A micro-proximity switch can be used as a non-contact position sensor in small spaces. The R12575 measures just 0.379-in long and 0.098-in dia., and comes from Standex Electronics in Cincinnati. Typical applications include industrial controls where the equipment design leaves little space for the proximity sensor.
The sensor is well suited for applications where the magnetic field is low and where space limitations are a design factor. There is no power draw in the off state, an important consideration for battery driven applications. Lead lengths and terminations can be customized.
Three standard sensitivity ranges are available. The series has typical operating time of 0.2 ms, and release time of 0.1 ms. It has a power rating of 3 VA maximum and will switch 0.1 Adc (Max) with a carry current rating of 0.5 Adc. Switching voltage is 50 Vdc (Max.). The series has an operating range of -40°C to +125°C.
