Neutrik* PowerCON connectors are sealed couplers with locking device that guarantee a safe power connection in rugged conditions. Among others they are used for on stage performances and applications in harsh outdoor environment. 250V connectors, appliance inlets and outlets exist for 16A, 20A and 32A.

Image no. 14 shows the original XLR connector designed by Cannon Electric Co. in the 1950s.
Image nos 15 and 16 show a Neutrik XLR connector based on the Cannon original.

* Neutrik A.G. in Schaan, Liechtenstein, designer and manufacturer of appliance couplers for audio, video, lighting, power and data applications.


Neutrik 16A NAC3FX-W and NAC3MX-W_parts

1, 2 Neutrik PowerCON TRUE1 TOP* cable connectors rated at single phase 16A - 250V (USA: 20A - 120V).
(a) NAC3MX-W-TOP locking male connector;  (b)
NAC3FX-W-TOP locking female connector;  (c-d) NAC3PX TOP appliance inlet (c) and outlet (d) combination. Rubber, flexible covers for in- and outlet can be added. Separate inlet and outlet units exist also.
Female connector fits in inlet 'c'; male connector in outlet 'd'.

Neutrik PowerCON TRUE1 TOP 16A connectors and appliance in-/outlets fully comply with IEC 60320 standard specifications, which among others means that connection and disconnection under load or live is allowed.

* TOP stands for True Outdoor Protection (IP65).

3 Front view of NAC3FX-W-TOP. Line, neutral and earth contacts are located in confined spaces.
Female connectors and appliance outlets (image 1d) have four cams (green arrows). The top left cam is wider than the other three. Male connectors and appliance inlets have corresponding notches. The wide cam serves to position a male connector correctly, see image 4; any other position is impossible.
4 (a)  Procedure to connect and lock male (right) and female (left) connectors.
(b)  As explained in the caption to image 3, there is only one position in which the male connector fit.
(c)  Male and female connectors are nearly fully plugged into each other, but electrical contact has not yet been made.
(d)  Press male connector further inwards and rotate 30 degrees clockwise to lock and make electrical contact.
To unlock, shift the metal clip of the female connector backwards and rotate male connector counterclockwise.

NAC3FCA lockable cable connector, assembled (5) and the four separate connector components (6). Rating: single phase 20A - 250V. Image no. 7 show a front view of the connector. Rating: single phase 20A - 250V.

20 and 32 Amp devices are designed for professional use of audio, video and power appliances, and should not be connected or disconnected under load or live.
NAC3MPA-1 chassis inlet. To plug in the connector, the wider cam (see image no. 7; blue arrow) has to be positioned in the top notch.
9 To make contact, the connector has to be fully plugged into the inlet and then rotated 30 degrees clockwise. The tip of the yellow clip springs automatically in large notch of the inlet and locks the connector fully. To remove the connector, the yellow clip has to be moved backwards manually whereafter the connector can be rotated counterclockwise and pulled out.

XLR connectors

Cannon XLR type 3pin-connector

In 1950 the Cannon Electric company in Los Angeles, California introduced the Cannon X series connectors for audio, video and stage lighting applications. In 1955 a latch was added to lock connectors. The series was renamed XL.
The original model had 3 poles, but 4 - 7 pin models have been added to the range: XLR3, XLR4 ..... XLR7.
See Wikipedia for more information about XLR connectors.
