A line of electrical connectors has been expanded to include more configurations, and designs with 20 (HG3), 34 (HG4), or 85 (HG6) pin positions. The connectors from Hypertronics Corp., Hudson, Mass., (www.hypertronics.com) are aimed at the medical industry. HyperGrip is a user-configurable circular connector, that is also color-coded and customer-keyable for accurate and quick connections. Keying lets users build connectors with six different keying options from a set of common components, thereby reducing cost, lead-time and inventory.
