Omron M30 E2B Proximity Sensor

Omron M30 E2B Proximity Sensor promise the perfect fit for your particular needs. With the wide range of models in the E2B family, you can choose the one that exactly meets your needs. For example, we have four different sizes: M8, M12, M18, and M30, each one with single or double sensing distances, shielded, and unshielded. There’s also a choice of short and long bodies, two connecting methods, and four output types. With this range to choose from, you’re certain to find the perfect fit.
