DIS Sensors produces the popular, non-contact rotary sensor model QR40EMN. Featuring an air gap and zero function, the sensor outputs an absolute 4-20 mA or 5 V signal.
A special version of this sensor, model QR40EMN-360HB-IK2CM-UL, offers the unique ability to zero the sensor no matter what orientation the sensor is mounted in.
These sensors are perfect for OEM heavy equipment. DIS encoders are fully potted and 100% solid state with NO OPTICS inside. You never have to connect the encoder itself to a shaft.
This model can detect rotation through an air gap of 3 mm. This air gap can be filled with any material other than ferrous content.
