Overview
The Phoenix Contact MSTB 2,5/16-ST (Part No. 1754724) is a 16-position pluggable printed-circuit board connector from the CLASSIC COMBICON system. Designed for demanding industrial and commercial PCB wiring, it features a screw connection with tension sleeve that ensures a secure, low-resistance connection. Rated at 12A nominal current and 320V, this green polyamide connector is suitable for a wide range of control panel and automation applications.
Features
- Well-known CLASSIC COMBICON connection principle — allows worldwide use and interoperability
- Low temperature rise thanks to maximum contact force for reliable, long-term performance
- Allows connection of two conductors per position (solid or flexible)
- Screw connection with tension sleeve (slotted drive, M3 thread, 0.5–0.6 Nm torque)
- Accepts conductors from 0.2–2.5 mm² (AWG 24–12) solid or flexible
- Tin-plated contacts for corrosion resistance
- 5 mm pitch, 1-level design, IP20 protection
- Pluggable female connector — easy field replacement without rewiring the PCB header
- Compact footprint: 18.2 L × 15 H × 80 W mm
