1、Product Features

◦ Solid and flexible design

◦ Die-cast aluminum alloy or stainless steel shell; all external fastening metal parts are made of stainless steel

◦ Built-in visual position indicator for clear identification of the switch position

◦ Quick-set cam

◦ Spring-loaded splined cam - no adjustment required after initial setup; tool-free configuration

◦ Dual or multiple cable entries

◦ Anti-loose bolt (FL-5) - the bolt attached to the upper cover will not fall off during disassembly and assembly

◦ Easy installation

◦ Connecting shaft and mounting bracket comply with NAMUR standards

2、Display

◦ Multiple types of display windows available

◦ Reinforced polycarbonate material

◦ Standard 90° display (180° optional)

◦ Distinctive standard colors: green for "Open" and red for "Close" (yellow-red or customized colors optional)

3、Housing

◦ Materials: aluminum alloy, stainless steel 316SS/316L

◦ Robust and compact structure, with flat mating surfaces, zigzag mating surfaces or threaded mating surfaces that meet explosion-proof and protection requirements (FL-5 Series)

◦ Standard configuration: 2 electrical interfaces (up to 4 optional, with specifications including NPT, M20, G, etc.)

◦ O-ring seals available in nitrile rubber, EPDM, fluororubber and silicone rubber

4、Stainless Steel Shaft

◦ Configurations: NAMUR standard or customer - customized

◦ Anti-flying-out shaft design (flameproof type FL - 5N)

◦ Operating temperature range: conventional ranges of -25°C ~ 60°C and -40°C ~ 60°C; optional range of -55°C ~ 80°C

◦ Protection class: IP66/IP67, IP68 optional

5、Anti-corrosion Treatment for Explosion-proof Surfaces and Shell Surfaces

◦ Corrosion resistance grade: above WF2; withstanding 1000 hours of neutral salt spray test

◦ Treatment method: DuPont resin + anodizing + anti - ultraviolet coating

6、Schematic Diagram of Internal Composition

◦ Unique meshing design enables quick and accurate adjustment of the sensor's sensing position. The switch position can be easily set to the middle. The dense upper and lower meshing gear design effectively prevents deviation caused by vibration and ensures signal stability. High - precision gears combined with high - precision cams achieve micro - angle differentiation (deviation less than +/-2%).

◦ The upper cover is tightly connected to the shaft, which prevents water and contaminants from entering the cavity when the indicator is damaged and ensures normal operation for a certain period.

◦ Internal metal parts (including the main shaft): made of stainless steel

◦ Terminal block: standard 8 - position terminal block (12 - position optional)

◦ Anti - static measure: internal grounding terminal

◦ Sensor or microswitch: mechanical type/inductive proximity type/magnetic proximity type

◦ Internal anti - corrosion treatment: anodizing/hardening

◦ Internal wiring: circuit board (FL - 5 Series) or wiring harness

Solid and durable aluminum die-casting. 20  sets  of terminals to the maximum. Cams loaded with spring,the limit position can be easily set without tools.     The domed  indicator with high visibility has a double-sealed construction,which  prevents water inflow in the event of dome failure.   There  are  several  additional  options  to  choose  from.
