        U-shaped fork open metal lug NTC temperature sensor. The front end is integrally stamped stainless steel U fork lug. The open structure can be directly clipped into bolts for fast locking without removing nuts for easy installation. Built-in NTC thermistor temperature measuring element, the metal lug fits the metal heating surface with large contact area, fast heat conduction and sensitive temperature response. The wire adopts black high temperature resistant PVC insulated cable, with tinned bare wire at the end for customers to solder directly to PCB circuit boards. Standard electrical parameters: 10K resistance at 25℃, B value 3950, tolerance optional 1%/3%/5%. Standard stock wire lengths are 0.5m/1m. Full parameter OEM customization including fork opening size, wire length, resistance and B value is supported, suitable for rapid temperature measurement on metal surfaces of frequency converters, motors, power modules and energy storage equipment.

Q1：U 型叉形开口耳片探头相比圆孔耳片有什么结构优势？
U 型开口叉耳为开放式结构，安装时无需完全拧下设备固定螺栓、螺母，直接将叉口卡入螺杆后拧紧螺母即可完成固定，拆装检修效率更高；一体冲压不锈钢材质平整度高，贴合金属发热面无导热空隙；金属防锈耐腐蚀，适配工业油雾、潮湿工况；套管与叉耳压合加固，反复弯折不易开裂断线。
What structural advantages does the U-shaped fork open lug probe have compared with round hole lugs?
The U-shaped open fork lug adopts an open structure. During installation, there is no need to completely unscrew the equipment fixing bolts and nuts. Just clip the fork opening into the screw rod and tighten the nut to complete fixation, with higher disassembly and maintenance efficiency. The integrally stamped stainless steel has high flatness, fitting tightly to metal heating surfaces without heat transfer gaps. The metal material is rust and corrosion resistant, suitable for industrial environments with oil mist and humidity. The crimp joint between sleeve and fork lug is reinforced to prevent cracking and wire breakage after repeated bending.

Q2：线材与出线末端支持哪些定制规格？
线材统一黑色耐温 PVC 护套，长期耐温区间 - 20℃~105℃；末端标准为裸线镀锡，无塑胶端子，可按需更换 XH/PH/ZH 系列塑胶端子、杜邦插头；现货常备线长 0.5m/1m，0.3m~3m 任意总长、铜丝粗细线芯均可定制；护套可改白色、灰色等其他绝缘配色。
What customizable specifications are supported for wires and wire ends?
All wires are covered with black high temperature resistant PVC jacket with long-term temperature resistance from -20℃ to 105℃. The standard wire end is tinned bare wire without plastic terminals, which can be replaced with XH/PH/ZH series plastic terminals or DuPont plugs as required. Standard stock wire lengths include 0.5m/1m, any total length from 0.3m to 3m and copper wire core thickness can be customized. The jacket color can be changed to white, gray and other insulating colors.
