Y connection cables feature a male connection to two female connections. They are used for the connection of two sensors or actuators to a splitter box and module. The connections of sensors and Y distributors guarantee a perfect lasting seal even when fastened by hand. The integrated end stop protects the O-ring against destruction caused by over-tightening the nut. Even in harsh industrial environments, the connectors are protected against unintended loosening by a special vibration protection. Some types are fitted with highly visible LEDs for operation and switching status indication.
