Multi-position A-coding facilitates flexible and fault-free use

Update: November 19, 2021

binder provides multiple A-coded M12 connectors as part of its 763 product series, which are furnished with a square-flange housing for assembly. As a unique feature, the multi-position A-coding supports variable cable connections. Also beneficial for flexible use is the flange housing and contact carrier that may be processed separately.

The square-flange variants of the series comprise of two parts: the metal flange housing and a contact carrier. The latter is provided with a lockable coding nose that may be rotated in 45-degree increments. The two-part design supports user-friendly, safe assembly.

The series comprises M12 A signal connectors equipped with four, five and eight pins and single wires or solder contacts. The single-wire version offers a square housing of 20mm or 26mm wide. In the version with solder contacts, it measures 20mm. The 26mm square housing of the M12 single-wire version has the same drilling scheme as the M16 form factor. This enables users to swap between the design sizes without adapting existing housings, such as sensor/actuator boxes.

The rectangular-flange M12 connectors with multi-position, lockable A-coding are specified for a maximum wire gauge of 0.25mm2 (AWG 24). In all four-pin and five-pin versions, the rated currents reach 4A (3A UL), 2A (1.5A UL) with eight. The rated voltages are 250V (four-pin), 60V (five-pin) and 30V (eight-pin). The corresponding rated impulse voltages are specified as 2500V, 1500V and 800V, respectively. The connectors satisfy the density requirements – combined with suitable sealing but without a defined tightening torque – in accordance with protection degree IP69. They are intended for operating temperatures from -40C to +85C.
