Description
LDA-196-1000CE
Technical Specifications Brand: Linear Displacement Series Model: LDA-196-1000CE Measurement Stroke: 1000 mm Output Signal: 4-20 mA analog signal Power Supply: 24 VDC Repeatability: 0.01% full scale Linearity: ±0.05% full scale Operating Temperature: -20°C to +70°C Protection Grade: IP67 Mounting: Two end bracket mounting Cable: Integral shielded output cable
Functional Features Continuous linear position measurement across full 1000 mm stroke. Onboard signal conditioning converts internal resistance change to standard 4-20mA current output. High linearity and repeatability ensure reliable position reading for control system. IP67 sealed housing withstands dust, moisture and splash in factory environment. Shielded cable reduces electromagnetic interference impact on measurement signal. End mounting brackets simplify installation on machine frame and moving slide.
Application Scenarios Hydraulic cylinder position feedback, press machine ram position monitoring, gate valve stroke measurement, conveyor position tracking, construction machinery linear position detection, material thickness control system.
Performance Parameters Output signal varies linearly with measured mechanical displacement. High repeatability ensures consistent reading for repeated position. Strong resistance to industrial electromagnetic noise. Waterproof and dustproof structure works in wet workshop environment. Long service life under reciprocating sliding motion.
Material Composition Outer Tube: Anodized aluminum alloy. Internal Measuring Core: Stainless steel. Sealing Components: Fluorine rubber O-rings and wiper seals. Internal Resistive Element: Conductive plastic resistive track. PCB: FR4 printed circuit board for signal conditioning. Cable: Shielded PUR insulated multi-core cable.
Structural Features Long tubular housing with sliding internal core rod. Wiper seal at front opening cleans rod surface during movement. End mounting lugs on both ends of sensor tube. Internal conductive plastic track contacts with sliding wiper connected to core rod. Signal conditioning PCB sealed inside sensor end cap.
Working Principle Mechanical movement pushes or pulls the stainless steel core rod. The wiper on core rod slides along conductive plastic resistive track, changing resistance value proportional to travel distance. The integrated signal conditioning circuit converts resistance variation into standard 4-20mA current signal. Connected controller reads current value and calculates linear position of the core rod.
Installation Requirements Fix sensor tube body on stationary machine frame and connect core rod to moving target. Keep core rod aligned with movement direction to avoid side load on rod. Route shielded cable separately from high voltage power cable. Connect 24 VDC power supply with correct polarity. Calibrate zero and full scale position after mechanical installation.
Usage Notes Avoid lateral force and side load on core rod, side load damages wiper and resistive track. Prevent mechanical overtravel beyond rated stroke, overtravel destroys internal components. Protect cable from sharp cutting edges and heavy pull force. Inspect wiper seal regularly for dirt buildup. Do not disassemble sealed sensor housing.
