Weidmüller is expanding its WGK range of feed-through terminals with the introduction of the suitable-for-potting feed-through device terminals VWGK 4 and VWGK 6. VWGK device terminals are available for the cross-section range 4 and 6 mm². The device terminals are designed to terminate conductor sizes 0.5-6mm² and 0.5-10mm². The lateral dovetail interlocking system means creating a block of terminals poses no problems. VWGK are available in grey or green/yellow - the green/yellow versions do not have an equipment grounding function.

All variants have a uniform 10-mm pitch hole pattern. The user-friendly connection on the customer-side is made utilising the proven clamping yoke connection; a solder hook is provided on the inside for solder termination. The terminal is fixed to the inside of the housing by means of a plastic knurled nut. VWGK terminals are insulated and prevent any leakage of the compound material. For the terminal housings Weidmüller uses the insulating material WEMID. This is a special thermoplastic from Weidmüller with an enhanced continuous operating temperature of +120 °C in comparison with polyamide PA 66 (PA 66: 100 °C). At the same time it exhibits improved fire resistance qualities - flammability class V0 (PA 66: V2) in accordance with UL 94. Weidmüller's clamping yoke system works on the principle of 'steel for strength and copper for current'. Made of zinc plated, additionally chromate coated and case-hardened steel the clamping yoke and the high-tensile clamping screw fix the conductor firmly in place in the termination point.

The unceasing high-contact force applied to the conductor ensures a gas-tight, vibration- and jolt-proof connection. The connection is maintenance-free, which means there will be no need to re-tighten the screw in future. VWGK terminals are a choice for device manufacturers requiring connection solutions for EMC filters, power supplies and coil assemblies. The feed-through device terminals are suitable for use in double insulated transformers and encapsulated filter modules. VWGK device terminals (500 V/41 A) can be deployed in ambient temperatures ranging from -40 to +75 °C, plus 45 °C self-heating when under current load. All VWGK feed-through device terminals are predestined for use in applications across the globe as documented by approvals in accordance with IEC 60947-7-1, UL 1059 and CSA.
