MS-156C Series/1.35mm Height, Coaxial Switch for Ultra Small Size Inspection

Overview
MS- 156C series is ultra small coaxial switch developed for inspection of microwave circuits used for portable terminals
circuits and high frequency circuits.
It supports high- density substrate mounting by small size equipment, and supports over a wide frequency range up to11GHz. Also, you can easily perform circuit tests while in small size.
In the unplugged state, common contact and antenna contact are connected to form circuit.
By mating the plug, the antenna contact switches to the plug side circuit.
Some conventional MS- 156HF plugs can be used for the plug connector.

Precautions
1. Do not mounting this product using PCB patterns or metal mask dimensions other than the ones specified. It may resultin a product malfunction due to solder and/ or flux wicking.
2. Cross- hatched area
shown on the PCB mounting pattern must be free of any conducive traces.
Placing conductive traces in this area may affect performance and will void product warranties.
3. Do not use hand soldering for mounting of MS- 156C3.
Doing so could result in solder and flux wicking to the contact areas.

4. If the substrate after MS- 156C3 mounting is to be cut off by a router, etc. , the web tab should be designed away fromMS- 156C3 because it may cause item dysfunction due to grinding powder.
Also, make sure to suck out the scraping powder so that it does not scatter during the process.

Web Tab

MS-156C3

MS-156C3

If there is a web tab near MS-156C3, it may cause switch dysfunction due togrinding powder getting into the inside of item during separation.

Optimal design with no web tab near
the MS-156C3.

5. This product is intended for use only in testing the circuit. It cannot be used as an interface.
6. Do not use the product in special environments such as dust, high humidity, gas, very high temperature or very lowtemperature.
7. Plugs can be roughly classified to two types.
- For mass production line automatic check ( Press down type)- For manual check ( With retentive lock) : Unable to be used at production line.
8. Do not use the washing process.
9. Please use a design in which the device housing does not exert pressure or force on the MS- 156C in the eventthat the finished device is accidentally dropped.
10. Do not apply heat ( heat gun or hot plate) over 260℃ for more than 10 seconds.
Exceeding this thermal limit could cause the resin to melt and cause deformation.
11. When automatic inspections are to be performed during the manufacturing operations, request the MS- 156 plugconnector manual for examples of implementation.
