Overview
The SMC D-Y7P auto switch cable is a solid-state auto switch sensor designed for direct mounting to pneumatic cylinders and actuators. Unlike traditional reed switches, the D-Y7P offers solid-state reliability with an integrated indicator light and built-in surge protection. This sensor is compatible with SMC actuators and is widely used in manufacturing automation, packaging lines, assembly systems, and industrial control applications requiring position feedback.
Key Features
- Solid-State Design: No moving parts, enhanced durability and lifespan compared to reed switch alternatives.
- 3-Wire PNP Configuration: Direct integration with modern PLC and industrial controller inputs without isolation modules.
- Multi-Voltage Support: Operates across DC5V, DC12V, and DC24V (with input range DC4.5–28V for flexibility).
- 0.5m Oilproof Cable: Heavy-duty vinyl-insulated lead wire (ø3.4mm) resists oil and mechanical damage in harsh environments.
- Integrated Indicator Light: Visual feedback for switch status without external diagnostics.
- IP67 Rated: Watertight construction meets IEC 60529 standards for wet or dusty operating conditions.
