ESL's New M4503 Ruggedized DB9 A/B Manual Switch Qualifies for Nuclear Power Plants

November 15, 2007

FOR IMMEDIATE RELEASE

Electro Standards Laboratories (ESL), Cranston, RI, has just announced the new Model 4503 Miniature DB9 A/B manual network switch, designed to withstand environments subject to vibrations. This data network switch and its feed-through connector have successfully passed the rigorous seismic testing of the EPRI “SQURTS” Program, qualifying it for use in nuclear power plants. Model 4503 is ideal for factory floors, energy facilities, or any other harsh environment.

Model 4503 allows data to pass through all pins of the DB9/F connector interface, and it switches all pins simultaneously. The keylock feature provides “pass-key only” access to switching. Key is captive in “B” position and removable in “A” position. This ruggedized switch has an all aluminum enclosure, specifically designed to be EMI/RFI (interference) resistant in noisy environments. Model 4503 network switch can be securely attached to a panel with optional mounting ears, and is also available as a desktop or rackmount unit.
