Force-guided safety relays feature a fail-safe, "active," force-guided contact design that ensures that NO and NC contacts may not be simultaneously closed. Users may specify relays with forced-guided contact sets containing two to 10 contacts in numerous sizes, contact configurations, and materials to match specific applications. The design also includes chambering and electrical separation between logic and load contacts, due to reinforced insulation between the contacts within each contact set.

Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
