Safe condition detection

elobau offers a wide portfolio of products for safe condition detection. Magnetically actuated safety sensors allow concealed installation with high operating distances and offset values. Additionally, the risk of manipulation is significantly limited. For small machines, a space-saving safety sensor with integrated evaluation electronics is available. The safety interlocks prevent guard doors from opening and machines restarting while the guard doors are open. The machine safety product range is complemented with emergency stop buttons.


Safe condition detection for potentially explosive gas and dust environments

In its extensive product line, elobau offers solutions for applications in potentially explosive gas and dust atmospheres. The proximity switches are designed in accordance with the corresponding standards and directives making them suitable for use in the chemical and pharmaceutical industry and in oil- and gas-processing systems, such as painting lines.

All sensors are approved in accordance with the ATEX directive 2014/34/EU, certificate number BVS 03 ATEX E 126 X

Safety sensors with approval in accordance with ATEX guideline 2014/34/EU

Safe signal evaluation

The safety relays have been designed for reliable safety performance. They are an ideal safety solution for various applications. All signals from safety sensors, emergency stop buttons and safety interlocks are safely monitored and comply with the machinery directive 2006/42/EC.

Accessories for machine safety

For optimum performance in terms of operating distances, offset values and tampering protection, the actuators should be used with the corresponding safety sensor.

When selecting the correct combination of safety sensor and actuator, care should be taken to ensure the maximum opening gap of the machine is not exceeded.
