About Us

In 1978, Derek McNally founded a manufacturers representative firm. Incorporated soon after as DJM Electronics, the company originally concentrated on electromagnetic component lines, but soon moved into the capital equipment market. Driven by the military's focus on RF shielding and electromagnetic compatibility (EMC), DJM Electronics established a strong relationship with one of the leading RF shielding companies of the day -- Lectro Magnetics, Inc. in Los Angeles -- and proceeded to develop a complete EMC product line offering.

For the next two and a half decades, DJM Electronics worked with nearly every RF shielding company and EMC equipment manufacturer in North America. Some companies went out of business, others were bought, but the people in the industry remained largely the same. DJM Electronics' longevity and active participation in local organizations and events gave the company a reputation for honesty and integrity and earned it a position as one of the pillars of the close-knit EMC industry.

In 2002, DJM Electronics utilized its network of friends and associates to develop new lines of business -- first buying and selling used shielded rooms; then, distributing shielding materials for assembly by others; and eventually, designing and manufacturing high speed digital signal filters.

Today, DJM Electronics is one of the largest manufacturers and distributors of EMI filters, RF shielding products, RF absorber and shielding accessories in North America. With our patented filter technology, we offer the only 100dB filters available for high speed digital signals. Whether you need Fast Ethernet, Gigabit Ethernet or USB 2.0 in your shielded enclosure, we have the solution for you.

Our goal is to provide our customers with high grade EMI filters and shielding solutions at a fair price.

Thank you for considering DJM Electronics.
