1157852

Overview

The Phoenix Contact 1157852 is an Ex i-NAMUR signal conditioner designed for use in explosive gas environments. It operates proximity sensors and switches within the hazardous area, transmitting signals to safe zones via two passive transistor outputs. This DIN rail-mounted device provides isolation, conversion, filtering, and amplification for electrical circuits entering dangerous zones.

Feature Summary

• Designed for operation in explosive gas areas (Ex zones)
• Transmits signals from proximity sensors and switches to safe areas
• Features two passive transistor outputs for signal transmission

Applications

• Operating proximity initiators in Ex zones
• Connecting switches in hazardous areas
• Signal conditioning for NAMUR sensors in explosive atmospheres

Procurement Notes

Verify the specific part number 1157852 against official Phoenix Contact documentation to confirm it matches the MINI MCR-EX-NAM-2T designation. Ensure the application environment requires Ex i-NAMUR certification. Check for any ordering suffixes that may alter technical specifications or certifications before procurement.

Selection Notes

Select this component when isolation and signal conversion are required for NAMUR sensors in hazardous locations. The dual passive transistor output configuration supports specific interface requirements for connecting to control systems while maintaining safety barriers between the explosive zone and safe areas.

Part Context

This unit belongs to the MINI MCR series of isolation amplifiers by Phoenix Contact. The series focuses on compact DIN rail mounting solutions for industrial automation. The MINI MCR-EX variant specifically addresses safety requirements for equipment operating in potentially explosive atmospheres.
