Overview
The Hyde Park SM502A-473 is a compact ultrasonic proximity sensor from the Superprox family (Telemecanique Sensors / Schneider Electric). It operates at 12-24V DC with a 60mA maximum current consumption and delivers discrete on/off switching output. With a 2-meter sensing range and field-adjustable detection window, this sensor is designed for reliable contactless detection of objects regardless of color, surface texture, or material composition.
Key Features
- Discrete Output: Direct on/off switching suitable for PLC and logic controller integration
- Wide Voltage Range: 12-24V DC operation offers flexibility in system integration
- Field-Adjustable Sensing Window: Allows fine-tuning of detection distance and hysteresis on-site
- Potted Cable Design: Sealed construction protects against moisture, dust, and contamination
- IP67 Rating: Fully sealed enclosure for harsh industrial environments
- Contactless Detection: Ultrasonic technology works on any material—transparent or opaque, hard or soft
