Electrical Specifications
The junction box operates with a supply voltage range of 4.75V to 30V. Typical current consumption varies with supply voltage: 250 mA at 5V, 110 mA at 15V, and 70 mA at 30V, excluding the encoder. It supports differential encoder inputs with a maximum frequency of 100 kHz and input voltage equal to the supply voltage.

Common Specifications with Receiver
The update rate is 1.04 million updates per second, with a transmission delay of ≤ 3 µsec. An additional 1 µsec is added per 200 meters of fiber optic cable. The standard ST optical fiber connectors have an insertion loss of ≤ 0.7 dB, with 0.4 dB recommended. The recommended optical fiber is 62.5/125 µm, multimode, with an optical wavelength of 850 nm. Transmission distance can reach up to 2,000 meters.

Mechanical Specifications
The box is made of UL94-V0 self-extinguishing ABS with stainless steel front and cover plates. It weighs approximately 150 grams and measures 101 x 119 x 22.5 mm. It is designed for DIN rail mounting according to EN-50022 for 35mm rails.

Environmental Specifications
The operating temperature range is -20° to +70° C, and the storage temperature range is -40° to +85° C. It can withstand 98% relative humidity without condensation, 100 G shock for 11 ms, and vibration of 10 G from 10-2000 Hz. The enclosure rating is IP 40, and it complies with EMC standards EN 61000-6-2:2005 and EN 61000-6-3:2007.

Features
The junction box transmitter supports fiber optic transmission up to 2,000 meters without signal degradation from electrical disturbances. It offers high encoder frequency, low transmission delay, and added safety with two redundant fibers. It is compatible with all Scancon fiber optic receivers for incremental encoders and supports DIN rail mounting.
