Stainless steel deviation switch PXA-02GKH-A stainless steel deviation switch PXA-02GKH-A stainless steel deviation switch PXA-02GKH-A1. The deviation switch is located on both sides of the conveyor belt, and the vertical roller should be perpendicular to the edge plane of the conveyor belt, and the two sides of the conveyor belt should be located at 1/3 of the height of the vertical roller. The distance between the vertical roller of the deviation switch and the normal position of the conveyor belt should be 50-100mm. The number of deviation switches should be determined based on the length, type, and layout of the conveyor. Generally, it should be set at the head, tail, convex arc section, concave arc section, and in the middle position of the conveyor. (Note: When the conveyor is long, one pair can be installed every 30-35 meters in the middle position of the conveyor.) 4. The deviation switch should be connected to the middle frame of the conveyor through an installation bracket. The switch bracket should be welded to the conveyor frame after the conveyor is installed. The deviation switch and the deviation switch bracket should be fixed with bolts& nbsp; The two-stage deviation switch consists of a hard contact and an address encoding circuit. Two micro switches are used for the first level deviation alarm hard contact and the second level deviation alarm hard contact, respectively, for the conveyor deviation alarm and emergency stop. When the address encoding two-stage deviation switch acts, the address encoding circuit will immediately send alarm information and address encoding through the communication circuit. Technical indicators; Environmental temperature: -30 ℃ -+70 ℃; Relative humidity: not more than 85%. The first level action angle is 12 degrees; （15°）； Second level action angle 30° （35°）； Extreme angle 70°< Number and capacity of contacts: 2 sets of normally open; 2 groups are normally closed; 5A/AC 380V
Protection level: IP67
Reset method: automatic reset
Reliability> 1000000 times; The classification of deviation switches includes ordinary type, wiring chamber type, and address coding type. The ordinary type refers to the two-stage deviation switch mentioned above; The wiring chamber type deviation switch is equipped with a waterproof wiring chamber on the basis of the ordinary type deviation switch. The on-site control cable can be directly connected to the wiring chamber to prevent faults caused by moisture and virtual connection of cable joints. The address encoding type deviation switch integrates