Overview
The Festo SMT-8M-24V proximity switch is a compact, magneto-resistive sensor designed for T-slot installations in pneumatic cylinders and automation equipment. This proximity switch is designed for T-slot installation and offers a 3-wire PNP normally open output with 24 V DC operation. It features a 0.3 m cable with rotatable M8 plug, magneto-resistive sensing, and IP69K protection. The sensor provides consistent, non-contact position detection with minimal maintenance requirements.
Key Features
- Magneto-Resistive Technology: Measuring principle: magneto-resistive for reliable, wear-free operation
- PNP 3-Wire Output: Normally open contact for direct integration into industrial controls
- IP69K Protection Rating: IP69K protection ensures operation in high-pressure washdown and harsh environments
- LED Status Indicators: LED switching status indication, LED operating reserve indication
- M8 Rotatable Connector: Rotatable M8 plug for flexible mounting and cable routing
- Wide Cable Length Options: Cable length 0.1 … 30 m available for system integration
