The Optima OP-900 stainless replacement cable is a 15-foot, 5-pin-to-bare-wire cable for compatible OP-900A, OP-900B, LP7510, and related indicator installations.
Its stainless connector wording makes it especially relevant to buyers repairing scales in food, agricultural, industrial, and other demanding environments, although the environmental rating of the entire installed system must still be confirmed.
What Is the OP-410-SS Cable?
The MNM listing identifies SKU OP-410-SS as a 15-foot replacement lead with a 5-pin round female connector and bare wires at the opposite end. It is described for compatible Optima OP-900A, OP-900B, and LP7510 readouts connected to a platform, base, or summing junction box. Related OP-901, OP-902, and LP7515 systems may use similar-looking cables, so exact compatibility remains essential.
Where a Stainless Connector Cable Helps
Food processing, meat, seafood, produce, and washdown-adjacent weighing areas.
Agricultural, livestock, feed, and outdoor-covered scale installations.
Industrial floor and platform scales exposed to abrasion, impact, dust, and repeated cleaning.
Maintenance and scale-service work where corrosion resistance at the connector is desirable.
Custom load-cell systems requiring a 15-foot hardwired run from junction box to indicator.
Stainless Does Not Automatically Mean Waterproof
A stainless connector can improve durability and corrosion resistance, but it does not make every connector joint, cable gland, indicator, junction box, or splice submersible. Follow the equipment’s IP rating and cleaning instructions. Avoid directing high-pressure water at unverified connections, and inspect seals before returning the scale to service.
Compatibility and Installation Checklist
Confirm the exact indicator model and that it uses the specified 5-pin female connector.
Compare connector keying, thread, diameter, pin arrangement, cable length, and bare-wire termination.
Wire the junction-box end using the correct schematic; do not assume colors match the old cable.
Use strain relief and route away from cleaning equipment, traffic, sharp edges, heat, and electrical interference.
Test zero, repeatability, corners, span, and communications after installation.
Frequently Asked Questions
Does OP-410-SS fit every OP-900 indicator?
Confirm the exact OP-900A or OP-900B connector revision and wiring. Model-family names alone are not enough to prove compatibility.
Can this cable be pressure washed?
Do not assume so. Cleaning limits depend on the complete installed assembly, including connector seal, indicator, junction box, cable entry, and power components.
When should a cable be replaced?
Replace it when testing confirms open or intermittent conductors, damaged shielding, corrosion, crushed insulation, unreliable connector contact, or repair damage that cannot be safely sealed.
