With the help of this slide show one can understand what are spring loaded pins.

1. SPRING LOADED PINS

2. WHAT ARE SPRING LOADED PINS?
• Spring-Loaded pins, sometimes called Spring-Loaded Contacts, or
Pogo Pins, provide a highly-reliable, precision made interconnect
solution ideal for several demanding application requirements in the
fast-moving world of electronic interconnects.
• It is available to make connections between Battery to PCB, Antenna
to PCB and Board to Board on a small space.
• A Spring-Loaded Pins consists of pin body, plunger and spring.

• A combination of Spring Loaded pins with insulator allows for
production of custom products that can fit various shapes and sizes.

3. WHY SPRING-LOADED PINS?
• Spring contact probes provide a constant force against the mating
contact surface, easily absorbing and compensating for movement
seen during shock and vibration without contact interruption.
• Spring contact probes provide repeatable contact in the field for
modular components, reduce costs, and eliminate cabled connections
by providing a dependable direct connection in rotating or sliding
joints.
• Spring-Loaded Pins provide a reliable electrical connection in the most
rigorous environments.
• This inherent design characteristic makes spring loaded pins ideal for
bayonet and sliding mate connector designs.

4. ADVANTAGES:
• Provide constant force against the mating contact surface
• Reduce cost and eliminate cabled connections
• Provide a reliable electrical connection in the most rigorous
environments.
• Ideal for blind mating applications
• Ideal for creating solderless interconnections between mating
modules

5. APPLICATIONS:
• Data Collection Terminals: It can be used between key pad and
Antenna.
• AV Equipment’s: Battery Connectors, Signal and Power
connections for lenses.
• Wireless Communication: In Charger units and cradle and
Handset of Walkie Talkies.
• Aero Space: In input output units.
• Health Care: As charges and as board to board connectors.
• Automotive: As charges, in rear display monitor, in car mirror
adjustment, in brake sensors module and its signals.
