AZM 170
The AZM 170 series from Schmersal is the compact electromechanical solenoid interlock in a plastic enclosure. It keeps the guard door closed until the hazardous overtravel has ended, providing a holding force of 1,000 N to EN ISO 14119. With 90 variants it is the most varied series in the range.
What the AZM 170 is designed for
1,000 N of holding force suits light to medium guard doors — panels, flaps and doors that do not have to absorb large masses. Where higher forces are needed, the AZM 161 with 2,000 N or the AZM 415 with up to 3,500 N is the right choice. The coding level to EN ISO 14119 is low; for high coding there is the identically built AZM 170I.
Design and characteristic data
The enclosure of glass-fibre reinforced, self-extinguishing thermoplastic is double-insulated to protection class II and rated IP67. Depth is 30 mm, width and height vary between 108 and 122 mm and between 75.5 and 100.5 mm depending on the version. Mechanical life is 1,000,000 operations, the permissible ambient temperature range −25 to +60 °C.
Contacts, connection and release
Depending on the version, one to four safety contacts and up to two auxiliary contacts are available, all as positive-break NC contacts. Connection is via screw or cage clamp terminals or M12 connectors. The control supply voltage is available in 24 V DC and several AC versions — a difference from the newer RFID series, which work exclusively with 24 V DC. The rotary release is standard.
Standards and Performance Level
The series meets EN IEC 60947-5-1, EN ISO 13849-1 and EN ISO 14119. Single-channel it reaches Performance Level c at category 1, with fault exclusion at the actuator Performance Level d. Some of the variants are additionally cULus certified. The safety-related characteristic data is given in full with every article — you do not need a further data sheet for your risk assessment.
