Combinable M12 control cabinet feed-through connectors

2 mins read

binder, the industrial circular connector manufacturer, has unveiled new control cabinet feed-through connectors for the M12 product series 713, 813, 814, 823 and 824, which are available with different codings and pin count.

The M12 or M12 Power type components, in accordance with the DIN EN 61076-2-111 standard, allow signal, data, and supply cables to be connected using circular connectors of the same type from the respective series. They are equipped with an M12 locking thread and an M16 mounting thread.

M12 connectivity offers efficient, reliable, and cost-effective cabling of fieldbuses, sensors, and actuators in the field of automation technology.

The new binder products are available with A, S, K, L as well as T coding and, depending on the coding, with 4 to 8 pins. In addition, various coding positions can be realised. The coding on each connection side – together with the possibility of freely combining plugs and sockets – ensures the greatest possible degree of freedom during installation.

The technical data of the feed-through connectors, such as protection degree, rated voltage and current, contact resistance, and others, vary from series to series according to the specifications of the respective binder M12 and M12 Power circular connectors. In general, this means that the products meet the requirements of protection degree IP67 and achieve a mechanical lifespan of >100 mating cycles (excluding 713 series). They are designed for operating temperatures between -40 °C and +85 °C (814 series: -25 °C to +85 °C).

In detail, the following specifications apply to the control cabinet feed-throughs: In the case of 3-pin to 8-pin A-coding (713 series), the rated current and voltage depend on the wire cross-section of the corresponding connector and are 2 A at 30 V (8-pin, up to 0.5 mm2, AWG 20) and 4 A at 60/250 V (5-/3-pin, 4-pin up to 0.75 mm2, AWG 18), respectively. The rated impulse voltage is 800 V and 1500/2500 V, respectively. The mechanical lifespan is specified as >100 mating cycles (8-pin, up to 0.5 mm2, AWG 20) or >50 mating cycles (5-pin, 4-pin and 3-pin, up to 0.75 mm2, AWG 18).

The control cabinet feed-throughs of the 4-pin T-coded 813 series are specified for a rated current of 12 A at 63 V(DC). The rated impulse voltage here reaches 6000 V. For the S-coded 814 series, the rated current, voltage and impulse voltage are specified as 16 A (pin count 2+PE, PE – Protective Earth) and 12 A (3+PE) as well as 630 V and 6000 V, respectively.

The 823 series with L-coding – pin count 4+FE (Functional Earth) – is specified for 16 A at 63 V(DC), for 1500 V rated impulse voltage as well as with ≤5 mΩ. The corresponding circular connectors of this series have been designed for wire gauges/cross-sections of 1.5 mm2 (AWG 16) with ferrule or for 2.5 mm2 (AWG 14) without ferrule.

The feed-throughs of the K-coded 824 series are available with 3+PE pins. They are rated 12 A at 630 V and withstand impulse voltages of up to 6000 V.
