3SE6617-3CA04

What type of device is this?

This item is a magnetically operated switch from the Siemens SIRIUS 3SE66 range. It is a rectangular sensor unit designed for monitoring guard and access door positions in industrial equipment.

What is this switch typically used for?

It is typically used to detect whether a machine door, guard or hinged access panel is open or closed. The design is intended for installations where a non-contact magnetic switching principle is preferred.

Is this model suitable for use in safety-related circuits?

Yes. This model is designed for use in safety-related circuits and includes two NC safety contacts plus one additional NC signalling contact.

How many contacts does the switch provide?

The switch provides three normally closed contacts in total: two safety contacts and one signalling contact. This makes it suitable for applications that need both monitoring and signalling functions.

Does this switch need a separate evaluation unit?

Yes. An evaluation unit is required for this switch. When specifying the system, it is important to allow for the sensor and the appropriate evaluation arrangement together.

Which actuator is intended to work with this switch?

The matching actuator is the Siemens solenoid 3SE6714-3CA. An offset-by-90° option, 3SE6724-3CA, is also referenced for compatible installation arrangements.

What is the switching principle of this device?

It uses a magnetic actuating element rather than direct mechanical contact. This can be useful where a compact, concealed or low-wear switching arrangement is needed around machine guards or access doors.

What are the dimensions of the housing?

The housing measures 26 mm wide, 36 mm high and 13 mm long. It is a compact rectangular design that can be installed almost flush.

What is the cable length and connection style?

This version is supplied with a fixed 3 m cable connection. The cable sheath material is PVC.

What electrical ratings should be considered?

The rated operating voltage is 75 V DC, the rated operating current is 400 mA, and the rated operating power is 10 W. These values should be checked against the intended circuit conditions before selection.

What are the switching distances?

The assured operating distance ON is 5 mm and the assured operating distance OFF is 15 mm. These values help define the alignment and separation needed between the switch and its matching actuator.

What ingress protection rating does it have?

The unit is rated IP67, which means it is designed to offer a high level of protection against dust ingress and temporary immersion in water under defined conditions.

What temperature range can it operate in?

The stated operating ambient temperature range is -25 °C to +70 °C, making it suitable for a wide range of industrial environments.

How is the switch mounted?

It is designed for screw fixing. The sensor housing is made from glass-fibre reinforced thermoplastic, which supports a robust mounting arrangement.

Is this version intended for a particular door hinge arrangement?

Yes. This version is specified for a left-hand door hinge arrangement. If door orientation matters in the application, that should be confirmed during selection.

Does the switch include LED indication?

No. This version is supplied without LED indication. If visual indication at the switch body is important, that should be considered when comparing alternatives.

How often can the switch operate?

The stated switching frequency is 5 Hz. For applications with repeated opening and closing, this gives a useful reference point for expected operating speed.

What makes this model a good choice for compact installations?

Its small rectangular body, near-flush mounting capability, fixed cable connection and magnetic sensing principle make it well suited to compact guard door arrangements where space is limited. In applications needing these characteristics, Siemens 3SE6617-3CA04 is often a practical option.
