Shock and Vibe!

COTSWORKS performs harsh environmental testing including Humidity, Shock, Vibration, and EMI performance to industry standard and customer specific needs. Our RJ, RCP, and SFF products have a standard set of reports available and our cable and termini products also have a standard set including items such twist and pull strength. Products also have standard reliability reports such as MIL 217.  

Test procedure for vibration in accordance with MIL-STD-1344A

Shock and Vibe table

The test was conducted in accordance with the MIL-STD-1344A test standard Condition IV (Modified for 1 cycle only). The RJs were attached to a COTSWORKS supplied holding fixture, which in turn, was rigidly attached to the moving element of the vibration machine. The RJs (while in un-powered mode) were then subjected to the following vibration applied in each of three mutually perpendicular axes: a sine vibration swept logarithmically from 10Hz to 2000Hz and back to 10Hz in 20 minutes. The input level throughout the sweep was the lesser of 0.06-inches double amplitude or 20g. The vibration was applied for one sweep cycle per axis.

Test procedure for mechanical shock in accordance with MIL-STD883H

The test was conducted in accordance with the MIL-STD883H test standard Method 2002.5 Condition B. The RJs were attached to a COTSWORKS supplied fixture, which in turn, was rigidly attached to the moving element of a Mechanical Shock machine. The RJs were subjected to five shock pulses in each direction of three mutually perpendicular axes, for a total of thirty shocks. Each shock pulse had a half sine waveform with amplitude of 1500 Gs. The duration of each shock pulse was 0.5 milliseconds. The RJs were in powered mode and monitored throughout the exposure.
