Motor temperature sensing KTY84-1C130 (KTY-)
Temperature sensor KTY84-1C130 / PTC
Connector type:
25-pin SUB D connector
Measuring current via temperature sensor connection: 2 mA

NOTICE
Damage to motor in the event of incorrectly connected KTY temperature sensor
A KTY temperature sensor connected with incorrect polarity cannot detect if the motor
overheats. Overheating can cause damage to the motor.
• Connect a KTY temperature sensor with the correct polarity.
