Radiation Tolerant and High Temperature Resistance 175°C
This Proximity Switch is constructed using 316L Stainless Steel billet machined housing components and benefits from the Field Wireable Connection Head - 360° Rotatable housing with SPCO / SPDT (Form C) , volt free Palladium-Silver contacts.
It has a wide operating voltage from 6V DC to 240V AC and minimum reliable switching load from 10mA up to a maximum switching current of 4A.. These switches are able to sense ferrous material, such as carbon steel or stainless steel (17/4 or 400 series), through the end face at up to 2.5mm|0.10" and are reliable through millions of operations.
The Wireable connection head is supplied with PEEK terminals for connection of customer cable in plant. The unit is a compact and lightweight design and is IP 66/67/68 rated.
No mechanical lever arm torque, or adjustment required throughout lifetime. Radiation aged to 527kGy and is suitable for mild-harsh radiation zones.
