ESD Guns has acquired an NSG 439 and is offering it at a substantially discounted rate from MSRP. The chassis of the discharge pistol is designed for a mounted use on a robot, but is equivalent to the Teseq NSG 438 in every other way. 

This will be suitable for robotic applications, or track mount applications performing vertical air discharge. Alternatively, a handle can be fabricated and can be used as a pistol comparable to it's NSG 438 sister model.

Teseq NSG 439 Overview:

Today’s growing trend towards miniaturizing and more comprehensive product standards means that ESD testing is now required not only for operating controls, but also for any associated peripheral devices such as sensors, actuators and controllers. Many of these devices have multi-pin connectors with high pin counts. In order to meet space restrictions, these pins are often arranged close together.

However, conventional air-discharge testing of these closely spaced pins is problematic because the airdischarge arc may jump to an adjacent pin instead of the pin intended for test. With an innovative robotic air-discharge adapter accessory, Teseq provides a tool which will prevent unintentional discharge paths. Furthermore, the approach speed, which is crucial for reliable air-discharge testing, can be programmed as a constant.

ESD testing of connectors often requires that each individual pin is tested for an extensive range of conditions including multiple discharges, polarities, voltage settings, and even R/C networks. Connector testing can take many hours or even days of monotonous, precise effort to complete. As a result, when this testing is done manually it is prone to errors. The advantage of robotic testing is that these procedures can be automated and precisely executed, ensuring a level of repeatability that cannot be achieved with manual testing.
