Pen-Type Contact Displacement Sensor

DHGT-P Series

DHGT-P Series

The P Series pen-type contact displacement sensor features a compact and lightweight pen-style design with a total weight of approximately 35 g (excluding cable). It is ideal for automation equipment and precision inspection applications where installation space is limited.

Based on the same measurement principle and performance as the H12 series, the sensor adopts sealed absolute-position optical grating encoding technology to ensure stable and reliable high-precision displacement measurement across the entire measuring range.

The robust structure with IP67 protection ensures stable operation even in harsh industrial environments such as oil contamination and coolant splashes.

Product Features

Compact & Lightweight Design

The pen-style structure weighs approximately 35 g (excluding cable), offering a compact and lightweight design that allows easy integration into space-constrained automation equipment and compact inspection systems.

High Precision & Stable Measurement

With 0.1 μm resolution and 1 μm (P-P) absolute accuracy, the sensor precisely detects micro-scale displacement changes, meeting the requirements of precision assembly and inline inspection.

High-Speed Response

With a minimum sampling cycle of 1 ms and a mechanical response frequency of 10 Hz, the sensor enables real-time displacement acquisition for high-speed and high-frequency inline inspection applications.

Industrial-Grade Reliability

Featuring a high-hardness linear ball bearing structure, the probe supports up to 200 million measurement cycles. Combined with IP67 protection and an operating temperature range of -10°C to +55°C, it ensures reliable operation in demanding industrial environments.
