Contactless safety switches
Non-contact switches with safety function are ideal for applications where precise guidance of the shield is difficult. Non-contact switches with safety function offer the solution with moving safety devices such as doors, flaps, fences or protective covers. When opening a safety device, dangerous machines and machine movements must be stopped. Non-contact switches must prevent the machines from restarting and must not be manipulated or circumvented.
Versions of contactless switches:
- Electronic safety switches (unique frequency control)
- Magnetic safety switches
- Magnetically coded safety switches
- Coded RFID safety switches
Contactless switch - Unique coded RFID
The non-contact safety switches from ReeR Safety operate on the basis of Magnus RFID sensors. RFID sensors transmit uniquely encoded radio waves, making the system very reliable. The uniquely coded radio waves are difficult to imitate and ensure that the communication transfer of the safety sensors is not sabotage, something that is possible with magnetic sensors. Magnus RFID enables a safety level up to PLe / SIL3. Even when the contactless safety switches are connected in series. This system is safe and reliable thanks to the unique codings. Read more about contactless safety switch with Magnus RFID.
Three coding types:
- Unique coding: transmitter and received are permanently linked to each other.
- Individual coding: Once used and retouched, a coding can not be reused.
- Encrypted actuator: The receiver is free and not specifically assigned to a transmitter.
Coded magnetic safety switches Cat. 4, SIL 3 and PL e
The HE-Series from Mechan Controls is an encoded magnetic safety switch and is fully encapsulated with resin, which makes the switching sensor extra sturdy.
High safety level
The HE series has a safety level of Cat 4, SIL 3 and PL e and a correct operation at -30 ° C. The housing of the HE series safety switches is equipped with resin which makes the switches resistant to vibration, high pressure cleaning and most difficult environments. The magnetic switch is also available in stainless steel and suitable for use in the food processing and packaging industry. Read more about coded magnetic safety switches Mechan HE series.
Coded RFID safety switches with volt-free contacts - IP69K
The RSS series safety switches are unique because they use volt-free contacts. You are free in your choice of relay. The non-contact operation of the safety sensor makes the RSS series easy to assemble and install. The safety switches are individually coded and suitable for high security applications for securing machines. The RSS series safety switch is available with a IP69K sealing degree for use in humid and dusty environments. Read more about encrypted RFID safety switch RSS series.
Magnetic safety switches IP67 - Plastic and stainless steel
The magnetically operated safety switches from Mechan Magnasafe are fully encapsulated contactless switches. The safety switches are cast with resin which makes them extra strong and ideal for use in rough and / or wet environments for prolonged use. You can choose from a plastic or stainless steel housing. Thanks to the fully sealed IP67 seal, the safety switch is suitable for cleaning under high pressure. Read more about Magnasafe contactless safety switches.
Electronic safety switches with unique frequency control
Mechan Controls S-Type is an electronic safety switch that operates on the basis of Mechan's unique frequency control. The S-Type safety sensors are safe, standalone, contactless safety switches with status display. The precise operation and switching ensures a reliable safety system.
The electronic safety sensor can not be manipulated, has a switching distance of 10 mm, equipped with a status indicator and has a quick disconnect option. The S-Type safety switches are available in three sizes with a maximum of 2 NO safety contacts and 1 NC auxiliary contact. Read more about S-Type safety switch.
Safety switches EX zone 1 and 21 - Coded Hall Elements
The safety switch steute Ex HS SI 4 is suitable for extreme environments, EX zone 1 and 21. Thanks to the thermoplastic housing, the safety switch can be used in environments with temperatures of -20 ° C and + 60 ° C. The safety sensor uses the Hall effect for the measurement of a magnetic field or electrical current. The steute EX HS SI 4 safety switch has a switching distance of up to 7mm.
Non-contact switches - Cylindrical - ATEX
The safety switch steute Ex RC SI M30 has a cylindrical design with a brass or stainless steel housing with sealing degree IP67 and has a long lifetime (mechanical life: 10 million operations). The safety switch is magnetically coded with a switching distance of 6mm. The 'extreme' safety switch can be used in environments with temperatures of -20 ° C and + 70 ° C.
Safety switch for extreme environments - Contactless switch
For applications in environments with extreme temperatures, potentially explosive areas and hygiene-sensitive food production, standard switching devices encounter limits. The Extreme safety switch BZ 16 of steute has a degree of sealing of IP69K, suitable for cleaning with hot water (80 °C) at 100 bar pressure of 100 mm distance from different directions.
