The 09140034501 is a 3-contact Han Pneumatic Module for Ø1, 6/3/4mm, male and female. The Han® Pneumatic module shall be used to transmit properly prepared compressed air in the vicinity of Han-Modular® connectors. It is suitable for use in pneumatic systems which have an operating pressure no greater than 8 bar. The female contacts are available in versions with or without the shut-off function. In the shut-off version, a spring-loaded valve closes over an O-ring when the connector is opened. This prevents compressed air from escaping. When plugged in, the male contact presses against the valve and keeps the contact open.
