Frequently Asked Questions
Does this switch include the operating key actuator?
Not included. This listing is for the switch body only; separate AZ 17 series straight, angled, or flexible actuators are required to operate the mechanism.
What is the contact configuration and pinout style?
The switch contains two normally closed (2 NC) positive-break contacts across terminals 1-2 and 3-4, wired through a standard 4-pin M12 male connector.
What is the function of the R latching option?
The R designation provides an internal 30 N retaining latch force. This mechanical detent keeps the door or guard held shut to prevent unintended bouncing or vibration from opening the safety circuit.
Can this switch be used in washdown or dusty environments?
Yes. The housing carries an IP67 rating and is constructed from glass-fiber reinforced thermoplastic, making it dust-tight and protected against temporary immersion in water.
Industrial safety gear works best when it is so reliable you forget it is there. Bolt it to the gate, plug in the M12 lead, and keep your machinery running safe.
