The multistage technique has proven to be the most cost effective and reliable method for protecting sensitive electronic equipment. Employing state-of-the-art avalanche junction diode technology, these devices provide superior performance for video, Ethernet, Token Ring or other LAN interface systems. They are in-line modules with easy interconnecting terminals. A completely enclosed aluminum housing provides EMC shielding to meet industry standard requirements. The enclosure has two female BNC type connections for easy installation. The case is ground for those installations that require external ground connections.

The device was subjected to a 2000A, 8/20s impulse waveform in accordance with ANSI C62.36. The CX12 has an operating frequency range up to 10MHz and the CX12LC up to 100MHz. Figure 3 shows a comparison of capacitance between a industrial standard device (Top Line) and the ProTek Device CX12LC (Bottom Line). Due to the drastic change in the capacitance of the product (Top Line), signal distortion, loss of data or even access into the computer may be a problem. 05017.R2 7/02 1 www.protekdevices.com CX12 and CX12LC DEVICE CHARACTERISTICS MAXIMUM RATINGS @ 25C Peak Operating Line Voltage (V OP ) Operating Line Current (I O ) Maximum Transient Voltage Maximum Transient Current Maximum Leakage Current CX12 Frequency Responce -3 dB CX12LC Frequency Responce -3 dB Operating & Storage Temperature Response Time 12 V 200mA 20kV 3000A (8/20s) 5A @ 30MHz @ 200MHz -40 to +85C < 10 ns ELECTRICAL CHARACTERISTICS @ 25C MAXIMUM CLAMPING VOLTAGE MAXIMUM LINE THRUPUT RESISTANCE R TYPICAL CAPACITANCE @ 0 V, 1 MHz C PROTEK PART NUMBER * Line-Ground 500A @ 8/20 ms VC VOLTS OHMS 3 10 pF 200 25 CX12 CX12LC 24 28 * Other Voltages Available Consult Factory Frequency Responce CX12 1.21" (30.73 mm) 1.10" (27.94 mm) 1.40" (35.56 mm) 1.10" (27.54 mm) Frequency Responce CX12LC 0.15" (3.81mm) 0.72" (18.29 mm) EQUIPMENT INST ALLA TION The CX12 series is designed with a female BNC type connector on both ends for easy installation. Disconnect the video or data line from the sensitive equipment. Insert the CX12 in the line near the AC power outlet of the equipment to be protected. Install a cable in between the CX12 and the equipment to be protected. Attach a ground wire between the case of the CX12 and the equipment AC power ground, or to the coax shield as required. 0.72" (18.29 mm) 0.70"(17.78 mm) 05017.R2 7/02 2 www.protekdevices.com LINE CAUTION: Mounting plate must be CAUTION:Mounting plate must connected earth ground be connected toto earth ground CX12 COAXIAL LINE PROTECTOR CX 12 - COAXIAL LINE PROTECTOR 0.150" DIA.
