The A5251 adapter is compliant with A5202/DT5202 and A5204/DT5204 boards. It mechanically adapts from the input edge card connector (type HSEC8โ170) to a couple of Samtec SS4โ40โ3.0โL-D-KโTR connectors. The adapter is suited for biasing and reading out an 8ร8 Hamamatsu S13361โ3050AEโ08 SiPM matrix. The A5251 is also equipped with a TMP37 temperature sensor. A dark plastic box is also included in the delivered kit, which is ideal for shielding environmental light and pulsing the matrix via the fiber optic connector placed on top of it.
