M8 E2B, Omron Proximity Sensor

Overview

The new E2B proximity sensors 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.

Features

• Perfect fit for standard environments
• 372 models
• Single and double sensing distances (M8, M12, M18, and M30)
• Time and cost-saving
• Global deliveries and support

Note:

1. The response frequency is an average value. Measurement conditions are as follows: standard sensing object, a distance of twice the standard sensing object between sensing objects, and a setting distance of half the sensing distance.
2. When using any model of M8 size at an ambient temperature between -25ºC and 60ºC, use a load current of 200mA max., at an ambient temperature between 60ºC and 70ºC, use a load current of 100 mA max.
