DF1 series travel switch - limit switch operating arm's maximum speed
The maximum speed of the lever operated arm is 200m/min, and the minimum speed is 5m/min;
The maximum speed of the fork operated arm is 100m/min, and the minimum speed is 3m/min.

Overview of the main structure of DF1 series travel switch

The limit switch is mainly composed of a contact group, a rotating shaft, a housing, etc. The shell is made of cast aluminum parts. The contact breaking of the limit switch is achieved by driving the rotating shaft with the operating arm, causing the cam on the rotating shaft to move. The cam and adjustment sleeve on the shaft are uniformly equipped with 24 teeth on the circumference of the diameter 26. The cam angle can be adjusted as needed to achieve the desired closing program. When adjusting, simply remove the screws on the end cover and adjustment sleeve. The rocker arm can also be adjusted freely within 360 degrees (every 15 degrees). The limit switch has 2 sets of contact groups.

model	explanation and illustration
DF1-A	Rod type manipulator arm automatic reset type, abbreviated as rod type
DF1-B	Fork type manipulator arm non automatic resurrection position type, abbreviated as fork type

Operation and Maintenance
Operate the limit switch operating arm according to the required opening and closing procedures, observe whether the opening and closing of the contacts are the same as the required opening and closing procedures, and adjust them if they do not match. All screw connections must be sturdy, especially the contact group wiring screws. The friction part should have some lubrication. The maximum movement angle of the lever operated arm is 45 degrees clockwise and counterclockwise respectively, and the movement angle required to close the program is 25 degrees clockwise and counterclockwise respectively; The maximum movement angle of the fork type manipulator arm is 90 degrees clockwise or counterclockwise, and the movement angle required to achieve the required closing program is 50 degrees clockwise or counterclockwise.

Structural Overview
The travel switch is made of a steel shell, with one normally open and one normally closed contact. Under normal circumstances, the opening distance of the contact is 4-5mm, and the excess travel is 2mm. The operating arm 1 rotates left and right under external force, pushing the internal operating rod 2 to achieve the opening and closing of the contact The left and right rotation angles of the operating arm are approximately 45 degrees

Operation and Maintenance
The travel switch is fixed with 2 M8 screws Open the upper cover and manually push the operating arm 1 to rotate left and right to see if it rotates flexibly At the same time, observe the opening and closing of the contacts and the contact situation. If the contacts cannot achieve the above-mentioned opening distance and excess travel, adjustments should be made
The travel switch should be checked regularly to maintain the flexible rotation, reliable reset, and reliable opening and closing of the operating arm 1

2026-6-16 19:46:07

Action principle:
The JW2/JW2A series travel switch components adopt a pair of moving contact contacts, a pair of moving contact contacts, and a common jumping contact bridge. Under the action of external force (collision block), the contact uses the tension of the spring to make the dynamic contact and dynamic disconnection switch; When the external force disappears, it will automatically reset with the help of the spring's restoring force.
Standard:
Compliant with standards such as GB/T14048.1 and GB14048.5
Purpose:
JW2 and JW2A series travel switches can convert mechanical motion into electrical signals, suitable for control circuits with AC 50Hz or 60Hz, voltage up to 220V and DC voltage up to 220V and below, and current of 3A (overseas products can be used for AC up to 500V and DC up to 440V), used to control travel.
