P25SMT103
Overview
The P25SMT103 is a low-profile hexadecimal coded rotary switch designed for surface mount applications. It provides a compact 7x7mm footprint with 16 distinct positions, outputting a standard hexadecimal code across its gull-wing leads. This switch features a flush, recessed actuator intended for tool-based adjustment, preventing accidental changes in the field.
Why Choose This Part
This switch offers a high-temperature rating up to 125 degrees Celsius and a robust gold contact finish for reliable low-current switching at 100mA. Its extremely low profile of 2.5mm makes it ideal for height-constrained enclosures, while the surface mount gull-wing design simplifies automated PCB assembly.
Applications
Key Specifications
Getting Started
To integrate the P25SMT103, design the PCB footprint for a 7x7mm SMT component with 6 pins as specified in the Apem P25 series datasheet. The hexadecimal output requires 4 digital input pins on a microcontroller, typically configured with internal or external pull-up resistors to decode the 4-bit binary-weighted signal.
