Featured Product: Cooltron High Performance DC Fans

Cooltron's new high performance DC fans feature a reinforced core structure with metal tubes. Designed especially for high end applications such as cloud servers, these fans deliver a much higher airflow and static pressure than a standard DC fan of equal size. This new performance line is available in various case sizes with 12, 24 or 48 Voltages.

High performance DC fans can deliver up to 52% more airflow and 263% more static pressure.  Call your Competitive Components account representative today.  Mention our blog for a special discount on Cooltron fans.  Competitive Components is an authorized distributor of Cooltron Fans.

Think Competitive Components for Amphenol, ITT/Cannon BNC and Mil-Spec Connector Kits

Amphenol and ITT/Cannon are two leading manufacturers of BNC and mil-spec connectors.  The BNC connector (Bayonet Neill-Concelman connector) is a common type of RF connector used for the coaxial cable.  Amphenol's MS connectors meet the latest performance requirements of MIL-DTL-5015.  MIL-DTL-5015 features threaded couplings and single key/keyway polarization, representing maximum simplicity
Competitive Components Inc provides kitting for many different industries.  In fact, CCI stocks several Amphenol and ITT/Cannon connectors for our kitting customers.  View the following list for our commonly stocked Amphenol connectors.

Mechanical Relays - A Guide on How a Relay Works

A relay is a simple electromechanical switch made up of an electromagnet and a set of contacts.  Relays are found hidden in all sorts of devices.  In fact, some of the first computers ever built used relays to implement Boolean gates.

What Makes Up A Relay?

• Electromagnet
• Armature (that can be attracted by the electromagnet)
• Spring
• Set of Electrical contacts

A relay consists of a coil of wire wrapped around an iron core.  Then electricity is applied to the coil of wire, it becomes magnetic, hence the term electromagnetic.  Another type of relay called a solenoid.  The solenoid electromagnet consists of wire wrapped around a tube containing an iron cylinder called a "plunger"  Then electricity is supplied to the wire coil, the "plunger" moves through the tube and activates a switch.

A relay consists of two separate and completely independent circuits.  The first drives the electromagnet.  In this circuit, a switch can control power to the electromagnet.  When the switch is on, the electromagnet is on and attracts the armature.  The armature acts as a switch in the second circuit.  When the electromagnet is energized, the armature completes the second circuit (which will electrify a light bulb at the end of the circuit).  When the electromagnet is not energized, the spring pulls the armature away and the circuit is not complete.  As a result, the light bulb at the end of the second circuit is not electrified.

The following variables must be considered when purchasing or designing-in relays.

• The voltage and current that is needed to activate the armature
• The maximum voltage and current that can run through the armature and the armature contacts.
• The number of armatures (typically one or two)
• The number of contacts for the armature (generally one or two)
• Whether the contacts (if only one contact is provided) is normally open (NO) or normally closed (NC)

In general, relays are used in cases where a small amount of power in the electromagnet to move an armature that is able to switch a much larger amount of power.  For example, you might want the electromagnet to energize using 5 volts and 50 milliamps while the armature can support 120V AC at 2 amps.  In places where a large amount of power needs to be switched, relays are often cascaded.  In this case, a small relay switches the power needed to drive a much larger relay.  The second relay switches the power to drive the load.

Relays are commonplace in every home kitchen appliance to turn on and off a motor or a light.  Relays are also common in vehicles where the 12V supply voltage needs a large amount of current.

Think Competitive Components for board level connectors - AMP/Tyco Electronics/TE Connectivity

AMP has a well-known brand name in the elecctronic components industry.  Over the past few years, they have changed the name from AMP to Tyco Electronics to now TE Connectivity.  Competitive Components offers a service known as kitting.  Kitting means supplying all the parts on a PC board in one package and one purchase order.  This saves time and in time - money.  Because Competitive Components supplies all parts on a PC board, this includes AMP connectors.  We do stock some AMP connectors for customers.  In addition, Competitive Components can offer alternatives to the AMP connectors to one of our authorizes manufacturers like On-Shore Technology and Major League Electronics.

Below is a list of AMP products Competitive Components currently has available in stock.  If we do not have it in stock, have us quote anyway due to our consolidated buying power.  Contact your CCI sales representative today and mention our blog to get a discounted price on the AMP connectors listed below.
