This economical turnstile is ideal for low to medium traffic installations. It can be used for two way traffic in a mechanical operation, or one way traffic in an electrical access control operation. Turnstiles are capable of counting persons passing through.
An electrical cable consisting of an inner conductor surrounded by an insulating spacer, surrounded by an outer cylindrical conductor. They are often used for Closed Circuit Television because they provide low signal loss.
Glass fibers are used instead of metal wires because signals travel along them with less loss, and they are immune to elecromagnetic interference. Fiber is widely used in data communication, because it permits transmission over longer distances and at higher data rates than other forms of communications.
Wiring in which two conductors (two halves of a single circuit) are wound together for the purposes of canceling out electromagnetic interferience from external sources.
Commonly known as Cat 5 or Cat 6 is a twisted pair cable type designed for high signal integrity. This type of cable is often used in structured cabling for computer networks such as Ethernet, and is also used to carry many other signals.
