Maxim MAXREFDES88 Proximity Sensor
Reference Design

Maxim MAXREFDES88 Proximity Sensor Reference Design is one of the world's smallest industrial proximity sensors featuring a complete binary magnetic proximity sensor. The solution features one RedRock™ RR100 micro-electro-mechanical systems (MEMS)-based magnetic reed sensor and the MAX14838, an industrial sensor output driver. The device may be configured to PNP or NPN outputs and be configured as normally open or normally closed without any changes to the bill of material. LEDs indicate sensor open or closed and error detection. The sensor operates at the conventional industrial 24V, but also across a range of 7V to 34V. An integrated LDO provides 5V to other portions of the system. The entire system consumes roughly 30mW of power. This tiny sensor fits into just about any location and drastically extends your ability to sense in a control and automation application.
