SB50 CONNECTOR SET WITH 6 THIMBLE

SB50 CONNECTOR SET WITH 6 THIMBLE

The SB50 CONNECTOR SET WITH 6 THIMBLE is an SB50-style two-pole DC power connector set supplied with six thimble/contact pieces for compatible battery and equipment wiring. Common buyer searches include SB50 connector set, 50A battery connector, two-pole battery plug, forklift battery connector, EV power connector, UPS battery connector and SB50 contacts for high-current DC wiring.

SB-style connectors are widely used as quick-disconnect interfaces in battery systems because the two-pole housing helps keep positive and negative conductors organized within one mating connector. The supplied thimble/contact pieces are part of the electrical connection and must be matched to the conductor size and crimping method used in the finished cable assembly. The current class associated with an SB50 housing should not be treated as a guaranteed harness ampacity without considering the contact, cable, crimp quality, ambient temperature and duty cycle.

Low-resistance connector performance depends on clean mating surfaces, correct contact seating and a sound wire termination. A poor crimp can create more heat than the connector housing itself, especially in battery, inverter and traction-power circuits. Contact pieces should lock fully into the housing and mate with the corresponding connector without excessive force or looseness. Cable strain should be supported so repeated plugging does not transfer bending loads directly to the crimp joint.

For battery packs and mobile equipment, polarity control is critical because a reverse connection can damage electronics or create severe fault current. Use consistent housing orientation and cable color identification across the system. A fuse or breaker selected for the cable and battery design should protect the circuit; the connector is a service interface rather than an overcurrent-protection device.

Match the SB50 connector set by housing style, mating key/orientation, contact size, cable gauge, expected current and required number of contact pieces. If replacing an existing connector, compare the physical housing and contact dimensions directly. Also check cable bend radius and enclosure clearance before crimping the final harness length.

Applications

• Lithium battery pack charge and discharge connectors.

• UPS, inverter and backup-battery quick disconnects.

• EV, e-rickshaw, mobility and industrial DC equipment.

• Battery testing benches and service cables.

• Custom battery harness and power-distribution assemblies.

Installation Guide

Disconnect the battery before crimping or inserting contacts. Verify cable polarity and mark the positive and negative conductors before assembly. Use a crimp tool and contact size that match the selected cable, then pull-test the termination and confirm the contact locks into the housing. Keep exposed contacts separated from tools and conductive surfaces. After mating the connector, inspect it under controlled load for unusual heating, looseness or discoloration.

Why Choose ARB Accessories?

ARB Accessories focuses on lithium-battery, EV, energy-storage and battery-pack assembly components. The catalog brings together BMS boards, connectors, insulation materials, battery wiring, terminals, fuses, enclosures, testing equipment and assembly tools. For battery builders, repair workshops and OEM buyers, sourcing related components from one specialist catalog can make specification matching and procurement easier. Final suitability should still be checked against the exact battery design, equipment model and electrical requirements before installation.
