OPTICAL FIBER OPTICAL FIBER ADAPTER A7412 SOLD SEPARATELY CABLES (Supplied with C8137) POWER SUPPLY UNIT with TEMPERATURE CONTROL C8137 DIRECT INPUT C-MOUNT LENS PHOTONCOUNTING HEAD H16721 SERIES The temperature of the H16721 outer case rises due to the thermoelectric cooler housed in the case. The A7423 heatsink efficiently radiates away this heat to prevent a temperature rise in the H16721. The A7423 can be easily installed onto the H16721 with four M3 screws. Apply a coat of heat conductive grease onto the joint surface shared by the H16721 and A7423. Parameter Input voltage During lock...
