CBB8-18GS75-E2-V1 Pepperl+Fuchs Capacitive Proximity Switch 10-30V
DC
Product Overview
This sensor features an M18 threaded brass nickel-plated housing,
an 8mm detection distance, and a normally open PNP output. It is
designed for high-precision, non-contact detection in IIoT
(Industrial Internet of Things) environments. Supporting the
IO-Link V1.1 communication protocol, it retains traditional switch
outputs while enabling real-time uploading of process data,
equipment status, and diagnostic information. It is a core sensing
element for predictive maintenance and digital factories, widely
used in automotive parts, food and beverage, pharmaceutical
machinery, and intelligent logistics systems.

V1 Enhanced Features
1. IO-Link Intelligent Communication Capability
The CBB8-18GS75-E2-V1 achieves the following digital functions
through the V1 firmware:
- **Process Data Visualization**: Real-time upload of detection
distance (0.1mm resolution), echo amplitude, and temperature value
- **Remote Parameter Configuration**: Online adjustment of
detection distance, hysteresis, and response time via PLC/HMI,
without physical contact
- **Equipment Identification and Traceability**: Automatic upload
of manufacturer, model, serial number, and firmware version to the
MES system
- **Predictive Maintenance**: Monitoring sensor health status
(runtime, switching count, temperature alarm), providing early
warning of end-of-life
2. Intelligent Diagnosis and Event Logging
- **Diagnostic Data**: Low power supply voltage, overload, short
circuit, overheating, and sensor surface contamination
- **Event Timestamp:** Records the last 100 state change events
with an accuracy of 1ms.
**Quality Indicators:** Provides signal quality percentage,
quantifying detection reliability.
**Teach-Lock:** Prevents unauthorized parameter modification,
meeting GMP verification requirements.
3. Multi-Mode Operation
**SIO Mode:** Compatible with traditional PNP switch signals,
operates without an IO-Link master station.
**IO-Link Mode:** Full-featured digital communication, supports
periodic data exchange (1ms cycle).
**Combined Mode:** Switch output + IO-Link diagnostics in parallel,
balancing real-time performance and intelligence.
Typical Application Scenarios
Intelligent Assembly Line Workpiece Inspection
**Application:** New energy vehicle battery module assembly,
detecting whether the insulation film is in place.
**Solution:** The CBB8-18GS75-E2-V1 is installed on the robot
fixture, and the IO-Link uploads the film thickness data to the
PLC. When the detected value deviates from the standard range of
±0.2mm, the system automatically stops and prompts for fixture
replacement. Compared to traditional switch-type solutions, this
increases the defect detection rate from 95% to 99.8%, reducing
rework costs by over 500,000 RMB annually.
Intelligent Filling Line Level Monitoring
**Application**: Infant formula bottling production line,
non-contact detection of liquid levels inside glass jars.
**Solution**: Sensors penetrate 8mm glass walls, and IO-Link
outputs real-time liquid level values. AI algorithms analyze liquid
level fluctuation trends to predict the wear cycle of filling
valves. When three consecutive instances of exceeding the filling
tolerance are detected, a maintenance work order is automatically
triggered, improving overall equipment efficiency (OEE) by 12%.
