BRG-60 Explosion-proof Series Cable Displacement Sensor
BRG-120FB series wire displacement sensor (hereinafter referred to as sensor) is mainly used to measure the displacement of wire through pulse signal in DC24V line in explosive gas environment of Class IIA, IIB, IIC, T1~T6 in Zone 1 and Zone 2.


- The altitude does not exceed 2000m;
- The operating environment temperature is -20~+40℃;
- The relative humidity of the surrounding air is not more than 98% (when the temperature is +25℃);
- It is suitable for explosive gas environments of Zone 1, Zone 2, Class IIA, IIB, and IIC T1~T6;
- The installation slope with respect to the vertical plane is not more than 5°;
- In a place without significant shaking and impact vibration;
- A place that can prevent dripping water and other liquids from intruding;
- Pollution level 3;
- Installation category II.

Installation Dimension (mm)

Alignment – Maintain wire perpendicularity to the encoder; avoid outlet friction.
Secure Mounting – Firmly fix both sensor and moving end to prevent loosening or spring rebound.
Wire Handling – Never release a tensioned wire abruptly or exceed max extension length.
Electrical Safety – Verify wiring per sensor diagram before powering on.
Precision Care – Avoid impacts; keep sensor and wire clean for optimal longevity.
Wire Protection – Prevent crushing, bending, or other mechanical damage.
Harsh Environments – Contact us for IP-rated outlets or protective enclosures.
