Frequently asked questions
Does this assembly replace standard OEM parts directly?
Yes, this RPI CAS041 assembly is engineered as a direct replacement for Clay Adams (Becton Dickinson) OEM parts. It is fully compatible with the following OEM reference numbers:
- 421454
- 42059106
- 0591-602-101
Is the electrical rating suitable for heavy-duty use?
Absolutely. The switch is robustly rated for 10.1A at 125/250VAC, ensuring it can handle the specific power requirements of Readacrit and MP Readacrit centrifuges reliably.
Does this include all necessary components for installation?
Yes, it is a complete, ready-to-install assembly. Each unit comes with:
- The momentary (On/Off) switch itself
- A pre-attached insulator for safety
- 15-inch long wires for flexible internal routing
Is this compatible with the newer latch systems?
Yes, this specific assembly is precision-engineered to integrate seamlessly with the New Style Catch Block and Latch mechanism found in compatible centrifuge models.
What is the contact configuration of this safety switch?
This component features a Single Pole, Single Throw (SPST) circuit design with Normally Open (N.O.) contacts, ensuring the safety interlock functions exactly as required by the manufacturer’s original specifications.
How is this safety switch protected against electrical shorts?
The assembly includes an integrated insulator specifically designed to shield the electrical components, preventing shorts and ensuring safe operation when mounted inside the centrifuge’s catch block housing.
Are the included wires long enough for mounting?
The assembly is provided with 15-inch leads, which offer ample length for standard installation procedures inside the centrifuge catch block, allowing for a clean and manageable fit.
Is this a genuine replacement part for my centrifuge?
RPI parts are high-quality, factory-new components designed to meet or exceed OEM specifications. This switch is specifically built to restore the proper functionality of the safety interlock system in your Clay Adams Readacrit or MP Readacrit centrifuge.
Is this a momentary switch or a permanent toggle?
This component is strictly a momentary (On/Off) switch. This is crucial for centrifuge safety, as it ensures the device only operates when the catch block is properly engaged.
Is this component suitable for routine maintenance repairs?
Yes, it is a perfect choice for preventative maintenance or repair scenarios. As a factory-new assembly, it eliminates the need to source individual wires or insulators, providing a streamlined solution for servicing your laboratory equipment.
