Mechan Controls - HED-21-DC-LQD-R, Coded Quick Disconnect Magnetic Safety Switch and 2 Actuator, 2NO/1NC, DC, Plastic, 8-PIN M12 Exit from Right

Mechan Controls safety switches of HE series are magnetically coded, solid state non-contact making them easy to install and tolerant to misalignment brilliant for use in machine guarding applications. Solid state makes them more tolerant to shock and vibration and provides single point switching which makes reliable, simple machine guard interlock. HE safety switches are able to connect to the SCU-1 Safety Control Unit making it possible to have up to 30 switches.

Operation

The HED safety switch monitors 2 adjacent doors with only one switch, saving on installation time, cabling and cost. With 2 x N/O + 1 N/C bidirectional solid state outputs along with a built in LED(s) for indication. When installed on a machine guard, power is applied, and the switch and actuator are within the specified operating range, the N/O Outputs will be closed, the N/C Output will be open.

How does Mechan describe the contact configuration? (IMPORTANT)

Mechan Controls describe the state of the safety contacts as N/O (normally open) and the auxiliary contact as N/C (normally closed) when the door is open and not within operating distance.

Volt Free Outputs

Volt free contacts are invariable mechanical contacts. In order to form a safety circuit, connection to monitored safety inputs is required.

Tolerant to Temperatures

Standard -25°C to 55°C.
