TEKMEC make series TLS Limit Switches are being manufactured as per rigid quality standards conforming to IS/IEC 60947 (Pt. 5 / Sec. 1). These Limit Switches performs in most contaminated atmosphere.
Long Electrical / Mechanical Life.
Protection against oil, dust and other industrial conditions.
Limit Switches enclosure has been designed for service under most aggressive conditions. A rubber diaphragm with a sealing ring under the push rod guide provides protection against any leakage from this direction. A ridge on the housing along with oil resistant rubber gasket under the cover prevents oil and water seepage. External mounting holes further ensure oil tightness. The enclosure complies with IP65 protection requirement.
An ingenious design of the limit switch head permits rotation in steps of 90° thus enabling use of the actuating rod from any of the four directions Limit Switch are available with straight as well as angular roller levers. Straight lever is used with horizontal actuator while angular lever for vertical actuator.
Terminals are suitable for straight end connections for two wires of equal or different sizes.
Close tolerances for push rod guide and contract bridge lead to very high level of accuracy. Position of contacts for the Limit Switches maintained within very fine tolerances even after a large number of operations.
For optimum utilisation of TEKMEC L imit Switches, appropriate application is very important.
Applied force should not be excessive.
Roller Lever should not be in opposition to the actuating movement.
Push Rod speeds upto 1M/sec are permitted in the direction of stroke.
Speed of moving contacts should not be less than 0.015 M/sec for DC
For lower operating speeds, use snap action switches.
Avoid installing Limit Switches in locations subject to heavy vibrations.
Actuator angle can be upto 45° with roller lever with actuation in the direction of roller level.
