Contact-Type Displacement Sensor

A contact-type displacement sensor is a precision measurement device that detects changes in position or displacement by making direct contact with the measured object. Unlike non-contact sensors, it eliminates potential interference from environmental factors such as light, dust, or electromagnetic fields, ensuring high accuracy and stability. These sensors typically operate based on optical (grating), inductive, resistive, capacitive, or piezoelectric principles, converting physical displacement into electrical signals for precise measurement.

GFJ series

The GFJ series contact-type displacement sensors are precision measurement devices designed for industrial applications. They feature an absolute measurement system with a resolution as fine as 0.2μm and accuracy within ±2μm. These sensors support RS485 communication using the Modbus RTU protocol and offer response times under 50ms. With a measurement range of 0-12.7mm to 0-25.4mm and a working temperature range of -10°C to +50°C, they are ideal for high-precision tasks in automation and industrial safety solutions. Their IP65 rating ensures protection against harsh environments, making them reliable for long-term use.

GFK & GFW Series

The GFK & GFW series contact digital displacement sensors are high-precision devices for industrial measurement applications. They feature a measurement range from 1mm to 10mm, with resolutions as fine as 0.1μm and repeat accuracy within ±1μm. These sensors support RS485 communication with a Modbus RTU protocol. Designed for reliability, they operate within a temperature range of -10°C to +60°C and provide IP65 protection. Ideal for measuring displacement, vibration, thickness, and runout, these sensors are perfect for automotive parts, bearings, gears, and electronic product housings, ensuring precise and efficient performance in industrial automation.
