Frequently Asked Questions
Q: What is contact A-28846-5 used for in electric lift trucks?
A: Contact A-28846-5 is an electrical switching component in electric pallet jack control circuits. It manages power flow to lift and lower solenoids, directional relays, and motor circuits. This contact is part of the main contactor or relay assembly in the truck controls.
Q: Which electric pallet jack models use this contact?
A: Contact A-28846-5 is compatible with electric pallet jacks from Crown, Toyota, Raymond, Jungheinrich, Linde, and BT. Compatibility depends on control circuit configuration and voltage rating. Cross-reference your truck model and control panel specifications before ordering.
Q: What are the electrical specifications for this contact?
A: This contact is rated for typical electric pallet jack control voltages of 24VDC or 48VDC. Contact current rating and switching frequency depend on application. Verify voltage and amperage requirements from your truck control circuit before installation.
Q: What indicates that contact A-28846-5 needs replacement?
A: Replace this contact if the truck exhibits intermittent lift or lower function, failure to respond to control signals, or visible arc damage on contact surfaces. Burnt, pitted, or corroded contacts cause circuit failures. A faulty contact prevents proper truck operation.
Q: What is the typical service life of this contact?
A: Service life depends on switching frequency and electrical load. Contacts in high-use trucks typically last 2 to 4 years. Contacts subjected to voltage spikes, moisture, or corrosive environments may fail sooner. Regular inspection of the control panel improves reliability.
Q: Can contact A-28846-5 be used in different voltage systems?
A: No. This contact is designed for a specific voltage rating. Using a 24VDC contact in a 48VDC system or vice versa causes arcing, contact erosion, and circuit failure. Always verify the correct voltage rating for your truck before ordering.
