First, the main purpose and scope 
 HFKPT1 series of two wandering open relationship I Company researchers developed a new generation of products, can be used for the detection of conveyor belt run, prevent the belt run off caused by overflow of materials such failure. Conveyor automation control is indispensable sensors. Because this product easy to install, reliable switch, the conveyor belt is widely used. 
 Second, the technical performance and parameters: 
 Model HFKPT1-□ - □ 
 The number of a contact switch is normally open, two normally closed 
 Contact capacity AC 220V 380V ≤ 5A 
 Switching angle a: 10 ° 12 ° 20 °; 2 级: 30 ° 35 ° 45 °; limit angle ≤ 60 ° 
 Relative humidity: ≤ 90% (25 ℃); Altitude: 2000M; Operating Temperature: -30 ~ +40 ℃ 
 Case Material Aluminum 
 Degree of protection IP65 
 Weight (kg) 2.0 
 Interface single outlet port, dual-outlet port can also be customized 
 Third, the structural features: 
 1. This product is cast aluminum housing, high strength, light weight. 
 2. Housing protection grade IP65, can be long-term work in harsh environments. 
 3. This product is sensitive, high stability, performance, reliability, shape structure shown in Figure 5. 

 Fourth, the working principle 
 When the tape transport scene of emergency, can pull on the rope tied to the arm, the arm rotating cam driven by the machine and sensor micro switch, send stop signal. 
 Fifth, installation and adjustment 
 1. The deviation switch fixed on the bracket, and then installed in the tape machine. 
 2. Edger line with the tape perpendicular to the plane, the edge distance of L = 50 ~ 100mm (housing mounting hole can be shifted.) 
 3. Roll up the bottom 1 / 3. 
 4. Deviation for each 100m tape switch that can be installed three pairs (six) See Figure 6.
