Tips: How to select the protection form for stepper motor linear actuator
It is necessary to select the appropriate protection form for stepper motor linear actuator according to different environment, in order to prevent the damage to the stepper motor linear actuator caused by the surrounding environment and substances or the disaster caused by the stepper motor failure. The protection forms of the stepper motor are open type, protective type, explosion proof type and closed type. We should follow the following principles in selection.

The open type stepper motor can only be used in dry and clean environment.
The protective stepper motor linear actuator is suitable for dry environment with no dust, explosive and corrosive gas. This kind of stepper motor linear actuator can be selected in such circumstance because they are well-ventilated.
The explosion proof type stepper motor linear actuator can be applied in the environment of explosion danger (such as in the pit of gassy mine).
The closed type stepper motor linear actuator can be divided into self-cooled type, non self-cooled type and sealed type. The former two type can be used in wet environment with corrosive dust and weathering. The latter is applied in the equipment dipped in water (such as submerged pump).

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
