MicroModule’s silicone-rubber actuators are designed with an integrated sealing rib that allows it to be sealed into a system during installation. Common silicone sealant or mounting brackets can also be used to create a watertight seal. Once sealed into a system, spills, rain, or humidity will not affect MicroModule’s performance--making it ideal for field service, outdoor, or hose-down environments. RTV silicone sealant can be used as a sealing material. Be sure to clean the panel and rubber keypad thoroughly with isopropyl alcohol. Integrators may also find that some panel/bezel materials will need to be primed with a silicone primer to obtain proper adhesion. To seal MicroModule with silicone sealant, apply a thin bead of sealant to the top of the rubber keypad on the outer edge of the keypad’s sealing rib. Minimize the amount of sealant applied to prevent lumping near the active buttons, which could adversely affect the MicroModule’s performance. Alternately, sealant can be applied around the perimeter of the module and the bolt holes after it has been mounted into the bezel or panel. For the best possible seal, apply the sealant to both the top of the keypad before installation and around the perimeter of the module after installation.
