Series Overview
Series Overview
- ABB provides a complete series of Φ22MM button and indicator devices, including indicator lights, buttons, emergency stop buttons, selector switches, toggle switches, operating rods, buzzers, potentiometers, etc.; and also provides button boxes and a full range of accessories.
Compact Product Series
- Compact products include buttons with/without lights, selector switches without lights, emergency stop buttons, etc.
- Single integral unit, easy to select and use (one function corresponds to one order number)
- The front of the product has a protection class of IP67, and the rear has a protection class of IP20
- High - quality materials are selected, and all materials meet UL certification
- Can have up to two pairs of contacts at most (available contact combinations: 1NO, 1NC, 2NO, 2NC or 1NO + 1NC)
- Contacts are color - coded for easy wiring and enhanced safety (NO is green, NC is red)
- The contact block has a self - cleaning function. The contacts can still maintain good conduction after long - term use and have reliable performance even at low currents.
Modular Product Series
- Modular products include buttons with/without lights, selector switches, emergency stop buttons, double - head buttons, toggle switches and other series of products
- Customers can combine different component part numbers according to their needs to meet the required functions
- Suitable for outdoor and indoor use, with a protection class of up to IP66
- A maximum of 5 contacts can be configured in a single layer, and a maximum of 6 contacts can be configured in a double layer
- The contacts have a self - cleaning function, which can enhance the reliability of conduction; the contact connecting rods have color coding for easy identification.
Standard Testing
- ABB emergency stop buttons are designed and tested according to the IEC 60947 - 5 - 5 standard. Mechanical locking is performed before the electrical function is activated to prevent misoperation. And through strict product testing, it meets various use conditions, ensuring reliable quality and personal safety.
Performance Testing
- 1. Operation Test
- 6050 operations
- Endurance test of the locking part
- 2. Strength Test
- M = 0.1×D \(_{hole}\) = 2.2 Nm
- F = 5×D \(_{hole}\) = 113N
- 3. Dry and Wet Test
- Verify function after 96 - hour test
- +70°C dry air
- Hot and humid air (+25°C/+55°C, 97%/93% RH)
- -40°C
- +35°C 5%NaCl solution
- 4. Impact Test
- According to standard: IEC 60068 - 2 - 27
- Test parameters:
- Impact force: 15g (equivalent to 150m/s²)
- Duration: 11ms
- During the test, closed contacts cannot open, opened contacts cannot close, and the locking mechanism cannot lock/unlock
- 5. Vibration Test
- Frequency: 10 - 100Hz
- Time: 2 hours
- Acceleration: 50m/s²
- Amplitude: 0.35mm
- 6. Locking and Opening Test
- The actuator of the emergency stop switch should move slowly until the locking point, and the normally closed contact should open here.
- Tested by a pulse voltage at 2500V.
- 7. Locking and Opening Test
- According to IEC 60947 - 5 - 5/7.7.3
- Simulate the action of a normal operator
- The emergency stop button is installed in front of a 1.6kg pendulum hammer
- After being impacted, the locking mechanism should be locked (h = 75mm)
- 8. Locking and Opening Test
- Reset pull force should be less than: 50N
- Torque should be less than 1Nm
- 9. Impact Test
- Use a 1.6kg hammer to strike 3 times, h = 310mm
- After each impact, the emergency stop button should be activated
- After three impacts, the emergency stop button should not be damaged
- 10. Function Test
- Types of use: AC - 15 and/or DG - 13 or DC - 14
- NC contact directly opens
Features
-
L - MARK Custom Marking Pattern, Easy and Simple ABB has developed a new system to facilitate customers to customize marking patterns on button and indicator devices. In addition to engraving characters on the nameplate, ABB can also provide products with laser - printed custom patterns on the button and indicator devices. On the L - MARK website, customers will receive an order number for products with custom marking patterns. This code can be saved, making re - ordering easier and ensuring customers get the perfect customized product.
-
Contact Self - cleaning Function Whether for compact or modular products, the contact blocks have a wiping action to achieve the contact self - cleaning function. During operation, the moving contact rolls and then slides to the side after contacting the static contact. Due to this feature, the contact self - cleaning function can be ensured even in low - current applications.
-
Fast and Convenient Installation The installation of all ABB button and indicator devices is very convenient and flexible. Elastic installation can ensure the accurate position of the operating head and the nameplate. The operating head of ABB can be used in both concave holes and round holes. The product adopts a modular card - loading design and is one of the fastest - assembling products on the market.
