Limited installation space is a recurring constraint in mouldmaking, where every millimetre affects assembly and operation. Hasco has released the plug insert H12294 for 12 control zones, designed to utilise available space without compromising electrical performance. Despite the increased connection density, the insert retains a maximum load capacity of 16 A. It is intended to replace large, complex connection boxes with a compact interface, while keeping the mounted housing identical to earlier 6-zone variants. A key benefit of the design is that only half of a bulkhead mounted housing is required. This can be advantageous in small, compact moulds and also in large multi-cavity injection moulding tools, in which connection boxes often protrude from the mould and complicate assembly. By shrinking the footprint of the connection hardware yet maintaining current-carrying capability, the insert addresses typical integration challenges in hot runner-equipped tools.
Crimp-based connectivity
The plug insert uses crimp technology to secure cables. The wires are permanently compressed in the pins, providing a reliable connection, yet can be removed from the plug with the appropriate tool for rewiring when required. This approach enables fast changes to wiring layouts and is intended to support safety, reliability and long service life.
Cables and wiring options
To complement the insert, Hasco Hot Runner supplies coordinated cables. On request, these can be provided as a connecting cable with compact pin assignment on one side and the usual wiring on the other, allowing existing control technology to continue in use without modification. If a different wiring standard is needed, it can be specified at the time of order. Hasco Hot Runner manufactures these connecting cables, as well as its broader cable portfolio, to customer-specific requirements.
According to the company, combining the 12-zone insert with matched cabling offers a space-saving setup that can make day-to-day production more efficient and less expensive, citing approximately 75% less wiring time.
