HOUSING (SB350 BLUE)
Frequently Asked Questions
Q: What is the AN-244 housing and what equipment does it fit?
A: The AN-244 is a blue housing for SB350 multipole power connectors. SB350 connectors are larger-amperage rated connectors used on electric pallet jacks, forklifts, and walkie stackers from Crown, Toyota, Raymond, Yale, Hyster, and similar manufacturers. Verify your equipment uses SB350 connectors before ordering.
Q: Why is the AN-244 blue and what does that indicate?
A: Blue housing indicates a specific keyed connector type for safety. Color-coded housings prevent accidental mating of incompatible connectors. Blue AN-244 housings will only mate with blue keyed inserts and plugs, ensuring correct polarity and voltage routing.
Q: What current and voltage is the AN-244 SB350 housing rated for?
A: SB350 housings typically accept wire gauges up to 1/0 AWG or larger and are rated for 600 volts AC/DC maximum. Current capacity depends on wire gauge used and contact configuration but typically ranges from 300 to 400 amps continuous duty. Consult the equipment manual for exact amperage specifications.
Q: Is the AN-244 housing genderless or polarized?
A: SB350 connectors are genderless assemblies, meaning male and female contacts are interchangeable within the same keyed system. This eliminates the need for separate male and female connector sets and allows flexibility in assembly. Keying and color coding prevent reverse polarity rather than gender differences.
Q: What environmental conditions can the AN-244 withstand?
A: The AN-244 SB350 housing has IP64 environmental protection—dust-proof and splash-resistant. It is suitable for wet dock environments, outdoor yards, and cold storage. The polycarbonate housing resists UV, chemicals, and temperature extremes. Do not fully submerge as seals will eventually degrade.
Q: How do I know when the AN-244 housing needs replacement?
A: Replace the AN-244 housing if you observe cracks, significant discoloration, corroded silver-plated contacts inside, difficulty mating/unmating, intermittent connections, or signs of internal arcing. Also replace if seals appear deteriorated or shrunk. Do not attempt to clean corroded contacts extensively as this can damage the plating.
