Mindray D3 Defibrillator Mainboard To Keypad Wiring Harness C76870-A Internal Ribbon Cable Replacement

• Product Description

This is a internal connection cable specifically designed for the Mindray D3 Defibrillator. Identified by the part number C76870-A, this component serves as the critical communication bridge between the device's main motherboard and the front control keypad assembly. Visually, it features a durable black flexible flat cable (FFC) reinforced with a beige protective insulation layer in the center to prevent signal interference and physical wear. Both ends are equipped with precision-molded black ZIF connectors that ensure a secure lock into the circuit board sockets. Functionally, this wiring harness is responsible for transmitting vital user inputs—such as energy selection, charge, and shock commands—from the external buttons to the main processing unit. It may also carry data signals for LED indicators on the control panel. Replacing a worn or damaged cable with this unit restores full operational responsiveness to the defibrillator's interface.

• Product Specifications

• The function of the product

The primary function of the C76870-A wiring harness is to act as the data highway for the user interface. It translates physical button presses on the exterior of the Mindray D3 into digital signals the mainboard can process, enabling the operator to control charging cycles, select joules, and initiate shocks safely.

Use tips

• 1. Handle with Care: Do not fold or sharply crease the cable, especially the beige reinforced area, as this can break internal traces.
• 2. Connector Safety: Do not force the cable into the socket. If it doesn't fit, check the alignment. Forcing it can damage the delicate pins inside the connector.
• 3. Static Protection: Use an anti-static wrist strap when handling internal electronic components to prevent ESD damage.
