Overview
The Turck 8MB12Z-5-CS19 is a passive M12 Eurofast low-profile junction box designed for field-level sensor and actuator signal consolidation in industrial automation and machine control. This 8-port multibox provides a compact, rugged wiring solution that reduces homerun cable complexity by combining multiple I/O signals over a single M23 multifast connector. The unit is housed in durable plastic with nickel-plated brass receptacles and is rated IP67/IP69K for indoor and outdoor machine environments.
Key Features
- 8 × M12 Eurofast 5-pin female connectors (low-profile design)
- 1 × M23 multifast 19-pin male homerun connector (top-exit)
- 2 signals per port; up to 16 I/O signals consolidated into single homerun
- 10–30 VDC operating range; 2A current rating per port
- IP67/IP69K environmental protection for wet, dusty, and wash-down areas
- Surface-mount plastic housing with nickel-plated brass contacts
- Operating temperature range: −40 to +85°C
- No active electronics; completely passive design ensures reliable operation
