Digital plug gauge contact type displacement sensor (SA series)

It is a high-precision contact displacement sensor that detects the absolute position of the spindle with a high-resolution optical method. It is used in length measurement systems by combining with an optional SA series controller. By supplying air to the main body of the detector and increasing the internal pressure, it is possible to prevent the intrusion of foreign matter from the outside and greatly improve the environmental resistance. It is also air that can be used in harsh environments such as high permeability oil, coolant, and processing lubricant. Purification products.

High precision counting
Advanced absolute method

The sensor uses the optical absolute encoder method.
In this way, the absolute position can be read immediately and saved even if the power is turned off.
This eliminates the need to adjust the zero position when the power is turned on, and saves the time required for setting.

Reduce the risk of damaging the sensor shaft

There is no bearing inside the valve stem, which reduces the damage caused when the stem is tightened. In addition, a plug is used in the valve stem to reduce internal damage caused by stroke overload. The improved anti-rotation mechanism provides significantly improved lateral bearing capacity and impact resistance.

Reduce stroke overload errors

The stroke overload is caused by various factors, including human error and accidental factors, which are detected and automatically output errors.

When the stroke overload is detected, the equipment immediately stops to avoid unnecessary problems.

Easy to remove and connect wires

The connector head is threaded to prevent the connector from falling off, and the wire connector can be easily removed and connected.
In addition, L-type and straight-type connectors are also available depending on the purpose used.
Easily identify errors with LED indicators

For the first time, the sensor uses an LED indicator. The pass/fail judgment result can be recognized at a glance by just looking at the detector.
Easy-to-remove fastening type connector

The SA series cables use tight connectors, which can be easily connected and disassembled at your work site. The sensor has an L-shaped connector and a straight connector required for some applications, which provides greater flexibility.