XLline fieldbus technology on the basis of ordinary deviation switches, achieving address encoding function. Suitable for remote monitoring of the operation of long belt conveyors as on-site equipment, it solves the inconvenience caused by workers searching for fault points. The address encoded two-level deviation switch is connected to the comprehensive protection device (gateway) through XLline fieldbus, supporting up to 128 addresses, and multiple switches can be used simultaneously at the same address. Its main feature is that it only requires a two core cable to complete data transmission simultaneously without the need for power supply. XLline fieldbus can finally achieve flexible connection with major manufacturers' PLCs and computer interfaces& nbsp; Armored platinum resistor WZPK-466U, WZPK-563U，WZPK-564U，WZPK-565U，WZPK-566U，.WZPK-173U，WZPK-174U，WZPK-175U，WZPK-176U，WZPK-273U，WZPK-274U，WZPK-275U，WZPK-276U，WZPK-373U，WZPK-374U，WZPK-375U，WZPK-376U，WZPK-473U，WZPK-474U，WZPK-475U，WZPK-476U，WZPK-573U，WZPK-574U，WZPK-575U，WZPK-576U，WZPK-103S，WZPK-104S，WZPK-105S，WZPK-106S，WZPK2-105SA，WZPK2-106SA，WZPK-203S，WZPK-204S，WZPK-205S，.WZPK-206S，WZPK2-205SA，WZPK2-206SA，WZPK-303S， Chemical explosion-proof thermal resistance WZPK-304S, WZPK-305S，WZPK-306S，WZPK2-305SA，.WZPK2306SA，WZPK-403S，WZPK-404S，WZPK-405S，WZPK-406S，WZPK2-405SA，WZPK2406SA，WZPK-503S，WZPK-504S，WZPK-505S，WZPK-506S，WZPK2-505SA，WZPK2506SA，WZPK-123S，WZPK-124S，WZPK-125S，WZPK-126S，WZPK2-125SA，WZPK2-126SA，WZPK-223S，WZPK-224S，WZPK-225S，WZPK-226S，WZPK2-225SA，WPK2-225SA，WZPK2-226SA，WZPK-323S，.WZPK-324S，WZPK-325S，WZPK-326S，WZPK2-325SA，WZPK2326SA，WZPK-423S，WZPK-424S，WZPK-425S，WZPK-426S，WZPK2-425SA，.WZPK2426SA，WZPK-523S， Explosion proof platinum resistor WZPK-524S, WZPK-525S，WZPK-526S，WZPK2-525SA，WZPK2526SA，WZPK-133S，WZPK-134S，WZPK-135S，WZPK-136S，WZPK2-135SA，WZPK2-136SA，WZPK-233S，WZPK-234S，WZPK-235S，WZPK-236S，WZPK2-235SA，WZPK2-236SA，WZPK-333S，WZPK-334S，WZPK-335S，WZPK-336S，WZPK2-335SA，WZPK2336SA，WZPK-433S，WZPK-434S，WZPK-435S，WZPK-436S，WZPK2-435SA，WZPK2436SA，WZPK-533S，WZPK-534S，WZPK-535S，WZPK-536S，WZPK2-535SA，WZPK2536SA，WZPK-163S，WZPK-164S，WZPK-165S，WZPK-166S， Platinum resistance element WZPK2-165SA, WZPK2-166SA，WZPK-263S，WZPK-264S，WZPK-265S，WZPK-266S，.WZPK2-265SA，WZPK2-266SA，WZPK-363S，WZPK-364S，WZPK-365S，WZPK-366S，WZPK2-365SA，WZPK2366SA，WZPK-463S，WZPK-464S，WZPK-465S，WZPK-466S，WZPK2-465SA，WZPK2466SA，WZPK-563S，WZPK-564S，WZPK-565S，WZPK-566S，WZPK2-565SA，WZPK2566SA，WZPK-173S，WZPK-174S，WZPK-175S，WZPK-176S，WZPK2-175SA，WZPK2-176SA，WZPK-273S，WZPK-274S，WZPK-275S，WZPK-276S，WZPK2-275