Explosion Proof Draw Wire Displacement Sensor 0 to 6000mm

1. Description

JW-EPD(S15) Explosion Proof Draw Wire Displacement Sensor 0 to 6000mm is designed for linear position measurement in industrial environments where reliable displacement feedback and durable construction are required. It supports multiple output options, offers 0.08% linearity, and is suitable for equipment positioning, stroke measurement, gate control, hydraulic machinery, and other automation applications.

2. Product Overview

JW-EPD(S15) explosion proof draw wire displacement sensor, also known as an explosion proof cable extension sensor or draw wire encoder, is used to convert linear movement into electrical signals for displacement monitoring and position control. It is suitable for applications that require compact installation, long measuring stroke, and stable output in industrial environments.

The sensor supports multiple output types, including analog, resistance, pulse, and digital communication signals, making it easy to integrate with PLCs, controllers, display instruments, and industrial automation systems. With a measuring range of up to 6000mm, 0.08% linearity, IP65 protection, and a wide operating temperature range, it provides reliable performance for motion feedback and precise positioning tasks.

5. Installation Notes

Use the four fixing holes on the mounting bracket or base and choose the correct installation orientation according to the available equipment space.
During installation, keep the wire rope movement direction aligned with the rope outlet as much as possible. Minimize angle deviation, with a recommended tolerance of about ±3°, to maintain measurement accuracy and wire rope service life.
For vertical long-stroke applications, it is recommended to install the sensor body at the lower position and pull the wire rope upward.
The wire rope is made of stainless steel. Avoid external cuts, welding sparks, impacts, excessive dust, debris buildup, and corrosive environments.
Before the sensor is fixed on the workbench or base, do not pull out the wire rope by hand or other objects and allow it to retract suddenly, as this may damage the rope, the sensor body, or cause injury.
For non-linear motion applications, use a suitable pulley or guide mechanism to convert the movement into linear travel.
The operating speed should remain within the recommended limit to avoid reducing reliability and service life.
