    Product Overview
    The E-MSM2 series safety door locks are the most commonly used door interlock technology. They use a key installed at the switch opening to detect the movement of the safety door. With their compact and lightweight design, diverse contact configurations, and locking function, safety door locks are usually the most cost-effective solution. In addition, the use of flexible keys increases their misalignment tolerance, making them suitable for a wide range of applications. The E-MSM2 series safety door locks allow the switch head to be rotated four times at 90° angles, the key can be inserted into the switch in seven different positions, and the solenoid can be set to operate with power on or power off. This provides a variety of options for the switch’s operating modes and installation methods on protective doors. This increases the flexibility of the switch, making it suitable for use on various types of doors.
    ◆ Built-in multiple contact structure options;
    ◆ Locking force of 1300N;
    ◆ IP67 protection rating;
    ◆ Housing made of PA66 flame-retardant material;
    ◆ Suitable for general or micro loads.

    ■ Locking method description
    Mechanical locking / electromagnetic releaseAfter the operating key is inserted, the contacts of the safety control circuit close (normally closed contacts), and the operating key is automatically locked by the mechanical locking mechanism and cannot be removed.
    After the internal electromagnet is powered, the mechanical locking mechanism is released, allowing the operation key to be removed normally. Once the operation key is removed, the contacts of the safety control circuit open.
    Electromagnetic Locking / Mechanical ReleaseAfter the operation key is inserted, it can still be removed normally at this time. Only when the internal electromagnet is powered will the operation key be locked and cannot be removed, and the contacts of the safety control circuit will close (normally closed contacts).
    When the internal electromagnet is powered off, the electromagnetic locking mechanism is released, and the operating key can be removed.
    Even when the internal electromagnet is powered on, the lock can be released by turning the mechanical lock knob from the LOCK position to the UNLOCK position using a release tool. At this point, the operating key can also be removed normally. After the operating key is removed, the contacts of the safety control circuit are disconnected.

    Wiring method

    · Do not wire the switch while it is powered on. Otherwise, electric shock may occur.
    · When wiring, do not allow small wires or other fine particles to enter the switch body.
    · When connecting terminals using an insulating tube or M3.0 crimp terminals, make sure they are not pressed against the housing or cover.
    · Applicable wire size: AWG20 to AWG18 (0.5 to 0.75 mm). Use wires of appropriate length for wiring. Otherwise, the cover may bulge or may not be properly secured.
    · Do not insert crimp terminals into the gaps of the housing, as this may cause damage or deformation of the housing.
    · To prevent the terminal from contacting the inside of the switch housing, use terminals with a thickness of less than 0.5 mm.

    Do not perform manual unlocking while powered on.
    Do not keep the coil energized for a long time when the door is open or in the unlocked position.
    Note: When there is a power outage or the electromagnetic coil is de-energized, inserting the operation key will not lock the door. Therefore, the door can be opened for operation. When locked by the energized solenoid coil, the door will not be locked in the event of an emergency or sudden power outage. Therefore, this model is not suitable for situations where hazardous conditions may still exist inside the equipment.

    ■ Installation method for the stopper base
    During installation, please be careful not to drop the product from a height. Otherwise, it may cause personal injury.
    Do not use the main unit as a stopper. Be sure to install the stopper as shown in the diagram to prevent the flange of the operating key from hitting the head.
