PROXIMITY SWITCH ASSEMBLY
Frequently Asked Questions
Q: What does the 370305 proximity switch assembly do on an electric lift truck?
A: The 370305 proximity switch assembly detects the position of the mast, fork carriages, or other moving components and sends a signal to the controller. It is typically mounted near a ferrous metal target and switches on or off when the target moves within its sensing range, controlling valve actuation, limit functions, or safety interlocks.
Q: What voltage and electrical specifications does the 370305 require?
A: The 370305 operates on standard electric lift truck voltage, typically 24V DC or 48V DC depending on your truck model. Verify your equipments control voltage and connector type before ordering. Incorrect voltage can damage the sensor or controller.
Q: Which electric lift truck models use the 370305 proximity switch assembly?
A: The 370305 is compatible with electric forklifts and lift trucks from major OEM manufacturers including Crown, Toyota, Raymond, Jungheinrich, Linde, and Yale. Confirm compatibility by referencing your truck model and serial number against the original equipment wiring diagram or parts list.
Q: What is the sensing range of the 370305 proximity switch?
A: Proximity switches typically detect ferrous metal targets from 5 to 15 millimeters away, depending on target size and material composition. Ensure the mounting bracket positions the 370305 at the correct distance from its target for reliable operation. Adjust mounting if the switch fails to trigger or triggers prematurely.
Q: What environmental factors affect the 370305 lifespan?
A: The 370305 is rated for standard material handling environments including temperature range, humidity, and light dust exposure. In wet storage, cold storage below zero Fahrenheit, or high-humidity outdoor use, lifespan is reduced. Inspect the sensor quarterly for corrosion, water ingress, or connector degradation; replace if damaged.
Q: How do I know if the 370305 proximity switch assembly is failing?
A: Failure symptoms include the mast not raising or lowering correctly, intermittent control loss, or the truck responding unpredictably to control inputs. Test the sensor output with a multimeter or controller diagnostic tool. If the output does not switch when the target moves, replace the assembly.
