Instrument box SQX-2B
 
1. ■ SQX-2B type
 
1. SQX-2B lifting weight limiter is composed of two parts: sensor and electrical control instrument. It is a safety protection device widely used in cranes, door cranes and hoisting equipment. The main technical indicators of the limiter are better than those of GB12602-90 "Lifting Machinery Overload Protection Safety Device" as follows:
 

No	name and model	skills requirement
1	Precision	Display accuracy≤5%F, S, action error≤3%F, S (full load)
2	Pre-alarm	90% of the rated lifting capacity will give an audible and visual alarm
3	Delayed alarm	105% of the rated lifting capacity continues to sound and light alarm, delay 1-2 seconds relay action, cut off the lifting power supply.
4	Call the police immediately	The 130% relay of the rated lifting capacity will act immediately to cut off the lifting power supply.
5	Power supply	220V or 380VAC, 50Hz
6	working environment	-20% ~ +60%, ≤90%RH.
7	Protection level	The sensor is IP65 and the instrument box is IP42.
8	Sensor overload capacity	1.5 times the rated lifting capacity.
