Frequently Asked Questions
Q: What is the RA 1105029 electromagnetic contactor and what does it control?
A: The RA 1105029 is a genuine OEM 24VDC electromagnetic contactor for Raymond electric lift trucks. It switches high-current DC power circuits on and off to control propulsion motors, lift motors, and hydraulic pump operation based on operator commands and control system signals.
Q: What are the electrical specifications of the RA 1105029 contactor?
A: The RA 1105029 operates at 24VDC nominal coil voltage with four terminal configuration: two 0.250-inch dual terminals on one side for high-current power switching. It features silver alloy contacts rated for continuous DC duty cycles and a sealed enclosure protecting against dust and moisture in industrial environments.
Q: Which Raymond electric lift truck models use the RA 1105029 contactor?
A: The RA 1105029 is compatible with specific Raymond electric pallet jack and counterbalanced lift truck models. Cross-reference your equipment model and electrical system to confirm compatibility. Related cross-references include 1105029, RA1105029, 1-105-029, and SK-05201230TB.
Q: How long does the RA 1105029 contactor typically remain reliable?
A: OEM contactors typically operate reliably for years of continuous duty in electric material handling equipment. Lifespan depends on electrical load cycling frequency, contact arcing, control system reliability, and maintenance practices. Regular inspection of contact condition extends service life.
Q: What failure symptoms indicate the RA 1105029 contactor needs replacement?
A: Signs of contactor failure include inability to energize motors, intermittent motor engagement, clicking or chattering sounds, burning odor near electrical components, corroded or pitted contacts, or complete loss of propulsion or lift power. Electrical testing confirms contactor failure before replacement.
Q: Are there equivalent part numbers or cross-references for the RA 1105029?
A: Yes, the RA 1105029 contactor can be cross-referenced to part numbers 1105029, RA1105029, 1-105-029, and SK-05201230TB. These are equivalent designations for the same OEM component. Always verify coil voltage, terminal configuration, and equipment compatibility when ordering replacements.
