field Applications Engineer for guidance.
