Micro Power Distribution Box (μPDB) Sealed Modules

Molex µPDB modules are fully sealed with an IP67 NEMA rating and are available in standard and customizable versions

Image of Molex's Micro Power Distribution Box (μPDB) Sealed Module Molex MicroPDB (µPDB) sealed modules are compact automotive power distribution boxes that provide a junction point for power switching and circuit protection for vehicles or subsystems within wiring architectures. This connectorized system attaches simply and inexpensively to the vehicle and reduces the amount of cut leads needed compared to traditional auxiliary boxes. MicroPDB modules can be mounted in multiple locations within the vehicle and eliminate hardwiring as well as the accompanying costs and potential errors. These modules deliver reliability and are fully sealed with an IP67 NEMA rating. They meet USCAR-2 criteria and are offered in standard and customizable versions with an operating temperature range of -40°C to +110°C and switching voltage options of 12 V or 24 V.
