ES332 electrospindle sensors

The electrospindle ES332 is fitted with inductive sensors for monitoring its state and a "thermal
alarm" for protecting the electric windings.

6.8.6

ES370 electrospindle sensors

The ES370 electrospindle has a "thermal alarm" to protect the electric windings and inductive
sensors can be fitted (optional) to monitor the correct coupling of the toolholder cone.

NAME

SIGNAL INFORMATION

S1

Tool holder cone coupled

S4

HSK cone coupled and in the correct position

Thermal Alarm

Motor overheated:
stop the electrospindle!

In the case of electrospindle models without sensors it is the customer's
responsibility to monitor its state, with particular attention to the toolholder
coupling.
An imprecise coupling may constitute a serious risk to the operator.

Proximity PNP type Normally Open (N.O.)
Power supply voltage

10 ÷ 30 V (DC)

Maximum load

100 mA

No-load absorption

< 17 mA

Nominal reading distance

1mm
