Frequently Asked Questions about D-Subminiature Products
A gender changer is an interconnect device with the same gender connector on both sides. A gender changer allows two cable assemblies with the same gender connectors to mate.
A jumper wire is typically a short wire used to electrically connect two or more positions within a connector.
These terms mean the cable assembly or adapter is wired with each conductor connected to the same connector position on each side of the assembly.
PVC (PolyVinyl Chloride) has good insulation qualities, is cost effective, and is easy to work with.
The drain wire and cable braid are both part of a cable shield and are electrically connected. A drain wire is used to ease termination of the cable shield for crimping or soldering.
Fully populated means all connector positions of a cable assembly are connected to a conductor.
The distance from centre to centre between neighboring contacts.
Electromechanical coupling device that provides an electrical interface that can be mated and unmated.
Connectors replace the need to "hard wire" connections. Advantages of using connectors are: - ease of manufacture (plug and play); - ease of repair; - ease of upgrades.
A shielded cable or adapter has a conductive material over the conductors that provides protection against EMI (electromagnetic interference) and RFI (Radio Frequency Interference).
A device that is said to be a Panel Mount such as a cable assembly or adapter can be attached to a cut out in a panel, box, or frame.
An insertion/extraction tool aids in inserting or removing a contact from a connector. It is used to fix wiring mistakes or update an assembly to a new wiring scheme.
The CSM series of cables are pass through cables. However, if you are mounting these you may be better off using our CRMN series. This series is made specifically for panel mounting.
What is a DB9 Connector?
The term "DB9" refers to a common connector type, one of the D-Subminiature or D-Sub types of connectors. DB9 has the smallest "footprint" of the D-Subminiature connectors, and houses 9 pins (for the male connector) or 9 holes (for the female connector).
Where are DB9 Connectors used?
DB9 connectors were once very common on PCs and servers. DB9 connectors are designed to work with the EIA/TIA 232 serial interface standard, which determined the function of all nine pins as a standard, so that multiple companies could design them into their products. DB9 connectors were commonly used for serial peripheral devices like keyboards, mice, joysticks, etc. Also they are used on DB9 cable assemblies for data connectivity.
Today, the DB9 has mostly been replaced by more modern interfaces such as USB, PS/2, Firewire, and others. However, there are still many legacy devices that use the DB9 interface for serial communication.
What does L-com carry for DB9 Connectors?
L-com has a huge variety of DB9 products, including DB9 connectors, DB9 adapters, and DB9 cables assemblies.
The diameter of CSMN25MF and CSMN25MM cable assemblies is .305" nominal.
The CS2N9MF cable assemblies have an operating temperature range of 20°C to 75°C. Our CSM, CSMN, and CRMN series of cables have an operating temperature range of 20°C to 80°C.
In most cases the color code is listed on the Engineering Drawing for each item.
Our CSNULL9FF series does not ship with dust caps. However, you can purchase dust caps for the connector ends.
