PT8420, Cable Actuated Sensor
- Absolute Linear Position to 60 inches (1524 mm)
- Aluminum or Stainless Steel Enclosure Options
- VLS Option to Prevent Free-Release Damage
- IP68 / NEMA 6 • Hazardous Area Certification
The PT8420 cable-actuated sensor stands out in the industrial sensing domain, offering unparalleled reliability and accuracy for monitoring hydraulic cylinders and other critical position data acquisition needs in harsh conditions. With its 4-20 mA (2-wire) or optional 0-20 mA (3-wire) output signals, this sensor delivers feedback that is directly proportional to the linear displacement of its durable stainless-steel extension cable. Installation is straightforward, requiring the body to be mounted on a fixed surface and the cable attached to the moving part.
Designed to thrive in challenging environments, the PT8420 features a choice of powder-painted aluminum or stainless steel enclosures and offers hazardous area certifications, ensuring operational safety and durability. Full stroke range options from 0-2 to 0-60 inches and the inclusion of a Velocity Limiting System (VLS) option to prevent free-release damage further enhance its applicability across various industrial scenarios.
Key specifications include a repeatability of ±0.05% full stroke, essentially infinite resolution, and a maximum input current of 20 mA. The sensor supports a broad operating temperature range of -40° to 200°F, with vibration resistance up to 10 g's to 2000 Hz, and comes with NEMA 4/4X/6, IP 67/68 enclosure ratings for comprehensive protection against the elements.
