Minotaur™ Safety Relays

Minotaur™ Safety Relays are single channel and dual channel units with a variety of available options. Models are available with automatic, manual or monitored manual resets to operate at 24V DC, 120V AC or 230V AC. Number of outputs ranges from 3 to 9. Outputs with timed delays, two-hand versions and expansion units for up to 8 additional outputs are also available.

CU1 Electronic Timer Relay

The CU1 is a compact timing unit, designed to energize and thus unlock guard locking devices. It has been developed to integrate with the Guardmaster Atlas, Spartan, or TLS-GD2, on machines which have a run down cycle or do not stop immediately. It may also be incorporated into other parts of the safety related controls system, should a predictable, on-delay be required.

Features: Timed delay output 0.1s to 40 min, 2 N.O. safety outputs, 1 N.C. auxiliary output.

Ferrogard Magnetically Actuated

The Ferrogard range of magnetically actuated safety switches offers non-contact reliability together with tolerance to misalignment. They are designed to be installed so that when a guard door is opened, the action of the magnetic actuator being removed from the switch opens the N.C. safety contacts which are intended for the isolation of control power to a machine primary control element.

The FRS1, FRS2, FRS20 and FRS21 are rectangular housings. Sealed to IP67 (NEMA 6P), these Ferrogards are ideal for wet environments.
The GD2, GS1 and GS2 are housed in stainless steel or brass enclosures for heavy duty applications. The GS2 housing is an Ex-style for hazardous locations.

Features

- Non-contact actuation
- High tolerance to misalignment
- High switching current
- Plastic, brass or stainless steel housings
- Cable, quick disconnect or terminal connection options

Trojan 5 Universal

The Trojan 5 is a universal tongue (or key) actuated safety interlock switch designed to fit at the leading edge of sliding, hinged or lift-off guards. The dual key entry slots and rotatable head, movable only by releasing the cover screws, allow four actuator entry options. The Trojan 5 contains all of the safety related functions — i.e., forced guided contacts, tamper resistant mechanism — allowing the machine to be safeguarded in compliance with the machine directive.

MT-GD2 Universal with Metal Housing

The MT-GD2 is a robust tongue actuated safety interlock switch designed to fit at the opening edge of sliding, hinged or lift-off guards. With its dual entry slots and rotatable head, the MT-GD2 can offer eight different options for actuator entry.

Features

- Strong and versatile, can be used in most applications
- Self-ejecting tamper resistant actuator, only operates when mounted to the guard
- Four possible actuator entry points, easy to install

Sipha Sensors and Control Units

With the increasing speed and complexity of applications a simple magnetic switch may be insufficient to meet the increased risks, therefore Sipha’s design incorporates several magnetically sensitive elements which must be triggered in a particular sequence to operate correctly. The Sipha sensor, designed to operate with its own actuator, helps prevent defeatability by a simple magnet.

Features

- Noncontact actuation
- Magnetic coded sensing
- Four housing styles
- Must be operated with its own safety control unit

Tongue Interlock

The Prosafe tongue interlock combines the features of trapped keys with the tongue actuated interlocks. When the tongue (actuator) is inserted into the interlock, the gate is closed. This allows the trapped key to be rotated and removed. When the trapped key is removed, the actuator can not be removed from the interlock and therefore the gate is locked. To allow access to the gate, the trapped key must be inserted into the code barrel and rotated.

These trapped key tongue interlocks are manufactured in 316L stainless steel to provide a rugged, industrial grade method of helping prevent access through gates.
