3SE6627-3CA01

What type of device is this?

It is a Siemens SIRIUS 3SE66 magnetically operated switch contact block designed to monitor the position of a right-hinged machine door or guard.

How does the switch detect the position of a door?

The switch responds to a compatible magnetic actuator. When the actuator moves into or out of the specified sensing range, the contact states change so that the connected evaluation unit can identify the door position.

Which magnetic actuators are compatible with this switch?

The matching actuator is Siemens 3SE6714-3CA for standard alignment. Siemens 3SE6724-3CA can be used when the actuator must be positioned at a 90-degree offset.

Is this version intended for a left-hinged or right-hinged door?

Siemens 3SE6627-3CA01 is configured for a right-hinged door. The hinge orientation should be checked before selecting or installing the switch.

What contact arrangement does the switch provide?

It provides two normally closed contacts for the main monitoring function and one additional normally closed signalling contact, identified as terminals 31-32.

What electrical connection does the device use?

The switch has an 8 mm latching connection with a six-pole plug. A compatible connector and cable assembly should be selected for the installation.

Does the switch have an integrated LED indicator?

No. This model is supplied without an LED indicator, so its switching state must be monitored through the connected control or evaluation equipment.

Is a separate evaluation unit required?

Yes. The switch is designed to operate with a suitable evaluation unit that monitors its contacts and provides the required machine-control response.

What are the rated electrical values?

The device is rated for 30 V DC, an operational current of 400 mA and an operating power of 10 W. The connected circuit must remain within the published electrical ratings.

What are the assured operating distances?

The assured switch-on distance is 5 mm, while the assured switch-off distance is 15 mm. Correct actuator alignment is important for dependable operation within these limits.

What is the maximum switching frequency?

The specified switching frequency is 5 Hz, making the device suitable for machine-door and guard-position monitoring rather than high-speed counting applications.

What level of ingress protection does the enclosure provide?

The enclosure is rated IP67, providing protection against dust ingress and temporary immersion under the conditions defined by the relevant IP standard.

What operating temperature range is specified?

The specified ambient operating temperature range is -25°C to +70°C.

What are the sensor dimensions?

The rectangular sensor measures approximately 36 mm high, 26 mm wide and 13 mm long, with a weight of approximately 0.029 kg.

What material is used for the enclosure?

The enclosure and active sensor area are made from glass-fibre-reinforced thermoplastic, providing a compact and robust housing for industrial environments.

How is the switch mounted?

The unit is installed using screw fixing. Its compact rectangular format allows it to be fitted almost flush, subject to the specified mounting arrangement and actuator alignment.

Does the device support cross-circuit detection?

Yes. The switch is designed to support cross-circuit and short-circuit recognition when used with compatible evaluation equipment and correctly wired monitoring channels.

What functional ratings are specified for the device?

When incorporated into an appropriately designed and validated control system, the device is specified for applications up to Performance Level e under EN ISO 13849-1 and SIL 3 under IEC 61508.
