***MA SERIES Simple Wire Protector Printed Circuit Terminal Blocks ***
The printed circuit terminal blocks MA series fulfill all basic quality features:
MA series terminal blocks have between 2 and 24 positions with a 3.50 mm, 5.00 mm, 7.50 mm or 10.00 mm pitch. Moreover, MA series Wire-protection clamps provide the highly precise dimension, cost-effective, fit-for-purpose and compact wring solutions. The simple clamping mechanism reduces the product cost.
The 2&3 pole modular designed terminal blocks can be quickly and easily joined together to produce higher pole number assemblies, however, it depends on the actual situation, for mass quantity, we ca supply the One-piece housing product.
MA series allow screw connections for conductors up to 1.5 mm2 to be realized without soldering.

Ma series are using brass or copper alloy as the fixture for wire connection, which ca make the product be free maintenance, anti-vibration, preventing from screw loosing, outstanding corrosion resistance, and high reliability.

When the clamping screw is turned, it pushes the Leaf Spring onto the conductor until a secure connection is achieved. The Leaf Spring prevents the screw from the digging into the conductor and damaging individual conductor stands.
MA series products acquired the approvals of UL, CE, and VDE. MA series ensuring compliance with rigorous quality standards. Our customers also appreciate our dependability, punctual deliveries and outstanding value for money.
A wide selection of accessories rounds off MA series product range.
If desired, MA series terminal blocks can also be supplied with individual printing and marking.

SPIROL Industries manufactures all standard inserts from brass. In the majority of situations brass will exceed the performance requirements of the application while providing the lowest installed cost solution.

The thermal characteristic of brass enables the inserts to heat up and cool down quickly during the installation process into moulded plastic parts. For those inserts that are installed with heat or ultrasonics, the fact that the brass insert heats up quickly translates into faster installation time.

From a quality perspective, the fact that brass cools quickly means that immediately after the heat is removed from the insert the plastic will start to coagulate which will secure the insert in position and prevent it from “floating” within the hole.

When it comes to machining, brass is much easier to cut than most ferrous materials. Whereas brass and stainless steel generally cost about the same per pound as a raw material, it’s the significant increase in manufacturing time for stainless steel that drives up costs.

Though brass is an excellent choice for most components, there are instances where stainless steel may be required. For example, brass and stainless steel are both corrosion resistant, yet each will react differently to various corrosive agents. Brass is an excellent material for use in most industrial and agricultural applications and typically offers the lowest cost solution. It offers much better thermal conductivity than carbon or austenitic stainless steel and is much more efficient material to machine than stainless steel.

Many varieties of stainless steel are available, although 300 series, or austenitic stainless steel, is most comparable to brass in terms of those insert applications where stainless is commonly used. It is critical to understand that the properties of stainless steel vary dramatically from one alloy or family to the next. It is critical to understand that the properties of stainless steel vary dramatically from one alloy or family to the next.

Stainless steel is more difficult to machine than brass and cycle times are much longer which increases cost significantly. Tool life is also severely limited which further increases cost. Austenitic stainless steel provides higher service temperatures than brass. However, it is important to note that the service temperature of the assembly is usually limited by the heat deflection temperature of the plastic host.

During the production of safety relevant fixture parts, for instance, for automotive seat frames, one must ensure that all assembled parts also hardened. The same applies to products, which are exposed to extended wear and tear in order to avoid early failures. In this application the customer wanted to test sheet metal parts of the approximate size of 70 x 80 mm up to 75 x 150 mm. As the parts are assembled in an automatic production line these tests must be done automatically in order to identify parts which not hardened or have other defects in order to eliminate them from the process.

The very cost-effective Eddy Current Comparator I 20 consisting of two sensors facing each mounted in a C-frame and connected to the control unit. The sensor principle is the so-called transmission principle. The transmitter generates an electromagnetic field which is dampened by the test sample in the sensor gap. The voltage measured at the receiver corresponds to the magnetic and the electrical properties of the parts being tested. Because the hardened parts differ from parts which are not hardened by the magnetic and electric properties: the system has a high discrimination capability. The control unit will detect this difference and issues an output signal in order to discharge the defective part from the process.

Advantages of this ROLAND solution:
- Cost efficient
- Simple sensor mounting
- Easy teach-in
- Very fast detection
