product parameters

Product Name: Proximity Switch
Part No.: 803604501
Applicable Model: XCMG ZL50G, ZL50GL Wheel Loader
Type: Non-contact position detection switch
Installation Position: Installed at original detection point position
Function: Position/travel detection, limit or in-position signal output

Applicable Scenarios

Widely used in quarry, aggregate yard, and earthwork construction sites with heavy dust and obvious vibration. It is an electrical switch accessory for ensuring accurate machine control logic and reliable limit or in-position detection.

▪ Non-contact detection reduces mechanical wear
The proximity switch detects moving component position through its sensing face without direct contact, avoiding mechanical wear, contact burning, and seizure common in long-term contact-type switches, making it suitable for frequent actuation conditions.

▪ Factory sensing function inspection for stable signal output
Sensing distance, signal output, and wiring condition are inspected before shipment, reducing electrical faults such as intermittent signal or sensing failure after installation and lowering rework and downtime probability.

▪ Housing protection against dust and vibration
The housing structure provides certain protection against dust, mud splash, and machine vibration, suitable for long-term use in harsh environments such as mines, aggregate yards, and earthwork sites.

▪ Mounting matches original detection point for easy replacement
Installation position, sensing direction, and wiring interface are designed to the original detection point, requiring no bracket or harness layout modification during replacement and shortening on-site repair time.

▪ Fast response meets real-time control logic requirements
The proximity switch outputs signals quickly, promptly feeding back in-position or limit status of moving components, ensuring accurate control logic judgment and reducing action delay or malfunction.

FAQ 

Q：When does a proximity switch need replacement?
A: Replace when sensing function failure causes corresponding control function abnormality, signal is intermittent, housing is damaged, wiring is broken, or mounting loosens.

Q：Is control function abnormality always caused by the proximity switch?
A: Not necessarily. Check harness connectors for looseness, fuses for normality, and other control system components for faults first. Inspect the proximity switch sensing function after confirming peripheral circuits are normal.

Q：What to note during proximity switch installation?
A: Confirm the installation position and sensing distance meet original requirements and clean the sensing face before installation. Check wiring polarity and test corresponding control functions after installation.

Q：How to maintain the proximity switch daily?
A: Regularly clean the sensing face to prevent oil and dust accumulation from affecting sensing distance. Check mounting fixation for looseness and wiring for wear, and address abnormalities promptly.
