Ex Junction Box

Product catalog summary

Overview: The document provides technical specifications for an explosion-proof junction box designed for incremental encoders, manufactured by Scancon. It includes mechanical, electrical, and environmental specifications, as well as connection details and ordering information.

Mechanical Specifications: The junction box is made of aluminum (AlSi12Cu1Fe0.3) with stainless steel fasteners. It weighs approximately 1300 grams without cable glands and blinds.

Common Specifications: The update rate is 1.04 million updates per second with a transmission delay of ≤ 3µsec. The recommended optical fiber is 62.5/125 µm multimode with a transmission distance of up to 2000 meters.

Electrical Specifications - Transmitter: The supply voltage ranges from 4.75V to 30V with varying current consumption based on voltage. It supports differential inputs with a maximum encoder frequency of 100 kHz.

Environmental Specifications: The operating temperature ranges from -20°C to +70°C, with a storage temperature of -40°C to +85°C. It has an IP67 enclosure rating and complies with EMC standards EN 61000-6-2 and EN 61000-6-3.

Certifications: The junction box is certified with CE 0359, II2 G Ex d IIC T6, and II2D Ex tD A21 IPx T85°, applicable only to the junction box.

Electrical Specifications - Receiver: Similar supply voltage range as the transmitter with different current consumption. It provides differential outputs with specific voltage requirements.

Connection Details: Detailed terminal connections for both transmitter and receiver are provided, including channel inputs and outputs, supply connections, and shield connections.

Ordering Information: The document includes an example ordering code and options for cable glands, specifying dimensions and materials.
