Frequently Asked Questions
Q: What is the BJ 1120-500006-00 limit switch used for?
A: The BJ 1120-500006-00 is a lifting limit switch that provides mechanical over-travel protection for Big Joe electric pallet jacks and stackers. It uses a snap-action roller plunger mechanism to automatically cut power when the mast reaches maximum height.
Q: Which Big Joe models are compatible with the BJ 1120-500006-00?
A: The BJ 1120-500006-00 is compatible with Big Joe models D40, EZ40, J0, JE, K22, LPT44, and WPT45 electric pallet jacks and stackers. Verify your equipment model and serial number before ordering.
Q: What are the electrical specifications of the BJ 1120-500006-00?
A: The BJ 1120-500006-00 operates at 24VDC nominal control voltage with a rated current of 2A at 24VDC. The single-pole, single-throw (SPST) contact configuration breaks the lift circuit when activated.
Q: What materials are used in the BJ 1120-500006-00 housing and actuator?
A: The BJ 1120-500006-00 features a thermoplastic housing for chemical resistance and electrical isolation, with a stainless steel actuator plunger. This combination resists corrosion and extends service life in warehouse and industrial environments.
Q: What happens if the limit switch fails or becomes stuck?
A: A failed limit switch creates a safety hazard by removing over-travel protection. The truck operator may be unable to stop the mast before it extends beyond maximum safe height. Replace the BJ 1120-500006-00 immediately if it fails to stop mast travel or remains stuck in the activated position.
Q: How do I know if the BJ 1120-500006-00 needs replacement?
A: Replace the BJ 1120-500006-00 if the mast continues to rise past the normal limit position, if the switch contacts stick open or closed, or if the roller plunger is cracked or worn. Test by slowly raising an empty truck to confirm the switch stops lift at the correct height.
