Relays
 The Best In Relay Technology - Our Complete Program
Since INCOTEL ELECTRONICS has been the Dealer for HENGSTLER Products in the Middle East in 1999, we have been able to offer you the widest possible product range to meet all needs. We've got relays from 1a to 100a, in various designs and with the right contact material to meet all loading requirements.
The use of relays is sharply on the increase as they provide a powerful, flexible and economical interface between electronics and load. If you have any questions about which is the right product for you, our specialists are available, in person or on the telephone, to give you all the help you need.

Our program includes

  • Safety relays with force guided contact sets
  • Powerful high voltage relays
  • Reliable mains separation relays
  • Compact high performance relays
  • Robust all-or-nothing relays
  • Printed circuit board relays

... and much more, including customised specials.

    
Our Particular Speciality - Safety Relays
You can't afford to make compromises when it comes to safety issues. Safety relays with force guided contact sets containing from 2 to 10 contacts give you the safety you are looking for as they can eliminate the risk of danger to man or machine, caused by switching or system failures. Their importance is becoming increasingly international.
 We make our safety relays as small as possible, but they are big on reliability and switching safety. They're big on variety too; big enough and flexible enough to meet all your needs.

The global importance of safety relays is growing rapidly and the worldwide market-place is a challenging place to be in. With Hengstler you have the widest range to choose from to meet your and your customers' needs.

Heavy-Duty, Bistable Relays
                  
                

These days, many control applications demand low power requirements which call for a high switching performance at many different load levels. These demands can be met by the bistable relays from HENGSTLER-KaCO.

Application examples:

  • Ripple control receivers
  • Pre-payment meters
Application examples:
  • 1 impulse switching
  • Current up to 100a
  • Excitation is retained after switch off, until the relay is switched back to active by a corresponding negative excitation
  • Impulse duration is 20 - 30 ms so the unit does not get warm through coil heat loss
  • The switching position is set by the direction of the excitation. This is achieved by using permanent magnets, i.e. poled bistable relays
  • The permanent magnets allow a high, constant contact strength in both switching positions, irrespective of the power supply
  • The high contact strength at closing and opening minimises contact resistance and power heat loss in the area of the contacts
  • Simplified control layout by the use of symmetrical relay control
  • Control can be made with a memory capacitor
  • Vibration and shock resistant
   
Safe Mains-Separation Relays

Mains separation relays are primarily used where devices require a bi-polar mains separation, for instance to conform to DIN VDE 0700; with a contact opening of 3 mm. Portable electronic testing devices must always be in a safe and stable state to be able to carry out the required tests, i.e. the load circuit must be separated from the mains.		 The same principle applies of course in medical technology, to protect the patient.


HENGSTLER-KaCO mains separation relays have been developed and optimised in co-operation with customers who are market leaders. You can also profit from the wealth of experience we have been able to draw on.

Application examples:
  • Domestic appliances
  • Medical and laboratory equipment
  • Measuring and test equipment
   
Compact High Voltage Relays
With high voltage relays you can switch up to 5,000 Veff, making them an interesting component for use in test equipment, e.g. test switching high voltage transformers or for testing conductors or insulation. Laboratories are also often places where high voltage switching tasks are carried out.

  • Measurement and test equipment
