  Electronic Switches (I) P. Ltd; offers Reed switch for Cylinder position sensing. Cylinder piston is to be fitted with a permanent magnet. The normally open contacts of the reed switch close when the piston comes near the switch.

Technical Information:-
1. Do not exceed rated specifications, permanent damage to the sensor may occur
2. For reed switch type sensors polarity must also be observed for the proper functioning of LED.
Connect brown wire in series with load positive (+) and blue wire to negative of power source. If
polarity is reversed, reed switch remains functional but LED will remain in OFF state.
4. An external protection circuit may be required if the reed switch is used with Inductive load such as
relay or solenoid. For DC Inductive load attach an external diode parallel to the load and use RC
circuit with AC inductive load
5. Keep Sensors away from the magnetic field to prevent malfunctions. When using Reed switch with
capacitive load or if the load wire length exceed10 mtr. An inductor must be installed in series with the
sensor to prevent damage ( Refer Fig.3 ).

Electronic Switches (India) Pvt. Ltd. offers Anti Crane Collision Switch for two over head cranes on the same rail. These units are installed on two cranes on the same rail approaching each other. With these units, the two cranes on the same rail will never collide with each other & thus the damage caused due to collision can be saved. The minimum distance in between two cranes will always be maintained, and the cranes will be able to move away from each other but not closer.

Unit has inbuilt Infra Red Transmitter & Receiver along with other processing circuit and power supply. It works on 110 VAC and 220 V AC supply and offers potential free relay contacts. These contacts are interlocked with the contactor for direction of motion towards each other. Set consists of a control unit and a reflector. Control unit is fixed on one Crane and the reflector on the other crane opposite to the control unit. Same way another control unit should be fixed on second crane and it's reflector on first crane, opposite to each other. Make sure that both the control unit should not be placed opposite to each other. Alignment of both the units is necessary, as the rays transmitted by the Transmitter will be reflected back by the Reflector. A Laser Alignment Tool is provided for perfect alignment of control unit and reflector.

The reflected beam will be picked up by the receiver when both the cranes come closer. When the two cranes come within the range, the moving crane will be stopped immediately. This range can be adjusted for single set point, as required. For two set points, one can be adjusted to get an alarm at required distance and another can be set to stop the crane at required distance.

Product :

Bulbs / Tube Lights / CFL are kept ON during the night to keep the surrounding area lighted.  It is essential as lighted area offers security and mental relief.  However in most places such lights are often kept ON  even after day break  and are switched OFF only when somebody notices them resulting in wastage of electricity and correspondingly higher costs. Now we offers a  3/4 wire Twilight Sensor, which is simple, versatile as well as cost and energy efficient solution to this problem.  Bulbs, CFL as well as Tube lights can be made ON automatically in the evening and can be put off in the morning or at midnight automatically.  It  switches the lights ON only when they are actually required.
>     Suitable for Homes, Houses, shops, offices, flats, small buildings.
>     When you go out of station, it offers security to your house.
>     Simple installation. User can use product on his/her own in no time.

Applications :

Model  TSW 103/4 :
This model is suitable when lights are required to be ON during whole night.  Here lamp will get ON in the evening when it is dark and will get OFF in the morning.  Any type of lamp such as bulb, CFL or tube light can be connected to this unit.

Model TSW 203/4  :
This model is suitable when lights are required to get ON in the evening and to go OFF automatically when we go to bed.  Here lamp will get ON in the evening when it is dark and will automatically get OFF approx after  4  hours.  Any type of lamp such as bulb, CFL or tube light can be controlled.

This is particularly very useful when everybody in the family goes out of station. Using this, few lights can be made ON in the evening and OFF after 4 hours. This offers security to the house as it gives impression as if somebody is attending the house.
