Operating principle (Reed switch)

The reed switch inside the coded magnetic switch turns ON (NO contact) or OFF (NC contact) when the magnet of the actuator comes close to the coded magnetic switch. The switch cannot be defeated with a commercial magnet or a metal piece because multiple magnets are used.

Compact

Easy positioning
Coded magnetic switches are ideal for mounting on protective doors that are difficult to position as there is space allowance to position with the actuator. Safety category 4 (EN/ISO13849-1) compliant
By using the HS7A coded magnetic switch with HR6S safety module, up to safety category 4 (EN/ISO13849-1) can be acheived. IP67
Because the reed switch is filled with plastic, the switches have strong dust and waterproof characteristics and can be washed with water. Requirements for using the coded magnetic switches correctly
Coded magnetic switches do not have a direct opening function where a circuit is always shut off when the guard is opened. Therefore, a coded magnetic switch must be used in combination with an exlusive safety relay module. HS7A Coded Magnetic Switches
Compact size and easy positioning.
Combination with proprietary relay modules achieves safety category 4 (EN ISO 13849-1). HS7A Coded Magnetic Switches

Safety Precautions

• In order to avoid electric shock or fire, turn power off before installation, removal, wire connection, maintenance, or inspection of the coded magnetic switch.
• Do not install the actuator in the location where the human body may come in contact. Otherwise injury may occur.

Instructions

• Safety category 4 (EN ISO 13849-1) can be achieved by combining the HS7A coded magnetic switch and HR6S safety relay module (monitor the dual contacts using the safety relay module).

• When using coded magnetic switches, combine with a proprietary safety relay module and confirm that the conformable safety category and the safety category (EN ISO 13849-1) required to the machinery have been achieved.

• Be sure to use the HS7A coded magnetic switch in combina tion with the proprietary actuator HS9Z-ZC1. Do not use other actuators.

• Do not install/remove the coded magnetic switch while the power is on.
  Coded magnetic switches have a built-in non-resettable short-circuit protection (fuse). By adding an external fuse (500mAgG) in series with each switch contact to avoid damage to the internal protection in case of misuse.

• Regardless of door types, do not use the coded magnetic switch as a door stop. Install a mechanical door stop on the edge of the door to protect the switch against excessive force.

• A shock to the door exceeding 300 m/s2 (approx. 30G) may cause a failure to the switch.

• Do not store the coded magnetic switches in a dusty, humid, organicgas atmosphere, or areas subject to direct sunlight.

cable near the coded magnetic switches. Precautions for Mounting the Actuator
Do not use the coded magnetic switch as a mechanical stop for movable guard.
Do not use a hammer to adjust a position of the coded magnetic switch.
Do not use the coded magnetic switch in a magnetic field of 0.3 mT or over. Operation Chart Contact Status Sao: Assured operating distance where the safety output is sure to turn on.
Sar: Assured release distance where the safety output is sure to turn off.
Note: When the transfer time between the actuator’s Sao-Sar is 500 ms or longer, the time lag is detected as an error.
