Accounting Policies [Abstract]
Reclassification, Comparability Adjustment [Policy Text Block]	Reclassifications - During the fourth quarter of 2019, the Company changed its financial statement presentation of research and development costs. These costs were previously included within cost of sales and were a factor in arriving at gross profit. Research and development costs in the amount of $6.2 million and $20.2 million have been reclassified from cost of sales to a separate line item below gross profit in the accompanying condensed consolidated statements of operations for the three and nine months ended September 30, 2019, respectively. Also during the fourth quarter of 2019, the Company changed its financial statement presentation related to gain/loss on foreign currency exchange. These gains/losses were previously included within selling, general and administrative expense. Gains on foreign currency exchange in the amount of $0.6 million and $0.5 million have been reclassified from selling, general and administrative expense and are now included within other (expense) income, net on the accompanying condensed consolidated statements of operations for the three and nine months ended September 30, 2019, respectively. These changes in presentation are consistent with that of our peers. The Company also implemented a change to its reportable segments during the fourth quarter of 2019. In the past, the Company's reportable operating segments were geographic in nature: North America, Europe and Asia. In connection with the Company's migration to its new ERP system and with the acquisition of CUI, management is now assessing the business on a product group basis, and making decisions based on the profitability of three product segments, Cinch Connectivity Solutions, Power Solutions and Protection, and Magnetic Solutions, in addition to a Corporate segment. The segment disclosures in Note 14 for the three and nine months ended September 30, 2019 have been recast to reflect the new reportable operating segments. All amounts included in the tables to these notes to condensed consolidated financial statements, except per share amounts, are in thousands.

This guidance aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software.

The new guidance will broaden the information that an entity must consider in developing its expected credit loss estimates related to its financial instruments and adds to U.S. GAAP an impairment model that is based on expected losses rather than incurred losses. The amendment is effective for the Company for annual reporting periods beginning after December 15, 2022, with early adoption permitted. Management is currently assessing the impact of ASU 2016-13, but it is not expected to have a material impact on the Company’s consolidated financial statements.

This guidance removes certain disclosures that are not considered cost beneficial, clarifies certain required disclosures and adds additional disclosures. The standard is effective for fiscal years ending after December 15, 2020. The amendments in ASU 2018-14 would need to be applied on a retrospective basis. The Company is currently assessing the impact the new guidance will have on the Company's disclosures. In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes ("ASU 2019-12"), which modifies ASC 740 to reduce complexity while maintaining or improving the usefulness of the information provided to users of financial statements. ASU 2019-12 is effective for the Company for interim and annual reporting periods beginning after December 15, 2020. The Company is currently assessing the impact of ASU 2019-12, but it is not expected to have a material impact on the Company’s consolidated financial statements.
