CUAZOAL61SDOA00 male electrostatic balancing plug
CUAZOAL61SDOA00
In brief. The CUAZOAL61SDOA00 is the grounding plug that terminates the refueller's grounding cable and connects to the aircraft's receptacle. CuZn39Pb2 brass plug made to NF L 94-111A, polychloroprene handle, 70 g, cable soldered into the tail. NATO Stock Number (NSN) 5935-14-283-6116, manufacturer reference 701. We source it or reproduce it; quote within 48 working hours.
It is the only male part in our aeronautical electrostatic balancing range. This page explains what it connects, how to wire it and which NSN to quote, as the number previously shown on our site was incomplete.
What does an electrostatic balancing plug do?
It brings the aircraft and the refuelling equipment to the same potential before the fuel is turned on. US patent 4525014 (1985) describes the risk: without a grounding connection between the two, a static charge builds up and can produce an arc that ignites the fuel. The plug is the mobile part of that connection, handled at every operation.
The French standard NF L94-111 already named this part in 1955: "Fiche d'équilibrage électro-statique du dispositif de remplissage en combustible" (electrostatic balancing plug for the fuel filling device). The current French term is "mise à la terre"; in English, grounding plug or bonding.
What are the characteristics of the CUAZOAL61SDOA00?
| Characteristic | Value |
|---|---|
| Type | Male assembly: plug and handle |
| Manufacturer code | 701 |
| Plug | CuZn39Pb2 brass, made to NF L 94-111A |
| Handle | Polychloroprene |
| Weight | 70 g |
| Connection | Conductor soldered into the tail of the plug |
| NATO Stock Number | 5935-14-283-6116 |
CuZn39Pb2 is a leaded brass (European designation CW612N, 1.6 to 2.5% lead according to EN 12164) valued for its machinability. Polychloroprene is the elastomer known by the trade name neoprene. The original manufacturer is CKB, later taken over by Deutsch and then by TE Connectivity; we source the part independently and are not an official distributor.
Why is the referenced standard an issue?
The plug is "made to standard NF L 94-111A". Yet AFNOR states that the April 1975 edition of NF L94-111 has been withdrawn. Our view: that is precisely what makes the part hard to find. A plug defined by a withdrawn standard can no longer be ordered from a standard catalogue. We search for it using its reference, its NSN and its dimensions, then design a compatible alternative if needed.
Which receptacles does it connect to?
The current datasheet declares it compatible with the 700S, 700E, 710, 720 and 740 receptacles. Three of them are in our range:
- 700S: CUANOAL61SOV000 electrostatic balancing socket;
- 700E: CUABOAL1SSOV000 electrostatic balancing socket;
- 710: CUABOAL61SOR000 waterproof electrostatic balancing socket.
The 720 and 740 receptacles are not listed online: state their reference in your request.
How do you identify the CUAZOAL61SDOA00?
Look for the brass plug extended by a polychloroprene handle, then check the NSN. Our site used to show "59-14-283-6116", an incomplete format: an NSN starts with a four-digit class. The correct number is 5935-14-283-6116, codified by France; the public ISO Group database links it to manufacturer reference 701.
| Reference | Manufacturer code | Type | Flange | NATO Stock Number |
|---|---|---|---|---|
| CUABOAL61SOR000 | 710 | Waterproof aircraft-side receptacle, lock nut on bulkhead | Round | 5935-14-241-5600 |
| CUABOAL1SSOV000 | 700E / 20653 | Female receptacle, 3 bolts | Triangular | 5935-14-213-6073 |
| CUANOAL61SOV000 | 700S | Female receptacle, 3 bolts | Triangular | 5935-14-401-6611 |
| CUAZOAL61SDOA00 | 701 | Male plug with handle | Not applicable | 5935-14-283-6116 |
Frequently asked questions
How is the CUAZOAL61SDOA00 connected to the cable?
The conductor is soldered into the tail of the plug. This is not a screw terminal, so plan for a soldering station when replacing it. The permissible cable cross-section is not published: state the one used on your reel in your quote request and we will check compatibility before pricing.
Does the CUAZOAL61SDOA00 replace a US MS3493 plug?
There is nothing to confirm that. The MS3493 falls under the US specification MIL-DTL-83413, whereas the CUAZOAL61SDOA00 is made to the French standard NF L 94-111A. Before any substitution, compare the interface dimensions with your receptacle; we can carry out this comparison from a drawing.
Which NSN should be quoted in an order?
Quote the reference CUAZOAL61SDOA00 and the number 5935-14-283-6116, which replaces the "59-14-283-6116" shown previously. This number appears in the public ISO Group database with manufacturer reference 701. If in doubt, the reference alone is enough: we will match it.
