Ferrogard GD2 Non-contact Interlock Switches

The Ferrogard™ GD2 Non-contact Interlock Switch has a stainless steel housing for added protection against inadvertent impacts to the housing. The contacts are completely sealed to meet IP68 (NEMA 6P) requirements, making them ideal for wet environments. The GD2 also has a wider temperature range than the plastic Ferrogard switches, making them useful in a wider range of applications.
