Box dimensions: height 2.2 in.; width 4.6 in.; depth 3.6 in.
The CR-150-BOX is an unpainted die-cast aluminum housing for the CR-150 evaluation test board (see the application guide for the CR-150 for more details). Using the CR-150-BOX will simply the task of electrically shielding the CR-150 evaluation test board and the associated charge sensitive preamplifier (CSP). Holes have been positioned on the CR-150-BOX in locations associated with BNC connector positions (detector bias, preamplifier output, and test pulser input) and banana connector positions (-12V, GND, +12V) on the CR-150 board. There is also a hole on the opposite side of the box to apply a ’panel-mount’ coaxial connector, which can be connected to the input (detector) terminal of the CR-150 board via a soldered wire connection. A panel mount BNC connector is supplied for this purpose.
The PCB-mounted connectors on the CR-150 board do not make electrical connection to the CR-150-BOX aluminum housing. This connection can be made through the ground connection between the "input" BNC connector and the CR-150 board (see below). In the event the input BNC connector is not used in your application, this important connection between the CR-150 board and the aluminum housing should still be made.
