Applications
The 20.155MV/4 is suited for industrial automation panels, building management systems, and sensor interface boards where 4-circuit wire-to-board connectivity at 3.5 mm pitch is required. It is commonly used in PLC I/O modules, relay driver cards, and HVAC control boards that need polarized, secure connections to field wiring harnesses. The through-hole mounting style makes it a reliable choice in environments with mechanical vibration or thermal cycling where solder joint integrity is critical.

Frequently Asked Questions
How many circuits does the 20.155MV/4 header support and what is its contact pitch?
The 20.155MV/4 is a 4-way (4-circuit) box header with a 3.5 mm center-to-center pitch between contacts. This pitch is standard for compact wire-to-board connectors used in industrial and building automation, accommodating wire gauges typically from 24 AWG to 16 AWG and rated for currents up to 8 A per contact depending on wire size.
How does the shrouded polarized design of 20.155MV/4 prevent wiring errors during field installation?
The 20.155MV/4 features a shrouded box housing that encloses all 4 contacts and includes a polarization key, physically preventing the mating plug from being inserted in the wrong orientation. This reduces the risk of reverse-polarity wiring errors in field installations, protecting connected sensors, actuators, and control circuits from damage during commissioning or maintenance.
Which industrial control applications commonly use the 20.155MV/4 connector on their PCBs?
The 20.155MV/4 is widely used in PLC analog I/O modules, relay output cards, HVAC sensor interfaces, and motor drive auxiliary terminals where 4-wire field connections at 3.5 mm pitch are needed. Its through-hole mounting provides strong PCB retention suitable for DIN-rail-mounted control panels that may experience vibration levels above 2 g in industrial environments.
What mating plug types are compatible with the 20.155MV/4 header for field wiring?
The 20.155MV/4 mates with standard 3.5 mm pitch pluggable terminal block connectors or crimp-style plug housings that accept 4 contacts. These mating plugs typically use screw-clamp or spring-clamp wire termination for 28 AWG to 16 AWG wire, allowing field technicians to connect and disconnect wiring without desoldering the header from the PCB.
