Industrial light touch switch is widely used in various detection and control. Touch the switch to complete the presence / absence detection in the area that allows physical touch. When an object is detected, the switch actuator acts, and the normally open or normally closed electrical contacts in the switch body will change the state, and then complete the on-off of the communication / DC circuit.
When the equipment is put on the heavy construction machinery, agricultural equipment or solid waste treatment vehicle, the function of the light touch switch will be tested to the maximum extent. These uses can produce very strong shocks and oscillations. These machines and equipment generally work all the year round in a very strict outdoor and turbid environment, so they will be affected by various environmental factors. In these cases, it is very challenging to insist on the corresponding functions and functions effectively and efficiently with each action of tap switch. For light touch switch users, reliability, durability and safety are the three most critical elements.
Honeywell can provide rich micro switch products (including heavy load and medium load) to adapt to different industrial requirements. These heavy-duty mechanical and electrical products can not only provide higher functions for severe and harsh industrial use, but also provide more safe working environment for operators.
Considering the impact and oscillation produced by these machines, it is very likely to encounter the following situations when you touch the switch lightly:
Switch contact fault
The internal and external mechanical connection of the switch is damaged or loose
The abrasive powder produced by the internal parts of the switch can shorten the service life of the switch, and even cause related problems
The lighttouch switch has high flexibility in dealing with strong oscillation, impact and collision force. It can be directly installed on heavy machinery or close to each other (there are large force loads in these directions). These industrial light touch switches have a wide range of NEMA / IP protection levels and can provide maintenance against environmental factors such as rain, moisture, hail and liquid splashing. These heavy duty light touch switches are planned to operate in both low (extremely cold) and high temperatures.
Chuck and concave head planning, can adhere to the solid clamping from the head to the main body
The enhanced plug-in terminal planning is used between the switch body and the socket, and the electrical continuity can be maintained under the conditions of pole temperature, oscillation and impact
Self raised pressure plate terminal can save wiring time
The grounding terminal (internal) is easy to identify and meets the standards of relevant regulatory authorities
Each switch has four device holes: two through holes for front devices and two threaded holes for back devices
Dual shaft seal for rated maintenance (optional with fluorocarbon or fluorosilicone seals)
Common chip planning ensures proper torque
Use diaphragm seals as rated maintenance measures
The robust and corrosion resistant zinc head and body are phosphate treated and epoxy coated
303 stainless steel operating shaft on sintered brass bearing can achieve longer mechanical life and higher operation reliability
Domestic and international pipe threads
Use of heavy load light touch switch
The cement pump truck has a long articulated arm or rod, which can transport concrete to the position that is difficult or impossible for the general cement tank truck or pumping machinery to reach. The Honeywell HDLs touch switch is used to detect the orientation of the beam. When the beam is in place, a light touch of the switch sends a signal to the operator.
Heavy equipment and machinery in transportation, agriculture, solid waste treatment, construction or industry are affected by extreme operation and severe environmental conditions.
We place heavy and medium load light touch switches in rigorous oscillation and shock testing equipment and procedures, and the effects are very similar to those under real operating conditions. Oscillation and shock test conditions are very close to the actual environment.
Each part or structure of the touch switchnaturally has higher accuracy, measurability and durability to improve functional output and endurance. Honeywell's sensing and control solutions are also flexible and can be tailored to specific specifedications -xa for emple, providing greater functionality and longer service life to ruce costs and operating costs.