SA，WZPK2-276SA，WZPK-373S，WZPK-374S，WZPK-375S，WZPK-376S，WZPK2-375SA，WZPK2376SA，WZPK-473S，WZPK-474S，WZPK-475S，WZPK-476S，WZPK2-475SA，WZPK2476SA，WZPK-573S，.WZPK-574S， WZPK-575S，WZPK-576S，WZPK2-575SA，WZPK2576SA，WZPM-101U，WZPM-201U，WZPM—002U，WZPM-102U，WZPM-202U，WZPM—001，WZPM-101S，WZPM-201S，WZPM-002，WZPM-102，WZPM-202，WZPM—301，WZP-011S，WZP-012S，WZP-013S，WZP-014S，WZP-015S，WZP-203S，WZP-205S，WZP-018，WZP-0110，WZP-2012， Intermediate relay DZS-895, DZS-894，DZS-893，DZS-892，DZS-891，DZ-655，DZ-654，DZ-653，DZ-652，DZ-651，BZS-14，BZS-13，BZS-12，BZS-11，DZJ-12，DZJ-11，DZS-145，DZS-136，DZS-127，DZS-117，DZS-115，DZB-138，DZB-136，DZB-127，DZB-115，DZ-3/Z5，DZ-3/Z4，DZ-3/Z3, DZ-3/Z2, DZ-3/Z1,JZ15，JZ11，JZ14，JZ8，ZJ6，ZJ5，ZJ4，ZJ3-E，ZJ3-C，ZJ3-B，ZJ3-A，ZJ2, YZJ1，DZK-900，DZS-894，DZ-700E，DZ-700，DZ-650，DZ-432，DZ-431，DZK-300Q，DZK-300T，DZS-17E，HZS-313，HZB-313，HZK-311，HZL-301，HZJ-301，HZY-301，DZ-200，BZS-10，HZS-26，HZS-25，HZS-24，HZS-23，HZS-22, HZS-21, HZB-25, HZB-24, HZB-23, HZB-22, HZB-21, DZS-10CE，DZS-10B，DZB-10CE，DZB-10B，DZJ-20，DZJ-10，DZ-30CE，DZ-30B，HZS-145，HZS-127，HZS-117，HZS-115， HZB-138，HZB-127，HZB-115， HZ-17，HZ-16，HZ-15，DZ-17，DZ-16，DZ-15，DZ-50，DZ-3E/J，DZ-3E，DZ-3/Z，ZJ3-BH，ZJ3-1B，ZJ3-2B，ZJ3-3B，ZJ3-4B，ZJ3-5B，ZJ3-1A，ZJ3-2A，ZJ3-3A，ZJ3-3A，ZJ3-5A，ZJ2-4，ZJ2-3，ZJ2-2，ZJ2-1，ZJ1-2，ZJ1-1，YZJ1-5，YZJ1-4，YZJ1-3，YZJ1-2，YZJ1-1，DZ-32B，DZ-31B，DZS-16B，DZS-15B，DZS-14B，DZS-13B，DZS-12B，DZS-11B，DZB-15B，DZB-14B，DZB-13B，DZB-12B，DZB-11B，DZK-942，DZK-938，DZK-937，DZK-936，DZK-918，DZK-917，DZK-916，DZK-934，DZK-924，DZK-914，DZK-912，DZK-911，DZK-254，DZK-244，DZK-236，DZK-226，DZK-216，DZK-214，DZK-211，DZS-254，DZS-249，DZS-248，DZS-236，DZS-233，DZS-229，DZS-216，DZS-213，DZB-284，DZB-278，DZB-262，DZB-259， DZB-257，DZB-243，DZB-233，DZB-228，DZB-226，DZB-217，DZB-214，DZB-213，DZL-222，DZL-221，DZL-220，DZL-219，DZL-218，DZL-217，DZL-216，DZL-215，DZL-214，DZL-213，DZL-212，DZL-211，DZL-210，DZL-209，DZL-208，DZL-207，DZL-206，DZL-205，DZL-204，DZL-203，DZL-202，DZL-201，DZJ-222，DZJ-221，DZJ-220，DZJ-219，DZJ-218，DZJ-217，DZJ-216，DZJ-215，DZJ-214，DZJ-213，DZJ-212，DZJ-211，DZJ-210，DZJ-209，DZJ-208，DZJ-207，DZJ-206，DZJ-205，DZJ-204，DZJ-203，DZJ-202，DZJ-201，DZY-222，DZY-221，DZY-220，DZY-219，DZY-218，DZY-217，DZY-216，DZY-215，DZY-214，DZY-213，DZY-212，DZY-211，DZY-210，DZY-209，DZY-208，DZY-207，DZY-206，DZY-205，DZY-204，DZY-203，DZY-202，DZY-201，3TH82-62， 3TH82-44，3TH80-40， JZ17-44，JZ7-62，JZ7-80，JZ7-44，JDZ2，JJDZ3-33，522， Voltage relay JY-40UC, JY-40C，JY-40UB，JY-40B，JY-40UA，JY-40A，DY-38，DY-37，DY-36，DY-35，DY-34，DY-33，DY-32，DY-31，DJ-132，DJ-122，DJ-112，DJ-131，DJ-121，DJ-111，BZY-1，BFY-10A，JY-3/2，JY-3/1,DY-4，LY-1A，JCDY-2A，JCDY-2, JY-40, HY-30，HY-20，HY-10，JY-30，JY-20，JY-10，LY-30，DY-
