Plastic angled connectors with snap-in locks are difficult to design because they are sensitive to mishandling. For the 720 Miniature Series, Binder has developed a safe, robust, field-mountable angled version for applications with restricted installation conditions. The miniature NCC 770 series is now also available with an angled solution that allows the direction of the cable exit to be changed.
Binder, a leading supplier of industrial circular connectors, has complemented its 720 and 770 product series with a field-installable angled variation. Such compact angled connectors are used in device, architecture and plant engineering. Especially when you need to make a secure electrical connection in confined spaces, the 720/770 series angled versions with snap-in or bayonet locks offer reliable, space-saving connectors To do. Save straight version alternatives.
Background: Operational Safety as a Design Priority
For 720 snap-in series connectors, the electrical connection is mechanically secured by snap hooks that engage in appropriate slots, locking the interface. However, this type of lock can be mishandled. If the connector is pulled at an angle to the axis rather than axially, the plastic snap hook can break depending on the amount and direction of pulling force. To prevent failure in this application, Binder’s product developers inserted a threaded ring between the contact body and the angled housing. Therefore, the snap hooks are protected from damage even when forces are applied obliquely to the connector axis, allowing the connector to withstand loads far exceeding standard requirements.
An additional screw ring can satisfy two more design requirements.
- This concept also allows Binder to offer the 770 series as an angular variation using many identical parts.
- The contact body can be rotated in 90° increments, and the cable pull-out direction can be selected.
In general, if the housing angle is 90°, you have a problem with the cable routing. As you can see from other product series, it is often difficult to bend the cable 90 degrees. A 100° angle was therefore chosen for the new housing, greatly simplifying cable assembly.

The new angled version of the 720 snap-in series is used for lighting technology installations, greenhouse heating systems, e-bikes, etc. The series is specified in rated voltages from 60 V to 250 V and currents from 2 A to 7 A. For 3-12 pin interfaces, cable termination is done by soldering. It has an ingress protection rating of IP67 (when mated) and can withstand over 500 mating cycles.
The 770 series NCC (Not Connected Closed) angle connectors with bayonet lock are used, for example, in compact handheld control panels, home care medical equipment, laboratory weighing equipment, etc. that require particularly space-saving installations . For example, right next to a wall. The 8-pin interface is also equipped with solder terminals. The rated voltage and current are 175 V and 2 A respectively. In addition to IP67 when mated, the female panel mount connector also achieves his IP67 protection when unmated due to his NCC technology on the binder. Connectors withstand over 5,000 mating cycles.
Both the 720 and 770 series connectors are also available in the colors red, green, blue, and white (RAL 9002), which is common in medical applications, in addition to black.
