Product Description
CHINT YBLX-ME Series Travel and Limit-Switch Actuating Head Plunger, Rotating Arm, Roller, Free Divection
Mechanical limit switches are contact sensing devices widely used for detecting the presence or position of objects in industrial applications. The term limit switch is derived from the operation of the device it-self. As an object (or target) makes contact with the operator of the switch, it eventually moves the actuator to the "limit" where the elec-trical contacts change state.
Through this mechanical action, electrical contacts are either opened (in a normally closed circuit) or closed (in a normally open circuit). Inductive proximity, capacitive proximity, and photoelectric sensors perform this same process through non-contact sensing.
Features and Benefits of Limit Switches
Can be used in almost any industrial environment
Very precise in terms of accuracy and repeatability
Consume little electrical energy
Can switch loads with high inductance
Can control multiple loads
Limitations of Limit Switches
Generally restricted to equipment operating at relatively low speeds.
Must make direct contact with target.
Moving mechanical parts will wear out.
Limit Switch Terminology
Pretravel — the distance or angle that the actuator must go through to trip the contacts
Operating Point — position of the actuator at which the contacts snap to the operated position
Release Point — the position of the actuator at which the contacts return to their original state
Differential — distance (degrees) between contacts trip and contacts reset
Overtravel — movement of the actuator beyond the contacts trip point
Initial Position — position of actuator when no external force is ap-plied to the actuator
Some other important terms associated with limit switches:
Operating force (torque) — force required to move the actuating element
Minimum return force (torque) — minimum force required to return actuator to its initial position
Total Travel — the maximum allowable distance the actuating ele-ment can travel
Repeat Accuracy — ability of a switch to repeat its characteristics precisely from one operation to the next operation
YBLX-ME/8000 series of travel switch is applicable to electric circuit with voltage not more than AC Ue 380V/50- 60Hz or DC Ue 220V and current not more than AC Ie 0.8A or DC Ie 0.16A as travel control, direction of motion or speed change of movement mechanism, automatic control of machine tool, limit action & travel or procedure control of movement mechanism.
