The HS7A series of non-contact interlock switches from IDEC can achieve category 3 or category 4 compliance when paired with the IDEC HR1S safety module. The HS7A series has the ability to connect up to 36 units together with category 3 been achieved when connecting two or more interlock switches to a single input. Alternatively, category 4 can be achieved by connecting a single non-contact interlock switch to a single input.
The HS7A series comes in two compact-sized bodies’s the DMC version measures only 21mm high, 16mm wide and just 7mm deep. The larger DMP measures 88mm high, 25mm wide and 12mm deep, this allows both variations of the HS7A series to be mounted in areas where standard interlocks simply would not fit.
Sealed to IP67 and with a mechanical life of 1.2 million operations the HS7A series is perfect for monitoring protective doors and guards where space is at a premium, but safety cannot be compromised.
