QUICK DECISION
Where this configuration fits.
Check before ordering
The assembly is 618 mm overall and weighs 35 kg. Encoder signals are optional: 1 Vpp sine or TTL square. Confirm what is supplied rather than assuming an encoder is included.
Consider another model
The BT30 GDL120 uses different tooling, a shorter envelope and a different operating point.

INSTALLATION CHECKS
Match the whole assembly.
Start with the exact GDL125-40-12Z/7.5 configuration. Compare the mounting drawing, nose clearance and connection locations with the existing installation. Match the taper, pneumatic release system and sensing requirements before planning the tool-change sequence.
- Check the water circuit and the connector details shown in the drawing.
- Select the documented winding and keep its voltage and current together.
