TBT1A    Rotation Speed Sensor

Application
TBT1A rotation speed sensor is a magnetoelectric rotation speed sensor, and it is installed t
the case or case cover of transmission gear, the tested rotary object is magnetic conductibility gea
which has two signaling hole with diameter 4 mm(depth 3 mm). It is composed o
permanent-magnet steel, electrical inductance coil, shell, shield cable, connector, etc. Outpu
signal is similar to sine wave, adapting operation with other speed measuring control equipment i
the various transport facilities. The sensor can detect the rotational speed of transmission gear an
the speed of transport, applicable to various transport facilities.  

Features
Wide temperature accommodation
Wide speed measuring range
Strong shock resistance
Good tightness
Non-contact with tested gear, without abrasion
Convenient installation, simple and reliable

The definition of cable & connector output function  

Installation\operation and malfunction disposal   Forbidden contact between terminals; otherwise the permanent-magnet would be
demagnetized greatly, even damaged.     Output wire distribution as per the definition strictly, and ensure it correct, without short
and open circuit;   Strong recommend the air gap between gear and the head of sensor is adjusted to 1.0
mm,after adjusting the air gap, tighten these four fixed screws;   When check the sensor, use the multimeter to measure DC resistance (connector pin1
and pin 3 or pin 2 and pin 4), the resistance should comply to 850?±10%, which shows the sensor
work normally.
