The Pilz 523120, also identified as PSEN 2.2p-20 /8mm 1 switch, is a magnetic safety switch designed for monitoring movable guards and access points on industrial machinery. Its compact round M30 housing supports flush mounting and provides an 8 mm operating distance when paired with the compatible PSEN 2.2-20 actuator.
Featuring one normally open and one normally closed contact, the sensor operates at 24 V DC and connects through a 4-pin M8 male connector. The durable PBT housing carries an IP67 protection rating, making it suitable for demanding industrial environments. It supports series connection, has a low coding level in accordance with ISO 14119, and operates across an ambient temperature range of -25°C to 70°C. The actuator and connection cable are supplied separately.

What type of device is this?
This is a magnetic safety switch designed to monitor the position of movable guards, doors and access panels on industrial machinery.
How does the switch detect a guard position?
It uses a magnetic sensing principle. When the matching actuator enters or leaves the specified sensing range, the switch contacts change state so that the connected control system can identify the guard position.
What contacts does the switch provide?
The switch provides one normally open contact and one normally closed contact, allowing complementary status signals to be monitored.
Which electrical connection is fitted?
Pilz 523120 has a four-pin M8 male connector. A compatible M8 connection cable is required for integration into the machine wiring.
What is the specified operating distance?
The specified operating distance is 8 mm when the switch is installed with the appropriate actuator and in accordance with the installation requirements.
Is the actuator included with the sensor?
No. This item is supplied as one sensor without an actuator. The specified matching actuator is the PSEN 2.2-20.
What are the housing dimensions and format?
The sensor has a round M30 housing design with a depth of 36 mm, making it suitable for compact machine-guard installations.
Can the sensor be flush-mounted?
Yes, the sensor can be flush-mounted, provided the required mounting positions, clearances and installation guidance are followed.
What environmental protection does the housing provide?
The housing is rated IP67, providing protection against dust ingress and temporary immersion in water when correctly installed and connected.
What is the permitted ambient temperature range?
The specified ambient operating temperature range is -25°C to 70°C.
What voltage does the switch use?
The switch is designed for 24 V DC operation, with a specified switching voltage of 24 V.
Can several switches be connected in series?
Yes, this model is suitable for series connection. The complete circuit must be configured in accordance with the relevant control-system and installation requirements.
Which interface can be used with this sensor?
The sensor is intended for applications using the PSEN i1 interface. The interface can accommodate up to four compatible PSEN sensors.
Which connection cables are compatible?
Compatible options include straight and angled M8 connector cables in lengths such as 2 m, 5 m, 10 m and 30 m. Cable selection should reflect the required routing and installation space.
What material is used for the upper housing?
The upper section of the housing is made from PBT, an engineering thermoplastic commonly used for durable industrial sensor enclosures.
Which standards and approvals apply?
The device carries approvals including CE, UKCA, cULus Listed, EAC and TÜV. It is classified as PDDB under EN 60947-5-3 and has a low coding level under ISO 14119.
