Sick EN2EX-1 Switch Amplifier

The SICK EN2EX-1 Switch Amplifier (part number 6010459) is a compact intrinsically safe NAMUR amplifier designed to interface safety sensors with a single, changeover relay output in hazardous environments. It supports up to two sensor inputs or one through-beam input and provides one SPDT relay output. The unit offers intrinsic safety with II (1) G/D [EEx ia] IIC ratings and ensures reliable isolation between input, output, and supply, meeting ATEX and related safety standards. Power is supplied from 115 VAC, and the enclosure is IP20, with 35 mm DIN-rail mounting per DIN EN 60715. Indicator LEDs include a red cable-monitoring LED, a yellow switch-status LED, and a green supply LED. The EN2Ex family emphasizes configurable action; outputs can be inverted via the device's adjustment options, and the model is designed for NAMUR-compatible sensors or mechanical contacts with appropriate resistance networks. SICK lists EN2EX-1 as a safety-switching amplifier in its product families; note that some distributors report the item as discontinued by the manufacturer.
