High precision water-resistant homing sensor

• High accuracy with no moving parts, infrared light sensor. 
• Homing repeatability better than 10 microns.
• Water-resistant with IP65 rating.
• Wide working voltage range 9 to 24VDC.
• 5 metre (16 ft) long high quality flex cable.
• Easy mounting using M3 screws.

CAUTION: Connecting the power polarity in reverse will damage the sensor.

Connections

• BROWN – (9~24VDC)
• BLUE – (0V)
• BLACK – (NO – Normally Open)
• WHITE – (NC – Normally Connected)

Mounting & Triggering mechanism

• Mount the sensor so that it can't get damaged by the operation of the machine.
• It needs to be situated so that when the homing position is reached it is triggered by a metal or any other material trigger plate attached to the machine.
• The sensor works by shooting infrared light from one side of the sensor towards the other receiving side. Any material that blocks this light triggers the sensor and the output signals are changed.
• Ensure the sensor does not receive infrared light from outside sources such as direct sunlight as this may cause false triggering of the sensor.
• The trigger plate needs to pass between the forks of the sensor.
• Mounting dimensions.

Powering your Homing sensors

Power for the homing sensors on MASSO G2 can be provided from:

• Directly from the MASSO power supply distribution point.
• A separate power supply that shares a common ground, (-ve rail), with your MASSO power supply.

Power for the homing sensors on MASSO G3 or MASSO G3 Touch can be provided from:

• Directly from the MASSO power supply distribution point.
• A separate power supply that shares a common ground, (-ve rail), with your MASSO power supply.
• The Auxiliary power terminals are built into MASSO. These are the Red and Black terminals found between the input and output terminals.

WARNING: The installation of a 1 amp fuse between your Power Supply and MASSO is required to protect against an accidental short circuit of the auxiliary power connectors on MASSO, such an event can damage the controller beyond repair.

CAUTION: Auxiliary Power and Ground terminals provided on the controller are only to be used for very low current devices and signals. Connecting high current loads can damage the controller beyond repair.
