一、產品介紹：

    K32HCHJ-LEK-PF-01 信號端口電壓值都較低，在雜亂電氣環境、信號電纜長度較長情況下，以及戶外運用或戶外有金屬構件引入室內的情況下，都要進行浪涌電壓保護，以保護編碼器信號端口不被損壞。
是指在驟變的電磁場變化條件下，信號電纜瞬間感應到較大的浪涌電壓，其經過小于1納秒的時刻反應，以TVS管約束電壓，熱敏電阻阻抗突增而約束電流，氣體放電管導通向地線釋擴大電流能量等三級保護措施，以確保銜接的后續設備不被損壞。而這種驟變的電磁場，往往是由于大電機的發動、信號線離動力線過近、雷擊電流經過避雷針入地、或金屬構件而經過室內而感應獲得。以，即使編碼器在室內運用，有時也需要考慮加裝浪涌保護器。在有些場合下，編碼器浪涌保護器也稱為防雷器。

Product introduction:

K32HCHJ-LEK-PF-01 The voltage value of the signal port is low. In the case of messy electrical environment, long signal cable length, outdoor application or outdoor l components introduced into the room, surge voltage protection shall be carried out to protect the encoder signal port from damage.

It refers to that under the condition of sudden change of electromagnetic field, the signal cable instantly induces a large surge voltage, which reacts for less than 1 nanosecond, restricts the current by restraining the voltage with TVs tube, the sudden increase of thermistor impedance, and the gas discharge tube leads to the ground wire to release expanded current energy, so as to ensure that the connected subsequent equipment will not be damaged. This sudden change of electromagnetic field is often induced by the start of large motor, the signal line is too close to the power line, the lightning current enters the ground through lightning rod, or l components. Therefore, even if the encoder is used indoors, it is sometimes necessary to consider installing surge protector. In some cases, encoder surge protector is also called lightning protector.

Product features:

L surge protection of encoder CANopen signal, RS485 / MODBUS signal and 4-20mA signal.

L the signal bandwidth is 10MHz, the insertion loss is less than 0.5dB, and the influence of encoder signal is minimal.

L the three-level circuit cooperates with protection, the reaction time is less than 1 nanosecond, the discharge current is large, and the service life is long.

L in the complete protection mode, the line to line and each line to ground can accept the maximum 10kA impulse current.

L professional lightning protection skills from Europe. 35mm guide rail device type.
