Serial AC Power Sequencer
90-200-001
Each power outlet can be programmed to switched on in sequence with a specific timing delay. The delay can be staggered to ensure that order dependent systems - like PXI - can be switched on and off in an orderly way with just one operation. A staggered start up also limits the inrush current associated with the powering up of equipment, including earth current inrush, placing less stress on cabling and leakage breakers. Power on or off instructions can be initiated from either the front panel switch or via the serial interface.

AST applies stresses (such as temperature and vibration) to products well beyond its normal use environment. This type of testing is done to determine product operating and destruct limits. These stresses are applied as the product is functionally tested and continuously monitored for failures.Highly Accelerated Stress Testing (HALT) and Highly Accelerated Stress Screening (HASS) are two types of accelerated stress testing. These types of tests are commonly used to eliminate design problems, helping to develop a robust, mature product prior to market introduction. It can also be used to screen out infant mortality issues prior to shipment.

Polyurethane Jacket RF Cable Assemblies
For applications where space is limited and minimizing transferred mechanical stress on the interface connection is a must...The polyurethane jacketed versions of our already proven cable assemblies deliver new engineering options to standard FEP jacketed cables.Polyurethane offers greater memory retention than a similar size cable jacketed with FEP. This feature offers the benefit of minimizing stress and torque applied to interface connections, such as those on a circuit board.It also allows cable to better maintain position in an installation where the "spring back" of an FEP jacketed cable could be problematic.Additionally, a polyurethane jacket offers improved abrasion resistance over an FEP jacket.

ICP® Shock Accelerometers
Piezoelectric ICP® accelerometers afford a very high signal output (+/- 5 volts full scale) and the ease of two-wire electrical connectivity. Their inherent ruggedness enables them to be severely over ranged without damage. The addition of internal mechanical isolation minimizes the high frequency stress that would otherwise be encountered by their ceramic sensing elements. This mechanical isolation, coupled with an internal 2-pole electrical filter, built into the ICP® circuitry, tailors the overall accelerometer response to assure data quality to frequencies as high as 10 kHz. Depending on the specific model, accelerations in excess of 50 kg can be successfully measured. These modern designs, with their internal elastomeric isolation materials are verified through calibration to remain dynamically linear and are enabling piezoelectric accelerometers to operate in increasingly severe acceleration environments.

Tin Whisker Testing
Tin whiskers pose a serious problem for electronics of all types. When used as a finish material for electronic components, pure tin can spontaneously grow conductive whiskers. These structures can form electrical paths, affecting the operation of the subject device. The scientific community has yet to agree on the reason for tin whisker growth. Some theories suggest that tin whiskers might occur due to a mechanism of stress relief, especially “compressive” stress, within the tin plating.

Tension & Compression Load Cells
Procter & Chester Measurements Ltd
Tension and compression occurs when a tensile stress is applied, then transforms to a compressive stress, or vice versa. The stress will go through the zero point were no stress is applied. The load cell will operate in tension only, compression only or tension and compression modes. This style of load cell can lead to more flexibility in future testing.
