Product catalog summary

Conveyor Sensor Systems Overview
Eaton's Conveyor Sensor Systems focus on Zero Pressure Accumulation (ZPA) solutions to prevent product damage and mishandling on outdated conveyors. These systems utilize non-contact sensors and integrated control solutions.

E68 Series Integral Sensor Valve
The E68 Series offers a complete ZPA sensing and control solution, including sensors, air valves, connectors, power supplies, and accessories. It supports multiple algorithms for customized functionality and features low installation costs with optimized wiring.

200 Series Zero Pressure Accumulation
This series provides a non-contact, photoelectric sensor system with built-in accumulation control, compatible with solenoid-operated air valves and featuring short circuit protection. It is designed for easy installation with pre-measured wiring.

Sensor Power Supplies
Two types of power supplies are available: NEMA 4 Universal Voltage and NEMA 1 120 Vac, both providing 100W output at 27 Vdc. They include integrated AC junction boxes for easy mounting and wiring, and built-in DC power health contacts for monitoring.

Technical Data and Specifications
Detailed technical specifications include electrical ratings, enclosure ratings, and material compositions. The systems are warranted for up to 60 million operations over three years and are cULus approved.

Standards and Certifications
All products are certified by cULus but are not intended for functional safety applications as per IEC 60947-5-3 standards.

Important Note
The sensors are not safety devices and should not be used as such. They are designed solely for data detection and control purposes.

Product Specifications
The E68 Series includes various sensor types with different sensing ranges and field of view specifications. Sensors operate in 'Air to drive' or 'Air to brake' modes, specified by catalog numbers.

Accessories
Accessories include cables for sensor output, power supply, and release functions, as well as zone extension cables, power jumpers, and zone jumpers for configuring conveyor systems.

Technical Data
Specifications cover input voltage, power dissipation, response time, and environmental conditions. Sensors are designed to operate within specific temperature ranges and are constructed from durable materials.

Wiring Diagrams
Wiring diagrams for typical daisy-chain and multi-drop buss configurations illustrate connections between sensors, power supplies, and control interfaces.

Dimensions
Approximate dimensions for the E68 Series Integral Sensor Valve and its mounting bracket are provided, with diagrams showing the layout for different models.

Product Features

Non-contact ZPA control without a PLC.
Multiple algorithms for specific functionality.
Low installation costs with pre-measured wiring.
Compatible with solenoid-operated air valves.

Installation and Reliability
The system reduces installation costs by eliminating custom connectors and measuring. The main buss cable is pre-installed with connectors matching conveyor zone lengths.

Safety Warning
The sensor is not a safety device and should not be used as such. It lacks self-checking redundant circuitry, and failure could result in hazardous conditions.

Specifications and Components

Power Supply Cables: Various lengths and types are available to connect power supplies to conveyor zones.
Buss Link Cables: Used to connect sections of buss harness, with options for power isolation.
Sensor Specifications: Include input voltage, power dissipation, and output types. Sensors are protected against short circuits and have a response time of 8 ms.

Optical Performance
Optical specifications guarantee minimum performance under clean conditions. Sensors should be used where excess gain is higher than 1.5 to overcome contamination on the lens.

Installation: Instructions for mounting power supplies and connecting sensors, emphasizing correct connectors and signal direction.

Sensor Power Supply

NEMA 4 Universal Voltage: Designed for use with 200 Series and E68 Series systems, providing 100W output at 27 Vdc.
Standards and Certifications: cULus Class 2 certified, with a warning that the sensor is not a safety device.

Technical Data

Output Protection: Short circuit, overload, and overvoltage protection with auto-reset capabilities.
Environmental Ratings: Operating temperature range from -13°F to 131°F, with NEMA 4X enclosure rating for durability.

Features

Integrated AC junction box for easy mounting and wiring.
Built-in DC power health contact for monitoring power supply status.
Tamper-proof encapsulated construction to minimize damage risks.
Built-in slug-release input for AC or DC input conversion.
Dual output connection terminals for convenient power supply location.

Technical Specifications

Operating Voltage: 105–132 Vac
Output: 27 Vdc, 100W with protection features
Slug Input: 15–132 Vac/dc
Temperature Range: –13° to 131°F (–25° to 55°C)
Enclosure Material: Die-cast aluminum
Enclosure Rating: NEMA 1

Product Variants
