Molex claims first SMT potting connector system

By Alex Pluemer, contributing writer

Molex claims the industry’s first SMT potting wire-to-board connector system with the introduction of the Spot-On 1.5 and 2.0 . Molex believes that the new potting system will provide increased processing capability and mechanical reliability in home appliances such as washer/dryers, stoves, and air conditioners.

The Spot-On connector system utilizes SMT-type potting connectors in conjunction with center PCB nails to absorb the stress caused by temperature fluctuation during operation, thereby reducing cracking in the soldering. A potting sealant protects against water damage while the potential for latch failure is diminished by an inner positive lock design.

Automated SMT mounting tails on each Spot-On connector save time and effort during assembly, and a polarized, color-coded receptacle housing simplifies the wire-mating process. All single-row and double-row connectors also feature a retainer for more secure insertion of the crimped terminal.

The Spot-On Connector System provides 1.0 to 3.0 A of current and up to 36 available circuits, and the 1.50-mm and 2.00-mm pitch make it smaller and more space-efficient than its predecessors.
