These components are similar in principle to the electrical connectors found in control panels and used to rationalize cabling and trouble shooting.
Used alongside electrical connectors Legris DIN rail connectors provide similar facilities for pneumatic pipework, and are mounted on the same rail profile which allows electrics and pneumatics to run side by side. All tube connections are Legris push-to-connect fittings for plastic tubing.
Channels or slots for labels are found on the front of these connectors which allows air lines to be coded and identified to assist in trouble shooting.
Test point facility
Being able to detect the presence of air is an important consideration when maintaining pneumatic control systems. Legris DIN rail connectors incorporate test points which pop out after being manually depressed, indicating the presence of air in the pipe.
