Frequently Asked Questions
Q: What is the YL 512456803 contact used for?
A: The YL 512456803 is an electrical contact assembly for Yale lift truck control circuits. It closes or opens electrical paths to activate motor, solenoid, or auxiliary functions based on operator input or system signals.
Q: What Yale lift truck platforms use this contact?
A: This contact fits multiple Yale electric pallet jack and walkie stacker models. It is used in proportional and non-proportional control systems across various model years. Verify your exact platform and serial range for correct fitment.
Q: What are the electrical specifications?
A: The YL 512456803 is rated for standard industrial DC circuits used in Yale equipment, typically 12V to 48V depending on truck model. Amperage capacity matches the load it controls, ranging from 5 to 40 amps for typical functions.
Q: What failure signs indicate the contact needs replacement?
A: Failed contacts cause intermittent loss of function, stuck activation, or no response when triggered. Electrical testing may reveal an open circuit, high resistance, or visible contact pitting and burn marks.
Q: How long do these contacts last before wearing out?
A: Typical lifespan is 4-7 years depending on switching frequency and current load. High-frequency switching or operation in dirty environments can accelerate wear. Contact erosion is normal and indicates replacement is needed.
