Contactor Solenoid
Frequently Asked Questions
Q: What is the YL 0957643BA contactor solenoid?
A: The YL 0957643BA is a solenoid coil for an electrical contactor used in Yale electric lift truck control systems. It energizes the contactor to route power to drive motors, pump motors, or hydraulic solenoids.
Q: What equipment uses the YL 0957643BA contactor solenoid?
A: The YL 0957643BA is specified for Yale electric pallet jacks, walkie stackers, and straddle carriers from multiple production years. Cross-reference your equipment model and serial number with Yale documentation to confirm fitment.
Q: What voltage and amperage does the YL 0957643BA solenoid handle?
A: The YL 0957643BA is typically a 24V or 36V DC coil rated for 50 to 100 amperes depending on the contactor size. Verify your truck system voltage and the contactor coil rating before ordering.
Q: How do I know if the YL 0957643BA solenoid is failing?
A: Failed symptoms include intermittent drive or lift loss, loud buzzing with no contactor engagement, or complete loss of function. Test coil resistance and continuity with a multimeter. Excessive heat on the coil also indicates failure.
Q: What is the lifespan of the YL 0957643BA?
A: This contactor solenoid typically lasts 5 to 7 years in normal operation. Lifespan decreases with high cycling frequency, moisture, and high ambient temperature. Replace if coil resistance rises or if contactor becomes slow to engage.
Q: Is there a cross-reference part for the YL 0957643BA?
A: YL 0957643BA is the Yale OEM solenoid. Cross-references may exist from Toyota or Crown if your equipment is a common platform. Confirm voltage, coil resistance, and physical dimensions match before using a substitute.
