Mindray D3 Defibrillator Encoder Assembly 50KST45-01-1-08N-F Including Wiring C76884-B

Product Introduction

The encoder assembly (part number 50KST45-01-1-08N-F) with its accompanying wiring harness (C76884-B) is the rotary control unit found on the front panel of the Mindray BeneHeart D3 defibrillator/monitor. It's the knob you turn to select energy levels, switch between operating modes, and adjust various parameters during patient care.The wiring harness, C76884‑B, is the dedicated signal cable that connects this encoder to the D3's main control board.

Advantages

1. Mode selection at a twist. Turning the encoder lets you switch between the D3 four main operating modes. Monitoring, Manual Defib, AED, and Pacing without any hesitation or stutter. In a code situation, that kind of smooth, positive engagement matters.

2. Energy adjustment with precision. When you're in manual defib mode, the encoder lets you dial in energy from 1J all the way up to 360J in precise steps. In pacing mode, it adjusts the pacing rate and output current to suit adult or paediatric patients. The design is incremental and photoelectric every 3° of rotation generates a pulse, and the encoder's response frequency hits 1 kHz, so even rapid adjustments don't get dropped or misinterpreted.

3. Parameter fine tuning. Outside of defib and pacing, the encoder handles ECG lead selection, alarm threshold adjustments, and waveform speed settings. In AED mode, it helps confirm that the rescue parameters are set correctly before the shock is delivered.

Keep in Mind

• Use only genuine Mindray parts. The manufacturer states that using non‑approved parts may void the warranty and could compromise device safety and performance.

• Handle the encoder gently. The Grayhill encoder is rated for 25,000 mechanical cycles, but that's under normal use,not abuse. Avoid forcing the knob past its stops, and don't use excessive torque when tightening the panel nut.

• Protect the harness during service. The C76884‑B cable uses medical grade shielding damage to the shielding can compromise signal integrity. When routing the cable, avoid sharp bends, kinks, or pinching it between panels. The cable is designed to withstand the flexing that comes with device movement, but it's not indestructible.
