A transit case uses isolating mounts to protect electronic payloads from vibration. These mounts are chosen with a natural frequency of vibration significantly different from the expected excitation frequency. This helps ensure the minimum of vibration is transmitted to the payload. However, there are challenges: Continue reading →

Vibration is bad for electronic devices such as radio transmitters and computers. Screws can work loose and cards and cables can come unplugged. As a result, equipment is sometimes inoperable after a long journey. Fortunately, that kind of damage is usually easily repaired, unlike the harm caused by resonance. Continue reading →

Electronic systems need transporting with care. Sudden impacts, as if dropped from the back of a truck, can pop IO cards out of their slots, disconnect cables, and damage hard drives. That’s why you’ll often see acceleration or g-force limits called-out in specification documents for many electronic products. Continue reading →

Something first-time transit case buyers often overlook is adding an I/O panel for easy cable connection. Without it, the case is little more than a storage box, albeit one providing protection from temperature extremes, dust, humidity and shock impact. Using the equipment inside means either taking it out of the case or running with the case open and cables fed in. Either option negates the purpose of the case. Continue reading →

Installing electrical equipment in rack mount cases can challenge the most dexterous technician. The usual procedure is to make the connections at the rear before mounting the unit in the rack. Inevitably though, the cables bunch up behind the equipment, stopping it from sliding into place. A second pair of hands is then needed to gently draw out the cables while at the same time, the hardware is pushed home. Only then, can the securing screws be inserted and tightened.  Then the cables are rearranged, if there’s room to get a hand between case and equipment. Continue reading →

When warm air meets a cold glass of beer, condensation forms on the surface. The resulting drips may be annoying, but they won’t ruin your beer. Should condensation occur inside a transit case, it’s another story. Continue reading →
