Overview
The Baumer CFDK 25G1125/KS35LN4 is an industrial-grade capacitive proximity sensor designed for non-contact object detection and level sensing. It features an 8mm nominal sensing distance, push-pull output circuit, and M8 flylead connector with 200mm cable length. Operating temperature range spans -25 to 75°C with IP65 ingress protection and red LED output indicator.
Key Features
- Flush-mounted design for clean panel integration
- No external sensitivity adjustment required
- Detects non-conductive media and enables fill level detection through containers
- Push-pull output circuit with 100mA output current and <3VDC voltage drop
- Short circuit and reverse polarity protection
- Low current consumption at 15mA maximum (no load)
