Ex-certified proximity switches for extreme ambient temperatures

The intrinsically safe ATEX- and IECEx-certified proximity switches from EGE’s IGEXHa and IGEXPa series are suitable for use at extreme temperatures. IGEXHa inductive sensors withstand ambient temperatures of up to +140°c.

IGEXPa “polar” models are suitable for down to -60°C. Both series are approved for operation in zones 0/20. They feature IP69 ingress protection and are available in M12, M18, and M30 designs. Given a flush installation, the nominal switching distances are 2mm, 5mm, and 10mm, depending on the design.

The proximity switches are connected via a 2m FEP cable. EGE supplies the sensors with different cable lengths on request. EGE also offers the IKMb 122 Ex series of suitable IECEx-certified signal processing units and intrinsically safe power supplies with programmable outputs. Internationally active machine builder’s benefit from the IECEx certification since it facilitates exporting products that integrate these proximity switches.
