Subminiature Coaxial Switch 0.85mm High, DC to 11GHz
MS-180 Series

Oct.1.2024 Copyright 2024 HIROSE ELECTRIC CO., LTD. All Rights Reserved.

■Overview■Features

MS-180 series is the subminiature coaxial
connectors with switch, developed for inspecting theRF module functionality and high frequency circuits.
It can be used to mount on high density board ofminiaturized devices and multiband frequency. It
supports high frequency bands up to 11GHz.
Enable secure and easy inspection of circuits.
Verification of the circuit performance isaccomplished by simply inserting the external plugin the board mounted receptacle. This action
re-directs the circuit from normal condition to theplug side. Removing the plug restores circuit to its
normal condition.
Plug side is smaller than the previous model andoccupies less space in customer’s design.

1. Performs over a wide frequency range
Applicable frequencies range over a wide
bandwidth, from DC to 11GHz.

2. Low insertion loss

Space saving design
0.85mm above the board
1.8×1.8mm on the board

0.1 dB Max. up to 3GHz (not mated with the probe).
0.2 dB Max. up to 6GHz (not mated with the probe).
0.3 dB Max. up to 11GHz (not mated with the probe).

3. Space-saving and low profile design
0.85mm high above the board.
1.8mm x 1.8mm board space occupation.

4. Minimized Keep Out area and inspection
port on chassis
Thanks to thinner probing tip in 2.24mm outer
diameter, customer are able to achieve better spacesaving design.

5. Automatic board placement●PCB occupation

BPrecautions
1. Do not use the washing process.
2. This product is intended to be used for circuit inspection only. Consult us if any other application is considered.
3. Do not use lab use probe for mass production line.
4. Do not use hand soldering for mounting of MS-180, since it could result in solder and flux wicking to thecontact areas.
5. When using a heat gun, hot plate, or similar methods for mounting receptacle on PCB, limit the temperature to260°C apply for 10 seconds max.
6. Do not reflow the product other than using specified PCB footprint and metal stencil dimensions.
Otherwise it may cause solder and/or flux wicking affecting the product performance.
7. Avoid using the product in dusty, mixed gases and any other environment which is outside of the specified
range in spec sheet.
8. Do not allow any particles to enter the board mounted receptacle when cutting PCB.
