Description

Position sensors X125

Linear inductive position sensor

X125

As a leading supplier of linear, rotary, tilt and intrinsically safe position sensors, we have the expertise to supply a sensor to suit

a wide variety of applications. Our X125 LIPS (Linear Inductive Position Sensor) incorporates electronics system EX07 which is

ATEX / IECEx approved for use in potentially explosive gas/vapour atmospheres. The X125 is designed to provide feedback for

mounting options including M8 rod eye bearings and body clamps. The push rod can be supplied free or captive, with male M8

thread, an M8 rod eye, or dome end, Captive push rods can be sprung loaded, in either direction, on sensors up to 300 mm of

travel. The X125 also offers a range of mechanical options, environmental sealing is to IP68 350 Bar.

Specifications (continued)

Intrinsically safe equipment is defined as “equipment which is incapable of releasing sufficient electrical or thermal energy

under normal or abnormal conditions to cause ignition of a specific hazardous atmosphere mixture in its most easily ignited

concentration.”

ATEX / IECEx approved to;

Ex II 1G

Ex ia IIC T4 Ga (Ta = -40°C to +80°C)

Designates the sensor as belonging to; Group II: suitable for all areas

except mining,

Category 1 G: can be used in areas with

certification. The X005 Galvanic Isolation Amplifier is purpose made for this range making it the perfect choice. Refer to the

X005 datasheet for product specification and output configuration options.

Safety Parameters:

Ui: 11.4V, Ii: 0.20A, Pi: 0.51W

Ci = 1.36µF* Li = 860µH* (with cable)
