Connections

Motor connection9-pin, straight or angled
Sensor connection17-pin, straight or angled (for MTC / QTC from the second sensor onwards)
Coolant connection2 × push-in fitting Ø 8 mm (Win inlet / Wout outlet) – liquid cooling only
Pneumatic connection3 × push-in fitting Ø 6 mm (LD / PR / KBL) – automatic tool change only
