Locking systems for hoods and housings

The locking mechanisms of hoods and housings do not only protect the connector from unintentional openings, they also increase the tightness. The most often used locking mechanism for industrial connectors are locking levers. However, there are several mechanisms available in different versions, each of which has its advantages and is suitable for special applications.

  • Easy handling: simply press yellow push buttons simultaneously to lock with an audible click; only one hand needed to lock/unlock

  • Protected against vibration, shock and unintentional opening: turning yellow button by 90 degrees prevents accidental disconnects. Optionally available with additional blocking function

  • Compact design

Han® PushPull locking system


  • The inner, circular locking profile guarantees a self-locking, durable and tightly sealed (IP67) device connection

  • Easy-to-handle: locking mechanism is intuitively plugged with an audible click, unplugged by simply pulling out the connector after having released the interlock ring

  • Device connector, occupying very little space
